High-Speed DC Circuit-Breakersfor Industry
Type UR6 and UR15
The UR6and UR15are DC high-speed current-limitingcircuit-breakers with natural cooling, trip free, singlepole, bi-directional, with electromagnetic blow-out,electric control circuits and direct over-current instanta-neous release.The UR6 and UR15 circuit-breakersare of open typeconstruction.
Their simple design and high insulation level combinedwith their compliance to IEC60947 standard for industry,EN50123/ IEC61992 standards for fixed installationsand EN/IEC60077 standard for rolling stock (more
severe for what concerns the mechanical enduranceand the vibrations & shocks, guarantee tothe UR6 andUR15 a very high reliability and an exceptionally long lifetime.
With its proven worldwide experience and acceptance,Sécheron's range of circuit-breakers offers you the keyproduct for such a strategic and critical application thatis to guarantee the highest safety to your equipment aswell as to the people operating it and using it.

Be sure to establish the designation code from our latest version of the brochure by downloading it from our website“”.
Be careful to write down 20 digits for the type designation code when placing your order.
The bold part of this designation code defines the device type and the complete designation defines the identificationnumber of the product, as they are displayed on the identification plate attached to the product.The customer shall write down the setting value Ids in its order form.
It can happen that for technical reasons, some configurations of variants and options indicated in the designationcode cannot be combined.
