3-pole contactor rated 22 A (AC-3); typically supplied with 1 NO + 1 NC auxiliary and available in common coil voltages (AC and DC). Compact and DIN-rail friendly.

The Polar Energy Assessment:

MC-22b is the everyday small contactor for light motor drives and control duties. It’s often used as a direct replacement for older GMC-22 style parts due to matching dimensions and mounting, making retrofit painless. Good choice when you want a compact, reliable contactor for low currents.

Pros

• Compact 22 A rating with common coil options, easy to source and replace.
• Direct replacement footprint for legacy GMC-22 in many SKUs.

Limitations

• Not suitable for medium/heavy motors, rated for small motors only.
• Limited built-in auxiliaries (1a1b common); add modules if more contacts needed.

Typical use cases

• Small motor starters (fans, small pumps).
• Automation racks and compact control cabinets.
• OEM automation with compact 4-pole wiring requirements.
