Bulletin 140G molded-case circuit breakers react up to three times faster to minimize downtime Industrial automation customers can improve their short-circuit protection with a new line of ...

A. An overcurrent device (typically a fast-acting fuse) that reduces the fault current to a magnitude substantially less than that obtainable in the same circuit if the current-limiting device wasn’t ...

The ABB Low Voltage Products division has introduced the new S200PR Ring Tongue family of high performance, current limiting miniature circuit breakers (MCBs) with ring tongue lug connections. The ...

The breakers conform to UL 489, CSA 22.2 No. 5 and IEC/EN 60947-2 standards. They are, the company says, currently the only UL489 MCB on the market with rated current up to and including 35 A for 480Y ...

Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

Suitable for use in hazardous and non-hazardous environments, the EC-E circuit breakers selectively protect load circuits connected to a 24-Vdc power supply. The components combine active current ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...
