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 ...

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 ...

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

Understanding the overcurrent trilogy will help you protect your circuits. Circuit overcurrent protection encompasses overload, short-circuit, and ground-fault protection. NEC Art. 100 defines ...

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 ...

All of this can be accomplished with the use of a SCADA system within the automation process. However, none of these functions are available if the system is not designed with a reliable power source ...

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 ...
