Abb THQL1150 Single Pole Circuit Breaker 50A 120/240V

Product Description

The ABB THQL1150 is a single-pole circuit breaker rated for 120/240 volt residential and light commercial electrical panels. It provides overcurrent protection by interrupting the circuit when current exceeds the rated amperage, protecting wiring and connected equipment from damage due to overloads and short circuits. The THQL series is a standard load-center breaker format widely used in residential distribution panels. Licensed electricians and qualified electrical contractors install this breaker as part of branch circuit protection work in both new construction and service upgrade applications.

The THQL1150 is suited for single-pole branch circuit applications in residential and light commercial settings. It fits standard load centers designed to accept THQL-type breakers. Typical installations include circuits for lighting, receptacles, and small appliances requiring a 50 amp single-pole breaker at 120 or 240 volts.

Key Features

• Single-pole configuration for standard branch circuit protection
• Rated 50 amps for appropriate overcurrent protection
• 120/240 volt rating suits common residential panel voltages
• THQL series format for compatibility with matching load centers
• Thermal-magnetic trip mechanism for overload and short circuit protection

Compatibility

Designed as an OEM-style replacement or new-installation single-pole circuit breaker for load centers and distribution panels that accept THQL-series breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the main breaker and verify the panel is de-energized before handling any breaker or bus bar connections. Do not exceed the breaker ampacity rating for the connected circuit wiring. Verify load center compatibility before installation.
