Main branch-circuit fuses provide overcurrent protection in the event of short-circuits, power surges, damage to electrical wiring, etc…by interrupting faulty circuitry and removing it from the electrical system. In addition, the molded case switch can disconnect power from the source prior to known electrical disturbances, before the fuse is required to operate. Integrated into the molded case switch is an electromagnet (shunt trip coil), controlling a spring-loaded conductivestrip which maintains continuity between the line side and load side terminals of the switch. The electromagnetic coil is normally connected to a safety system, such as a fire alarm or smoke detector housed in the surrounding building. Should there be an electrical emergency, a signal is sent to the coil (via the safety system, alarm, sprinkler, etc…) and the electromagnet would be engaged, throwing the switch and disconnecting power. Power can only then be reenergized by manually operating the molded case switch. • Fusible Shunt Trip Switch 3D A N g e r A N D WA r N I N g L A b e L SU L L I S T I N g I N F O r M AT I O NStep 1: Disconnect power from the circuit where the fusible shunt trip switch will be installed. Mount the panel. Wire up the line side three phase conductors into the three line side terminals of the molded case switch (L1, L2 and L3). Wire the load side to the three load side terminals of the class J fuseholder (T1, T2 and T3).Step 2: Wire the remote control elements to the specified terminal blocks shown in the wiring diagrams on page 6 and 7 (120VAC and 24VAC/DC respectively) of this manual. For 120VAC, safety system controls must supply a set of dry (no voltage) contacts. For 24VAC/DC, safety system controls must provide the voltage source.Step 3: Connect power to the circuit on which the fusible shunt trip disconnect switch is installed. T est the shunt trip operation. Close the molded case switch manually; the pilot light (if installed) indicating that the switch is closed will indicate. engage the key switch (if installed) to activate the shunt trip and trip the molded case switch. The switch will trip and the pilot lightwill turn off.e S S e r I e S–F U S I b L e S h U N T T r I P D I S C O N N e C T S W I T C hFire Alarm Voltage Monitoring relay included in all Mersen offerings. No additional part suffixes required. (Competitor Options F1 and F3)*Neutral lug rating should be greater than or equal to the switch ampere rating. For 200% lug over sizing, select next higher rating. N4 is suitable for 200% over sizing at 400A. • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 5Minimum – This sizing is recommended if motor acceleration time does not exceed 2 seconds. Minimum sizing with class J fuses will provide overload relay back up protection but may not coordinate with some NeMA Class 20 overload relays. Minimum sizing is generally not heavy enough for motors with code letter g or higher.Typical – Suggested for most applications. Will coordinate with NeMA Class 20 overload relays. Suitable for motor acceleration times up to 5 secondsHeavy – Maximum allowable fuse size when an overload relay or motor thermal protector is included in the branch circuit. If this fuse size is not sufficient to start the load, class J time-delay fuses may be increased to a maximum of 225% of full load amperes. Suggested for Design e and high efficiency Design b motors.Notes:1. Tb-5 and Tb-9 must be dry (no voltage) normally open contacts from safety system2 . If a surge protection option is selected, it will be corrected line to ground between the STS and fuses F1-F3 • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 7Notes: 1.For 24VAC control systems, 24VAC must be connected between Tb-5 and Tb-3. For 24VDC control systems, 24VDC must be connected between Tb-5 and Tb-3. Do not source AC voltage into a DC control system or vice versa.2 .If a surge protection option is selected, it will be connected line to ground, between the STS and fuses F1-F3. • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 9M A I N T e N A N C eThe following preventative maintenance measures should be considered in order to maintain product integrity •Periodically clean product exterior and interior to remove any dust, particles, tools or other. Follow proper safety precautions when performing maintenance.•Periodically check lug torque values in order to maintain product specifications. recommended torque values for all parts are shown on page 8 of this manual.

漏电保护器使用说明书

漏电保护器使用说明书漏电保护器，简称漏电开关，又叫漏电断路器，主要是用来在设备发生漏电故障时以及对有致命危险的人身触电保护，具有过载和短路保护功能，可用来保护线路或电动机的过载和短路，亦可在正常情况下作为线路的不频繁转换启动之用。

国家为了规范漏电保护器的正确使用，相继颁布了《漏电保护器安全监察规定》（劳安字（1999）16号）和《漏电保护器安装与运行（GB13955-92）等一系列标准和规定。

依据这些标准和规定，我们在选用漏电保护器时应遵循以下主要原则：1. 购买漏电保护器时应购买具有生产资质的厂家产品，且产品质量检测合格。

在这里要提醒大家：市场上销售的漏电保护器有不少是不合格品。

2002年10月28日，国家质检总局公布漏电保护器产品质量抽查结果，有20%左右的产品不合格，其主要问题为：有的不能正常分断短路电流，消除火灾隐患；有的起不到人身触电的保护作用；还有一些不该跳闸时跳闸，影响正常用电。

