Chint 3kA 2P 40A circuit breaker c-curve

The Chint 3kA 2P 40A Circuit Breaker C-Curve is an electrical protection device that is designed to interrupt electrical current flow in the event of a fault. This specific circuit breaker has a breaking capacity of 3 kilo-amperes (3kA) and is a two-pole (2P) breaker, meaning that it can interrupt current flow in two separate conductors simultaneously.

The “3kA” rating indicates the maximum amount of fault current the circuit breaker can safely interrupt without sustaining damage. The “2P” designation means that the circuit breaker is a two-pole device, capable of interrupting both the live and neutral conductors in a circuit. The “40A” rating indicates the maximum continuous current that the circuit breaker can handle without tripping.

The “C-Curve” refers to the trip characteristic of the circuit breaker. C-Curve breakers are designed to trip quickly in response to short circuits and overloads, but are also able to handle small amounts of inrush current associated with some loads, such as motors and transformers. They are commonly used in residential and commercial applications where moderate to high inrush currents are expected.

Overall, the Chint 3kA 2P 40A Circuit Breaker C-Curve is a reliable and safe option for protecting electrical circuits against overcurrents and short circuits in various applications.
