MCCBs equipped with both shunt release and auxiliary contacts offer a wide range of applications, particularly in scenarios where remote operation, control, and monitoring capabilities are required. The shunt release is an auxiliary device that provides remote tripping capability for the MCCB. It is an electromechanical component that is typically energized by an external control signal, allowing for remote operation of the circuit breaker. When the shunt release coil is energized, it creates a magnetic field that acts on the trip mechanism, causing the MCCB to trip, even if there is no overload or fault condition detected by the MCCBs primary trip unit. The shunt release allows for rapid disconnection of the circuit breaker from a distance, making it suitable for applications where manual intervention may not be practical or safe. The auxiliary contacts are additional electrical contacts mechanically linked to the MCCBs operating mechanism. They change their position according to the status of the circuit breaker, indicating whether it is open or closed. The auxiliary contacts can be used for various control and signaling purposes, such as interlocking, control signals for other devices, remote monitoring, or signaling alarms. The combination of shunt release and auxiliary contacts in an MCCB provides enhanced functionality, making it suitable for various industrial, commercial, and utility applications. As with any electrical device, proper selection, installation, and compliance with safety standards are essential to ensure reliable and safe operation.
