The Eaton NZM4-XU208-240AC is an undervoltage release (UVR) accessory specifically designed for the NZM4 series of molded case circuit breakers.This undervoltage release provides important protection by automatically tripping the circuit breaker when the supply voltage drops below a predetermined threshold (typically 35%-70% of rated voltage) or is completely lost. It also prevents the breaker from being closed when voltage is absent or insufficient, ensuring operational safety and protecting equipment from undervoltage operation.
