Description
The ABB / GE THQB32030 (Catalog Number: THQB32030, UPC: 783164012415) is a compact, 3-pole thermal-magnetic miniature circuit breaker engineered for residential, commercial, and industrial electrical distribution systems. Rated for 30 Amps at up to 240 VAC, this bolt-on Q-Line breaker provides reliable overload and short-circuit protection with an interrupting capacity of 10 kAIC.
Featuring a standard one-inch wide per pole design, the THQB32030 incorporates a quick-make / quick-break mechanism, an internal common trip bar to prevent single-phasing, and an easy-to-spot trip indication for enhanced safety. It is HACR rated and suitable for reverse feed applications, making it ideal for 3-phase load centers and lighting panelboards.
Key Features
- Three-Pole Thermal-Magnetic Protection: Combines thermal overload sensing with magnetic short-circuit tripping across 3 poles for comprehensive system protection.
- 30A / 240V Rating: Engineered for 3-phase branch circuit protection up to 240 VAC (120V, 120/240V, or 240V systems).
- 10 kAIC Interrupting Capacity: Provides reliable fault-clearing capacity at 120V, 120/240V, and 240V AC.
- Bolt-On Configuration: Designed for secure bolt-on connection directly to the bus bars of compatible load centers and lighting panels.
- HACR Rated & Reverse Feed Capable: Certified for heating, air conditioning, and refrigeration equipment, and approved for reverse feed installations.
