Square D NA11143 is a Type NA Under Voltage Release designed for circuit breaker protection by automatically tripping the breaker when voltage drops below a preset threshold. It operates with a control voltage range of 24 Volts minimum to 24 Volts maximum, ensuring precise low-voltage response. This unit weighs 2 lb and is constructed for integration into Square D Series circuit breaker families. It complies with industry standards for reliable undervoltage protection in industrial electrical systems. Typical applications include motor control centers and distribution panels requiring voltage-sensitive safety disconnects.
