Overview

The ABB Electrification Q Line miniature circuit breaker, SKU THQC32020WL, is a compact, 20 Amp thermal-magnetic device designed for reliable protection in residential and commercial electrical systems. This lug-lug version of the Q Line series is engineered for efficient 35mm DIN rail mounting, enabling streamlined installation in panel boards and distribution boards. Key features include a quick-make/quick-break mechanism for rapid contact engagement and disengagement, minimizing arcing and extending operational lifespan. The common trip bar ensures simultaneous operation across all poles, preventing single-pole tripping in multi-pole configurations. An easy-to-spot trip indication provides immediate visual confirmation of a tripped breaker, enabling quick fault identification and resolution. This 1-pole configuration is rated for 20A continuous current and supports system voltages of 120 Vac, 120/240 Vac, and 240 Vac. The breaker offers a 22,000 AIC (Amperes Interrupting Capacity) rating, ensuring robust fault protection. It is also suitable for reverse feed applications and carries HACR (Heating, Air Conditioning, and Refrigeration) marking, making it compatible with HVAC systems. The Q Line series is available in 1, 2, and 3 pole versions and can be enhanced with optional auxiliary contact and shunt trip accessories to meet specific application requirements. Manufactured by ABB, this circuit breaker is built for durability and reliability in demanding electrical distribution environments.