2. 应根据保护范围、人身设备安全和环境要求确定漏电保护器的电源电压、工作电流、漏电电流及动作时间等参数。

3. 电源采用漏电保护器做分级保护时，应满足上、下级开关动作的选择性。

一般上一级漏电保护器的额定漏电电流不小于下一级漏电保护器的额定漏电电流，这样既可以灵敏地保护人身和设备安全，又能避免越级跳闸，缩小事故检查范围。

4. 手持式电动工具（除III类外）、移动式生活用家电设备（除III 类外）、其他移动式机电设备，以及触电危险性较大的用电设备，必须安装漏电保护器。

5. 建筑施工场所、临时线路的用电设备，应安装漏电保护器。

这是《施工现场临时用电安全技术规范》（JGJ46-88）中明确要求的。

6. 机关、学校、企业、住宅建筑物内的插座回路，宾馆、饭店及招待所的客房内插座回路，也必须安装漏电保护器。

7. 安装在水中的供电线路和设备以及潮湿、高温、金属占有系数较大及其他导电良好的场所，如机械加工、冶金、纺织、电子、食品加工等行业的作业场所，以及锅炉房、水泵房、食堂、浴室、医院等场所，必须使用漏电保护器进行保护。

EOCR过电流操作说明及设置

0EOCR——SS电子式过电流继电器
1、在电动机启动前，根据电机实际启动时间，将启动延时（D——TIME）旋钮调到该值（最
好多加2~3秒），如无法确定，可将该旋钮调到最大值。

2、将动作延时旋钮（O—TIME）及过电流设定钮（LOAD）调整到最大值。

3、启动电机，待电机运行平稳后（即超过起动延时时间D—TIME值）,将过电流设定旋钮
（LOAD）逆时针方向缓慢旋转到红色指示灯（LED）亮为止，此点为实际运行电流值的100%。

再将旋钮顺时针方向旋至红色指示灯刚刚熄灭处（在动作延时O—TIME设定时间内）,此点为实际运行电流值的103%。

继续顺时针方向旋转过电流设定钮（LOAD），将其设定在合适的过电流值上。

（推荐过电流值为实际运行电流值的110%~125%之间）4、根据电机正常起动运行情况，重新校准起动延时时间（D—TIME）。

一般设定值比实际
值大2~3秒。

5、依据实际情况重新设定动作延时（O—TIME）时间。

6、设置后应按测试钮（TEST）来检查设置结果。

口面板结构图
测试按钮使用说明
工作中应对继电器进行测试，方法如下：
在无负荷状态下，按动测试按钮（TEST）不松手，此时红色指示灯亮。

经过起动延时时间后，可听到“哒”的一声继电器动作声，此时，松开测试按钮（TEST），红色指示灯常亮，表示继电器工作正常。

完成上述工作后按复位（RESET）钮复位，进入正常工作状态。

2.起动延时时间设置过电流值设置完成后，再按UP 键，即可看到显示。

dt 表示起动延时；10表示延时时间为10秒。

电机起动时其起动电流要达到电机额定运转电流的5-7倍。

电机的起动电流在其转数没有达到额定转数的80%之前并不减少；当达到额定转数的80%以后起动电流急剧下降至额定电流值（过电流设定值）以下。

电流变化曲线与过电流设定值交叉点的时间就是电机起动延时时间D-TIME （参见右图）。

电机及负载类型不同，起动时间也不一样。

设定时应根据具体情况在实际起动时间基础上多加2-3秒钟，设定范围为为1-200秒，设定时可在状态下按“SET/store ” 键后按左右键选择合适的时间值，再按“ SET/store ”键将设定值存贮即可。

3.动作延时时间设置完成上述设置后，按UP 键，就是动作延时时间设置。

eocrss电机保护说明书

EOCR-SS电子式过电流继电器尺寸：特点：两个电流互感器抗冲击电流电机起动延时（D-time）,脱扣延时（O-time）可独立连续设定。

概述：两个电流互感器监视三相电机中二相电流，当负载电流超过60A 后，需要外加CT。

内置的比较电路比较负载电流与预先设置的过载保护电流，当负载电流持续增大时，红色的LED灯闪亮，经过预先设定的延时时间后，继电器动作，内部触点由闭合状态转变为断开，控制外接接触器脱扣。

