Abb THQLRK1 125 Amp Main Breaker Retrofit Kit

Product Description

The ABB THQLRK1 is a main breaker retrofit kit rated for 125 amps, designed to add or replace a main breaker in compatible residential load centers. This kit allows electricians to convert a main lug panel into a main breaker panel or restore main disconnect functionality without replacing the entire enclosure. The 125-amp rating makes it suitable for standard residential service entrances. Installation requires the panel to be de-energized and is performed by a licensed electrician following applicable NEC requirements.

This retrofit kit is intended for residential electrical distribution applications. It is typically installed in single-family homes and light residential construction where a main disconnect is required at the load center. The kit is designed to integrate with compatible ABB load center enclosures as a factory-style replacement or upgrade component.

Key Features

• 125-amp main breaker rating for residential service entrance applications

Compatibility

Designed as an OEM-style retrofit kit for compatible ABB residential load center panels requiring a 125-amp main breaker. Consult ABB documentation to confirm compatibility with the specific load center enclosure before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and confirm the service conductors are isolated at the utility meter before beginning work. Do not attempt installation with the service entrance conductors live. Follow the manufacturer installation instructions included with the kit for correct seating and torque of the breaker into the load center.
