## Summary description

The Schneider Electric MN undervoltage release (LV429408) is an essential accessory for Compact NSX circuit breakers. Designed for 380-415VAC operation, this device ensures safety by tripping the circuit breaker when the control voltage drops below a specified threshold. It is ideal for industrial power distribution systems requiring reliable protection against voltage instability and emergency shutdown capabilities.

## Long description

The Schneider Electric MN undervoltage release is a specialized safety accessory engineered for integration with Compact NSX circuit breakers. This device is designed to monitor control voltage levels and automatically trip the circuit breaker if the voltage falls below a predefined threshold, typically between 35% and 70% of the nominal voltage. By ensuring that the circuit is disconnected during power instability, it prevents potential damage to connected equipment and enhances overall system safety in industrial environments.
Advantages
This undervoltage release provides a robust solution for emergency shutdown applications and system protection. Its primary benefit lies in its ability to provide a fail-safe mechanism that reacts instantly to voltage drops, thereby protecting sensitive electrical infrastructure from the risks associated with low-voltage operation. The component is built to the high standards of Schneider Electric, ensuring reliable performance, seamless compatibility with the Compact NSX range, and long-term operational stability in demanding power distribution networks.
Suitable for
Industrial power distribution systems
Emergency stop circuits
Protection against voltage instability
Automated shutdown sequences
This device is not suitable for applications where the control voltage is outside the specified 380-415VAC range. It is also not intended for use with circuit breakers outside the Compact NSX series, as it requires specific mechanical and electrical interfaces to function correctly.
Key specifications
Control voltage: 380-415VAC
Compatibility: Compact NSX circuit breakers
Function: Undervoltage tripping
Operating threshold: 0.35 to 0.7 Un
Installation of the MN undervoltage release should be performed by qualified personnel in accordance with the manufacturer's technical documentation. The device is typically mounted within the internal accessory compartment of the circuit breaker. Ensure that the power supply is completely disconnected before attempting to install or service the unit to prevent electrical hazards.
What to consider before purchase
Verify the control voltage of your existing electrical system
Confirm compatibility with your specific Compact NSX circuit breaker model
Ensure installation is performed by a certified electrician
For optimal reliability, regularly test the tripping function during scheduled maintenance intervals to ensure the undervoltage release remains responsive to voltage fluctuations.
