Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...

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 ...

Circuit breakers are manual switches that open under overload conditions. Circuit breakers are manual switches that open under overload conditions. Circuit breakers discussed here are general-purpose ...

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 ...

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 ...

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 ...

Last month, we discussed the protective devices coordination procedure for a low-voltage motor and demonstrated how the ratings and settings of branch circuit and short circuit protective devices are ...

A new supplement to the UL codes dictates all low-voltage control panels be rated for short-circuit current. Those who work in the electrical industry always support one common goal — the safe ...
