Two new models have been added to the connectPower line of DIN-rail mounted circuit breakers from Weidmuller, Richmond, Va. BR Series circuit breakers are UL 489 Branch rated and SU Series circuit breakers are UL 1077 approved for Supplementary protection.
Lever-operated breakers use thermal-magnetic technology, having ratings up to 277/480 V and 60 A in 1, 2 and 3 pole formats, and are available immediately with C or D trip characteristics. The ranges are designed for industrial control applications, especially where the control equipment may be in an environment that needs to resist vibration and mechanical shock.
A compact 17.5-mm width on the rail is standard. Both series give users the option of using either wire-end ferrules or ring lug terminations for the supply and load, as well as UL-approved bus-bar accessories to simplify and reduce the installation time. To maximize security and safety, the operating lever can be locked, off or on, and even the IP20 connections can be supplied with optional touch protection caps.
