Overview

The ABB THQL32020ST1 is a 3-pole, 20 Ampere, 240V Q-Line shunt trip circuit breaker designed for reliable overcurrent protection and remote tripping capabilities. This breaker features a factory-installed 120 Vac shunt trip module, enabling remote de-energization of the circuit. It is intended for use in combination with a momentary or maintained pushbutton for remote switching operations, providing essential safety and control. With a 20 Ampere rating and a 240V voltage rating, this 3-pole breaker is suitable for 240 Vac applications. The shunt trip functionality is crucial for applications requiring emergency stop capabilities or integration with supervisory control systems, enhancing operational safety by enabling circuit de-energization from an external location. This breaker requires 4 pole spaces for installation and is part of the Q-Line series, known for its plug-in design and compatibility with standard panel configurations. The THQL32020ST1 is ideal for industrial, commercial, and residential applications where remote circuit interruption is required, such as in HVAC systems, motor control centers, and emergency shutdown systems. Its UL and cUL listing ensures compliance with North American safety standards, making it a trusted choice for critical power distribution systems.
