Electronic molded case circuit breaker DS-3E 1250A 3P 240V with mounted MN

Molded Case Circuit Breaker with an under-voltage release is a type of MCCB that includes an additional protective device designed to automatically trip the circuit breaker when the supply voltage falls below a certain predetermined value. The under-voltage release is an auxiliary device that adds an extra layer of protection to the electrical circuit. The under-voltage release is designed to monitor the supply voltage level. When the voltage drops below a specific threshold, typically set below the normal operating voltage, the under-voltage release is activated. Once the under-voltage release is activated due to the low voltage condition, it triggers the tripping mechanism of the MCCB, causing it to open and interrupt the circuit, thereby cutting off the power supply. The under-voltage release adds an additional layer of protection to the MCCB, allowing it to respond to low voltage conditions and prevent potential issues or damage to connected equipment. As with any electrical device, its essential to ensure proper selection, installation, and compliance with safety standards to ensure reliable and safe operation.
