The Schneider Electric Merlin Gerin MG685679 is an Under Voltage Release designed to enhance the safety and operational integrity of electrical distribution systems. This accessory is engineered to integrate with specific Schneider Electric Merlin Gerin circuit breakers, providing essential protection against voltage sags and failures. Its function is to trip the associated circuit breaker when the supply voltage drops below a predetermined threshold, preventing damage to connected equipment and ensuring personnel safety.

Technical details

• Product Type: Under Voltage Release (UVR)
• Manufacturer Series: Merlin Gerin
• Model Number: MG685679
• Function: Trips associated circuit breaker upon detecting under voltage conditions.
• Operating Principle: Electromechanical release activated by a drop in supply voltage.
• Compatibility: Designed for specific Schneider Electric Merlin Gerin circuit breaker frames. Refer to manufacturer documentation for precise breaker model compatibility.
• Voltage Sensitivity: Operates when voltage falls below a calibrated level, typically a percentage of nominal voltage. Specific trip voltage and reset voltage values should be confirmed via datasheet.
• Reset Mechanism: Requires manual reset of the associated circuit breaker after the voltage condition has been rectified.

Applications & compatibility

This under voltage release is crucial for applications requiring protection against power quality disturbances, such as in manufacturing facilities, data centers, and critical infrastructure. It is commonly employed in conjunction with Merlin Gerin circuit breakers installed in distribution panels for machinery, control systems, and essential services where continuous and stable power is paramount.