此时，红色的LED指示灯保持长亮，绿色指示LED灯保持熄灭，表示一个脱扣动作发生。

要使它恢复常态可人工按前面板的<RESET>按键一次，或切断继电器控制电源供电一次,对它实施复位。

当电机实际电流达到预先设定的保护电流点时，红色的LED指示灯亮度为100%，所以，它可以代替电流表指示电机负载电流。

OT：当电机负载电流超过预先设定的保护电流值后，电流持续增加，经过OT设置时间后，电流并没降低，继电器立即动作。

控制外接接触器脱扣，保护电机。

设置范围：0.2-10秒。

两个独立的延时调整旋钮可各自设定电机启动延时（DT）和过载脱扣延时（OT），已确保继电器不发生误动作。

《TEST》按键用于测试继电器脱扣动作。

DT：电机启动过程中，电流是正常负载电流的5-7倍，此延时设置，保证电机启动过载期间不动作。

设置范围：0.2-30秒。

前面板图示：特性：电流设定型号范围050.5-6A(6.5)303-30A(35)605-60A(70)70A以上电流,需配合外加电流互感器使用延时设定起动延时(D-time)0.2-30秒,连续可调脱扣延时(O-time)0.2-10秒,连续可调工作电压22090-250V(50/60Hz) 440320-480V(50/60Hz)触点形式1-SPDT(1C)容量3A/250V(AC)静态98-95常开“N”96-95常闭“R”延时特性定时限脱扣指示LED(亮)安装方式35毫米固定/道轨式使用调整方法:1、把继电器正确接入电机控制回路,根据具体情况分别整定继电器面板的起动延时、脱扣延时旋钮,设置正确的延时时间。

参照EOCR-3DM 典型接线图完成接线。

根据实际情况将功能开关选择在合适的位置上（参照上述说明）。

接通工作电源，按下述方法设置参数。

□ 过电流值设置按UP 位置。

这里0.5表示过电流值0.5A 。

若要改变此值，需按“SET/store ”键，然后按左右键调整，上述的值即可改变。

把这个值调整到电机铭牌上规定的额定值上（如无此值，推荐将此值放在电机实际运行电流的110-125%之间）。

再次按动“SET/store ”键，将该值存贮起来即可。

2.起动延时时间设置过电流值设置完成后，再按UP 键，即可看到显示。

dt 表示起动延时；10表示延时时间为10秒。

电机起动时其起动电流要达到电机额定运转电流的5-7倍。

电机的起动电流在其转数没有达到额定转数的80%之前并不减少；当达到额定转数的80%以后起动电流急剧下降至额定电流值（过电流设定值）以下。

电流变化曲线与过电流设定值交叉点的时间就是电机起动延时时间D-TIME （参见右图）。

电机及负载类型不同，起动时间也不一样。

设定时应根据具体情况在实际起动时间基础上多加2-3秒钟，设定范围为为1-200秒，设定时可在状态下按“SET/store ” 键后按左右键选择合适的时间值，再按“ SET/store ”键将设定值存贮即可。

产品使用说明书(GRZL智能漏电断路器)

O 附录：智能漏电断路器——自动跟踪定档与合闸记忆功能的说明为满足用户的要求，本公司在智能漏电断路器（以下简称漏电断路器）的基础上增设剩余电流自动跟踪定档功能与记忆功能。

该功能是依据基层电力管理部门的建议，为解决线路剩余电流随用电负荷大小变化，以及随季节和天气晴雨变化使用电管理者难以对保护装置的手动动作档位进行合理的设定，无法根据线路实时剩余电流状态使故障接地危险电流在较小的额定动作值下正确保护运行这个难题而开发研制的。

该功能的实现，能科学的、合理的根据线路剩余电流的变化自动确定适当的动作值档位，当线路发生危险的接地故障漏电时，使保护装置在较小的动作值档位下动作，解决了使用管理上的难题，有利于较大地提高剩余电流保护装置的投运率和可靠性，扩大保护面，提高对供电线路剩余电流的安全保护性能。

1、线路剩余电流的变化与自动跟踪定档当漏电断路器剩余动作电流在1000mA，处于自动跟踪定档工作模式时，开机后，会自动把档位设定在1000mA上。

这时如果线路实际剩余电流小于400mA时，1-2分钟漏电断路器就会自动跟踪到800mA，如果线路实际剩余电流小于300mA时，漏电断路器会自动跟踪到600mA时，如果线路实际剩余电流小于200mA。

漏电断路器再会自动跟踪400mA时，如果线路实际剩余电流小于100mA时，漏电断路器再会自动跟踪到200mA时。

在自动跟踪定档下，线路剩余电流突然增加到自动跟踪的设定值时，漏电断路器马上跳闸（如漏电断路器处于600mA自动跟踪定档时，线路剩余电流突然增加到600mA，漏电断路器马上跳闸），20-60s内漏电断路器自动重合闸，重合闸后，漏电断将自动跟踪定档自动升上一档，如果线路剩余电流仍大于比上升后的定档值大，漏电断路器再次跳闸并闭锁（跳死），依此类推。

如果线路剩余电流缓慢增加，漏电断路器同时也能随着线路剩余电流增加而自动上升，一直变换到接近自动跟踪定档的最高档为止。

如果漏电断路器的自动跟踪档档位处于1000mA，线路的剩余电流缓慢下降，那么漏电断路器动作值就会自动下降，随着实际剩余电流的不断缓慢下降，档位会一直降到最低档，即200mA为止。
