The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

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 ...

If an application requires writing to EPROM devices after deployment, 5V devices need to be protected from overvoltage exposure. This article explains how to have 1-Wire EPROMs and 5V 1-Wire devices ...

An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...

From traditional fuses to eFuses, understanding the advantages, limitations, and use cases of each technology helps engineers ...

An ideal protection device must limit the energy going to the load being defended, to a sufficient minimum level, such that the load is not damaged. The protection device must survive this energy ...
