The Schneider Electric GVAU505 is an undervoltage release (MN) designed for use with the TeSys GV2 and GV3 series motor circuit breakers. This accessory provides essential protection by tripping the circuit breaker when the supply voltage drops below a predetermined level, preventing damage to connected equipment and ensuring operational safety in industrial environments.

Technical details

• Series: TeSys GV2-GV3
• Accessory Type: Undervoltage Release (MN)
• Rated Voltage (AC): 500V AC at 50Hz
• Rated Voltage (AC): 600V AC at 60Hz
• Functionality: Provides undervoltage protection, tripping the associated circuit breaker upon voltage loss.
• Compatibility: Designed for integration with Schneider Electric TeSys GV2 and GV3 motor circuit breakers.
• Mounting: Typically mounts directly onto compatible TeSys GV2 or GV3 devices.
• Trip Mechanism: Electromechanical release triggered by voltage drop.

Applications & compatibility

This undervoltage release is critical for applications requiring reliable motor protection, such as in pump control systems, fan drives, and conveyor systems where sustained operation under fluctuating voltage conditions is undesirable. It ensures that machinery does not restart unexpectedly after a power interruption or voltage sag, safeguarding personnel and preventing damage to equipment in manufacturing plants, water treatment facilities, and HVAC systems.
