What is an arc chute?

When a circuit breaker interrupts high currents, an electric arc is generated. An electric arc is the discharge of electric current through gas or air. The conduction of electric charges…

Difference between Short circuit and overload

Short Circuit A short circuit occurs when two or more current-carrying conductors of different phases or different voltage levels or different terminal (in DC circuits) come in contact with each…

Difference between circuit breaker and isolator

Isolator/ Disconnectors

Isolator or disconnectors, as the name indicates, is a switching or isolation device, intended to disconnect an equipment or electrical Circuit from the supply. It is an offload device, which means it can be operated only when the current passing through it is zero. Unlike circuit breakers, it lacks a built-in arc suppression system. It can be operated only during offload conditions. (more…)
