Abb tmqc22060mm 60A 2P Molded Case Circuit Breaker

Product Description

The ABB tmqc22060mm is a 60-amp, 2-pole molded case circuit breaker (MCCB) designed for thermal-magnetic overcurrent protection in single-phase electrical distribution systems. Rated at 42 kAIC at 120/240VAC, it uses a fixed thermal and fixed magnetic trip mechanism with Long-Time and Instantaneous (LI) trip functions. The bolt-on mounting style and non-interchangeable, common-trip design make it suitable for group metering installations where consistent performance and code compliance are required. Licensed electricians install this breaker as part of meter stack assemblies in multi-family residential and light commercial projects. It accepts 14 AWG through 1/0 AWG copper or aluminum conductors.

The tmqc22060mm is built specifically for use in GE Meter Mod III modular metering stacks. Its MM suffix indicates that a mounting kit is included, compatible with 125-amp or 200-amp single-phase residential meter sockets. This makes it a direct fit for multi-family residential metering applications and light commercial group metering panels where modular, bolt-on breakers are required. The TMQC series is designed to drop into Meter Mod III stacks without additional hardware beyond what is included.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the metering stack and verify absence of voltage before installing or removing the breaker. Ensure conductor sizes are within the 14 AWG to 1/0 AWG range and that terminations are torqued per the panel or stack manufacturer instructions. Do not use this breaker in applications requiring an adjustable or interchangeable trip unit.
