The ABB THQL1160 is a single-pole circuit breaker rated at 60 amps, designed to protect branch circuits in residential and light commercial electrical panels. It provides overcurrent and short-circuit protection by interrupting the circuit when current exceeds the rated threshold. The THQL1160 is built to fit standard load centers that accept THQL-series breakers, making it a direct-fit option for panel upgrades, service calls, and new construction work. Licensed electricians install this breaker as part of branch circuit work governed by National Electrical Code requirements.
This breaker is suited for single-pole branch circuit applications in residential load centers and light commercial distribution panels. Typical installations include circuits feeding lighting, receptacles, small appliances, and other 120-volt loads. The THQL1160 is a common replacement and expansion breaker for panels designed to accept the THQL footprint. It handles loads where a 60-amp single-pole breaker is required per the branch circuit design.
Designed as an OEM-style replacement and expansion breaker for load centers and distribution panels that accept THQL-series single-pole circuit breakers.
Installation must be performed by a licensed electrician in accordance with the National Electrical Code and all applicable local codes. De-energize the panel and verify the main breaker is off before handling any bus bar connections or installing the breaker. Confirm the panel is rated to accept THQL-series breakers before installation. Do not exceed the panel's maximum breaker count or bus bar ampacity.
