CELPK1111-40014-200 Application Field and Working Principle

Circuit breakers are switching devices used to break off circuits or protect circuits from overload. CELPK1111-40014-200 is an insulated-case type circuit breaker developed by China Electric Lompen. It is mainly used for protection accross liners, busbars, transformers, motors, generator sets and other equipment.

The CELPK1111-40014-200 can protect cables and other components from the negative effects of arc-fault, overload, and short circuits. The product applies the advanced vacuum interrupter which has the advantages of high breaking capacity, long life and reliable performance.

The work principle of CELPK1111-40014-200 is simple but effective. The circuit breaker contains two contacts which are separated by an insulation gap. When the contact is in the ‘close’ state, current flows from one contact to the other and the protected circuit is in operation. When the contact is in the ‘open’ state, no current flows. The circuit breaker is opened by an actuating member such as a mechanical lever arm, plunger or solenoid. The actuating member in turn activates the external contacts which are separated by an insulation gap and an actuating device, thus breaking the circuit.

The CELPK1111-40014-200 has multiple protection functions, such as over-current protection, reverse-phase protection, earth-leakage protection, over-voltage protection and isolation protection. It is highly reliable, with a rated short-circuit non-trip duration of up to 2000ms.

In summary, CELPK1111-40014-200 is an insulated-case type circuit breaker developed by China Electric Lompen. It applies the advanced vacuum interrupter and can provide multi-level protection for cables and other components. It is widely used in electrical systems and industrial facilities.
