Overload devices protect motors, motor control equipment, and motor branch-circuit conductors against excessive heating due to motor overloads and failure to start, but not against overcurrent (e.g., ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

This application note presents the Analog-to-Digital converter input buffer and protection techniques designed for maximized and reliable data acquisition. The document also briefly describes the SCR ...

The 2026 National Electrical Code clarifies rules for 10 amp branch circuits, conductor sizes and permitted uses for LED ...

A key subsystem in a programmable logic controller is the analog input module, which provides a high-precision front end to measure a wide variety of sensors. In many cases, however, the amplifier ...

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 ...

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 ...
