Overview

The ABB Electrification THHQB1160 is a 1-pole, 60 Amp bolt-on circuit breaker from the Q Line series, designed for reliable overcurrent protection in residential and commercial electrical systems. This compact, 1-inch wide per pole device is specifically engineered for secure attachment to the bus connections of load centers and lighting panels, ensuring a stable electrical interface. The THHQB1160 utilizes a thermal-magnetic trip mechanism for effective protection against sustained overloads and short circuits, combining bimetallic strip thermal sensing with magnetic instantaneous tripping for precise response to fault conditions. Key operational features include the Quick-make / Quick-break mechanism for rapid and decisive contact operation, which minimizes arcing and extends breaker life, and an easily visible trip indication for straightforward troubleshooting and enhanced safety. This model operates at 120/240 Vac and has an AIC rating of 22,000, providing robust fault current interruption capability. The Q Line series offers versatility, with options for auxiliary contact and shunt trip accessories to support remote monitoring and controlled shutdown, and suitability for High-Intensity Discharge (HID) applications where stable performance under inductive loads is required. The THHQB1160 is a direct replacement for THQL breakers and is manufactured in the USA, ensuring compatibility with existing ABB load centers and panels. Its design incorporates common trip bars for multi-pole applications to maintain coordinated protection, and the bolt-on mounting system provides a secure, vibration-resistant connection to the bus bar. The breaker is part of ABB’s Q Line series, which is UL 489 listed and meets stringent safety and performance standards for branch circuit protection in both residential and commercial installations. ABB Part Number: THHQB1160. SKU: THHQB1160. UNSPSC Code: 39121601.
