8~65kA 4 Pole MCCB Circuit Breaker Reliable Performance High Breaking Capacity

Specifications

Main Functions

• Protection against overload – currents above the rated value that last longer than what is normal for the application.
• Protection against electrical faults – During a fault such as a short circuit or line fault, there are extremely high currents that must be interrupted immediately.
• Switching a circuit on and off – This is a less common function of circuit breakers, but they can be used for that purpose if there isn’t an adequate manual switch.
