DS1 MAX 250/200+MN+OF 230V 3P

MCCBs equipped with both under-voltage release and auxiliary contacts offer a wide range of applications, particularly in scenarios where additional control, monitoring, and protection features are required. The under-voltage release is an auxiliary device that monitors the supply voltage level. If the voltage falls below a predetermined threshold, the under-voltage release activates and triggers the tripping mechanism of the MCCB, causing it to open and interrupt the circuit. This protection feature helps prevent equipment damage or malfunctions due to low voltage conditions. 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. These auxiliary contacts can be used for control signals, remote monitoring, interlocking, or signaling alarms, depending on the specific application. The combination of under-voltage release and auxiliary contacts in an MCCB offers comprehensive protection and control, making it suitable for a wide range of applications in industrial, commercial, and utility settings. As with any electrical device, proper selection, installation, and compliance with safety standards are essential to ensure reliable and safe operation.
