Overview

The ABB THQB2130 is a 30 Amp double pole bolt-on circuit breaker designed for direct mounting to the bus connections of load centers and lighting panels. Part of ABB’s Q Line series, this thermal-magnetic breaker features a one-inch wide per pole design, ensuring compact integration into residential and commercial electrical systems. The THQB2130 is UL listed for HACR (heating, air conditioning, and refrigeration) applications, making it ideal for protecting HVAC systems, refrigeration units, and other high-demand equipment. Key specifications include a 10,000 AIC (Ampere Interrupting Capacity) rating for reliable operation under fault conditions, and compatibility with 120/240V AC systems. The breaker is designed for branch circuit protection in 208Y/120V AC systems, particularly when used with AQ panelboards. Its internal common trip bar ensures simultaneous disconnection of both poles during overcurrent conditions, preventing partial trips and enhancing system safety. The THQB2130 incorporates a quick-make/quick-break mechanism for consistent operation and easy-to-spot trip indication for rapid diagnostics. Available in 1, 2, and 3 pole versions, this breaker can be ordered with auxiliary contact and shunt trip accessories, and is suitable for HID applications. With a current rating of 30 Amps and bolt-on mounting type, it simplifies installation and replacement, reducing downtime in critical applications. Built to meet UL 489 standards, the THQB2130 delivers dependable overcurrent protection with minimal maintenance requirements in control panels, distribution boards, and building automation systems.
