Overview
The General Undervoltage Release is a key accessory for DLM1, DLM1E, and DLM1LE Series Molded Case Circuit Breakers (MCCBs).
It provides automatic tripping protection when the control voltage drops below a preset threshold, ensuring that electrical equipment and circuits are safely disconnected during abnormal voltage conditions.
When the supply voltage falls to a dangerous level (typically below 70%–35% of rated voltage), the undervoltage release automatically opens the MCCB, preventing malfunction or damage to sensitive electrical equipment. Once the voltage returns to normal, the breaker can be manually or automatically reclosed depending on system configuration.
Available in Two Connection Types:
-
With Lead Wires: flexible and easy to connect, suitable for compact control panels.
-
With Terminal Connection: firm and reliable for fixed installations in industrial environments.
Key Features:
