The Schneider Electric GVAU505 is an undervoltage release accessory designed for the TeSys GV2 and GV3 series of motor circuit breakers. This device provides essential protection by automatically tripping the circuit breaker when the control voltage falls below a critical threshold, preventing potential damage to connected equipment and ensuring operational safety in electrical distribution systems.

Technical details

• Series: TeSys GV2/GV3
• Accessory Type: Undervoltage Release
• Trip Voltage Threshold: Trips when control voltage (Uc) drops below 0.35 Uc.
• Functionality: Provides automatic circuit breaker tripping due to voltage loss or significant undervoltage conditions.
• Compatibility: Specifically designed for integration with Schneider Electric TeSys GV2 and GV3 motor circuit breakers.
• Voltage Rating: Uc (Control Voltage) rating is dependent on the specific breaker and control circuit configuration; refer to manufacturer datasheet for precise Uc values.
• Mounting: Designed for direct attachment to compatible TeSys GV2 and GV3 motor circuit breakers.

Applications & compatibility

This undervoltage release is critical for applications requiring robust protection against voltage fluctuations, commonly found in motor control centers, industrial machinery, and automated production lines. Its compatibility with TeSys GV2 and GV3 breakers makes it suitable for protecting motors in packaging machinery, conveyor systems, pumps, and HVAC equipment where reliable power is paramount.
