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.

Compatibility

Designed for use with GE Meter Mod III modular metering stacks. The included mounting kit is compatible with 125-amp and 200-amp single-phase residential meter sockets.

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.
