M-frame Square D molded case circuit breakers are rated up to 800A and 600VAC and interrupt excessive current flows to protect devices from electrical damage. They're used in construction, commercial buildings, oil and gas, and other industrial and commercial applications. Their current-carrying parts, mechanisms, and trip devices are contained in a molded case.
Depending on your application, Square D’s “M” frame might be the right frame for you. It has an amperage rating of 300-1000 amps, which makes it the ideal choice for larger industrial loads. Depending on your needs, the “M” frame has different voltage options that range from 240 vac up to 600 vac. It also has either a 2 or 3 pole configuration. The “M” frame comes in two different designs: lug-to-lug and I-line. A traditional lug-to-lug frame has lugs on both ends while the conventional, I-line, bus-mounted frame has lugs on one end and a crown on the other, which makes installation a breeze.

③Eaton - Cutler Hammer (Westinghouse )Series
④SIEMENS PLC Series，Siemens CNC system
⑤Eaton moller Series
These QOB sereis miniature circuit breakers are bolted into place in NQOD and NQ panelboards or interiors, so they're more stable than plug-in or unit-mount circuit breakers. They interrupt currents when low-level faults are detected in the circuit. They have a lug orientation to allow for straight-in wiring through bus bars, which eliminates the need to pigtail wires and helps organize the load center.
