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 ...

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 ...

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 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.

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

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 ...

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 ...
