Abb THQC2150WL Circuit Breaker 1 Pole 50 Amp

Product Description

The ABB THQC2150WL is a single-pole circuit breaker designed for overcurrent protection in residential and light commercial electrical distribution systems. It provides reliable branch circuit protection by interrupting current flow when an overload or short-circuit condition is detected. Licensed electricians install this type of breaker in load centers and panelboards as part of standard branch circuit wiring. The THQC series is built to ABB quality standards for use in compatible load center enclosures.

This breaker is suited for residential panel installations and light commercial applications where single-pole branch circuit protection is required. It fits into load centers that accept THQC-style breakers, making it a practical replacement or new-installation component for electricians working on service upgrades, circuit additions, or panel repairs.

Key Features

• Single-pole configuration for standard branch circuit protection
• THQC series design for compatibility with matching load center enclosures

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements. Always shut off main panel power and verify the bus is de-energized before installing or replacing a breaker. Confirm the load center is rated to accept THQC-style breakers before installation.
