Why Choose the CHINT NS2-25-AU11 Undervoltage Release?

The CHINT NS2-25-AU11 is a reliable undervoltage release accessory designed specifically for CHINT NS2 manual motor starters and motor protection circuit breakers. This module automatically trips the motor starter when the control voltage falls below a specified threshold, helping protect motors and machinery against unsafe restart conditions and abnormal voltage drops in industrial power systems.

Engineered for industrial automation and motor control applications, the NS2-25-AU11 improves operational safety by ensuring that motors cannot automatically restart after a power failure until the control circuit is intentionally reset. This functionality is essential for protecting personnel, machinery and production systems in industrial environments.

The compact side-mounted accessory design allows quick integration with compatible CHINT NS2 motor starters, making it suitable for OEM machinery, HVAC systems, pump controls, conveyor systems and industrial automation panels. Manufactured to IEC/EN standards, the unit delivers dependable long-term performance in demanding operating conditions.
