THQB32040 - 40A Circuit Breaker

THQB32040 - 40A Circuit Breaker

The THQB32040 is a 40-amp, 3-pole bolt-on circuit breaker from the THQB Q-Line family. It is rated for 240VAC and features a 10kA interrupting capacity, making it suitable for protecting your three-phase branch circuits in commercial and industrial electrical systems.

This molded case breaker uses a bolt-on mounting design for a secure connection within compatible panelboards. The 3-pole configuration allows it to disconnect all phases simultaneously during an overload or short-circuit condition. Its HACR rating permits use in approved heating, air conditioning, and refrigeration equipment applications.

Commonly found in electrical distribution systems, equipment panels, and facility maintenance projects, the THQB32040 is often used where a 40-amp three-phase breaker is required.
