Abb THQP150 Single Pole Circuit Breaker 50A 120/240V

Product Description

The ABB THQP150 is a THQP-series single pole miniature circuit breaker rated for 120/240 volt residential and light commercial panelboard applications. Designed for plug-in installation in compatible load centers, it provides overcurrent and short-circuit protection for branch circuits. The THQP form factor is a half-size design that fits two breakers in a single pole space, making it a practical choice when panel space is limited. Licensed electricians install this breaker during new construction, panel upgrades, and circuit additions.

The THQP150 is suited for residential load centers and light commercial panelboards that accept the THQP plug-in breaker format. Its compact footprint is commonly used in space-constrained panels where full-size breakers cannot be accommodated. Typical applications include branch circuit protection for lighting, receptacle, and small appliance circuits operating at 120 volts or 240 volts single phase.

Key Features

• Single pole configuration for 120/240 volt branch circuit protection
• Half-size THQP form factor fits two breakers in one standard pole space
• Plug-in installation for compatible panelboards
• Provides overcurrent and short-circuit protection per NEC requirements
• 50 amp continuous current rating

Compatibility

Designed as a plug-in replacement for panelboards that accept the THQP-series miniature circuit breaker form factor. Verify load center compatibility before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the main breaker is off before handling any breaker or bus connection. Confirm the target load center accepts the THQP plug-in format prior to installation. Do not exceed the breaker ampere rating for the connected circuit conductors.
