Overview

The ABB Electrification THQB32100ST1 is a 1-pole, 100 Amp bolt-on circuit breaker from the Q Line QB series, engineered for reliable overcurrent protection in residential and commercial electrical systems. This compact, thermal-magnetic device features a 1-inch width per pole, optimizing panel space while ensuring straightforward installation. As a bolt-on version of the Q Line, it provides a secure, direct connection to the bus bars of load centers and lighting panels, eliminating the need for additional mounting hardware and reducing installation time. Its Quick-make / Quick-break mechanism ensures rapid contact operation, minimizing arcing and wear during switching. The breaker includes a common trip bar for coordinated protection and an easy-to-spot trip indication for simplified troubleshooting and maintenance. The 'ST1' terminal configuration accommodates specific bus bar arrangements, requiring 4 pole spaces (3P+1ST) in the panelboard for accessory configurations or advanced setups. Manufactured by ABB, a leader in electrical solutions, the THQB32100ST1 combines durability with precision engineering, ensuring dependable performance in demanding environments. Its non-interchangeable trip style prevents unauthorized adjustments, enhancing system integrity. Ideal for panelboards, lighting panels, and distribution boards, this breaker is a cost-effective solution for protecting circuits against overloads and short circuits.
