Voltage monitoring relay 24V AC/DC GV4 GV4AU027

Undervoltage release for circuit breakers – reliable installation protection

The MN GV4 undervoltage release is a component used to protect circuit breakers from a drop in control voltage. Its function is to disconnect the circuit when the control voltage drops below a safe level, preventing damage and ensuring user safety. The device is compatible with TeSys GV2 and GV3 circuit breakers from Schneider Electric, guaranteeing easy installation and integration with existing systems.

Functionality and application

This release is designed to be mounted on the right side of the circuit breaker (RH) and connected using spring clamps. It reacts to a voltage drop in the range of 0.7-0.35 Uc, making it an effective solution in installations exposed to voltage fluctuations. Because it is an undervoltage release, not a time-delay release, it reacts immediately to a voltage drop, providing a quick response and minimizing the risk of damage. It finds application in a wide range of electrical installations, both in commercial and industrial buildings.

Advantages and benefits

• Protection against voltage drop: Protects circuits from the effects of sudden drops in control voltage, protecting connected devices.
• Compatibility: Designed to work with TeSys GV2 and GV3 circuit breakers, making it easy to integrate with existing Schneider Electric systems.
• Easy installation: Mounting on the right side of the circuit breaker (RH) and connection using spring clamps simplify the installation process.
• Universal power supply: Supports both AC and DC power in the range of 24V, increasing application flexibility.
• Safety certificates: Has certificates of compliance with many standards (IEC, UL, CSA, CCC, EAC), confirming its safety and reliability.
• Compliance with environmental standards: The product meets the Green Premium requirements (RoHs/Reach), demonstrating a responsible approach to the natural environment.

Technical characteristics

The MN 24V AC/DC GV4 release is characterized by the lack of normally open, normally closed, and changeover contacts – its function is solely to monitor the control voltage and initiate disconnection in the event of its drop. The type of electrical connection based on spring clamps ensures quick and reliable contact without the need for tools. The rated control voltage Us is 24V for both AC 50Hz and 60Hz and DC. The device is not intended for use with cam switches or overload relays – its main task is to protect circuit breakers from undervoltage.
