Circuit breakers are used in a variety of ways. They are mounted in panelboards to protect branch circuit wiring, and they are built into equipment to protect it. With this range of applications, it's ...

Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

This voltage regulator delivers smooth control of a constant voltage from 0 to 8 V. It protects the load against short circuits and indicates connection, overload, and output level. The series chain ...

To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...

It features a standard 2.5-sq-mm screw-clamping system (22 to 12 awg), and accepts a standard 5 20-mm fuse. Various LED options provide blown fuse indication across a voltage range of 10 to 250 V. The ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...

Self-protecting starters (SPSs) were first introduced to the U.S. in 1987. However, SPSs have been used internationally for several years. Recently, several manufacturers and private labelers have ...
