Overview

The ABB THQB32015 is a 3-pole, 15 Amp Q Line bolt-on miniature circuit breaker designed for direct attachment to bus connections in load centers and lighting panels. Rated for 240 Vac operation with a 10,000 AIC interrupting rating, this thermal-magnetic breaker provides reliable overload and short-circuit protection in residential and commercial electrical systems. Its compact one-inch-per-pole design optimizes panelboard space efficiency without compromising performance. This breaker features a Quick-make/Quick-break mechanism for faster contact operation, reducing arcing and extending operational lifespan. A common trip bar ensures simultaneous tripping across all three poles during faults, preventing single-phased conditions that could damage connected equipment. The easy-to-spot trip indicator provides immediate visual confirmation of a tripped breaker, simplifying troubleshooting and maintenance. Part of ABB's Q Line series, the THQB32015 supports system voltages of 120 Vac, 120/240 Vac, and 240 Vac. It is suitable for reverse feed applications and is rated for continuous current with a fixed long-time and instantaneous trip function. The breaker is non-interchangeable and designed for HID applications. Optional accessories such as auxiliary contacts and shunt trip units can be integrated for enhanced control and monitoring capabilities. Manufactured by ABB Electrification, the THQB32015 is built for demanding electrical environments where reliability and space efficiency are critical.
