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 ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

Medium- and high-voltage systems that range from 9 to 72 V often require one or more of the following circuit capabilities: hot-swap control, circuit-breaker fault protection, and inrush current ...

Reviewing a typical protective device trip curve (click here to see Fig. 2), it can be divided into three regions. First is the “instantaneous region,” which is the region intended to interrupt ...

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 ...

Description: NOARK introduced the latest edition to its B1N miniature circuit breaker family: the UL 489 B1NQT. This recyclable, quick-connect circuit breaker is available in three curves (B, C, and D ...
