Abb thqlrk2 Main Breaker Retainer 6-8 Circuit

Product Description

The ABB thqlrk2 is a field-installed main breaker retainer designed for use with PowerMark Gold load centers. It physically secures the main breaker in place within the panel, providing a positive retention point that keeps the breaker properly seated during operation and service. Licensed electricians install this accessory during new panel builds or retrofits where a retainer is required by code or panel design. It is compatible with THQL-series circuit breakers installed in 6 to 8 circuit PowerMark Gold load centers.

This retainer is intended for residential and light commercial electrical distribution panels. It fits load centers in the PowerMark Gold line when configured with 6 to 8 circuits. The retainer is a field-installed accessory, meaning it can be added to an existing compatible load center without replacing the panel enclosure or main breaker assembly. It is suited for panels where the main breaker requires mechanical retention beyond the standard clip or tab arrangement.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the absence of voltage before working inside the load center. Follow the panel manufacturer's installation instructions for proper retainer placement and seating. Do not force the retainer into position, as improper fit may indicate an incompatible breaker or panel configuration.
