The CMB-Series is the miniature version of Carling’s push-to-reset family of thermal circuit breakers. A simple precision design, which minimizes the number of moving parts, delivers cost-effective performance and reliable protection against shock and vibration, while a consistent trip point over temperatures ranging from -10°C to +60°C makes it suitable for a wide range of equipment applications.

The CMB-Series also offers a variety of hardware options, including indicator plates, plastic or metal hex or ring nuts, as well as clear and black hex boots. Terminal options include .250 QC tabs and screw with or without 90-degree bend or a combination. This miniature thermal breaker is ideally suited for household appliances, power strips and supplies, on/off-highway, medical and audio-visual equipment. Additionally, it offers UL 1500 Ignition Protection for marine grade applications to reduce fire danger.

These single pole breakers have plastic or metal bushing construction.
