Description

LS Electric MC-9b (Metasol Series)

LS Electric Metasol MC-9b; small-frame 3-pole contactor variant, often supplied with 1 NO + 1 NC auxiliary. 3-pole magnetic contactor rated approximately 9 A AC-3, with screw terminals, DIN-rail or panel mounting, and available in common coil voltages including AC and DC.

The Polar Energy Assessment:

MC-9b is an alternative small-frame contactor with similar electrical duty to MC-9a but with specific terminal or auxiliary layouts that may better suit retrofit or OEM footprints. Confirm PN to match auxiliary arrangement and coil band.

Pros

  • Compact and easy to wire in tight panels.
  • Often supplied with 1 NO + 1 NC auxiliary for straightforward control wiring.

Limitations

  • Limited to low-current motor duties and loads, not suitable for larger loads.
  • IP20 standard, use enclosure if environment requires.

Typical use cases

  • Small motor starters and control circuits.
  • Retrofit replacements where MC-9b footprint matches older parts.
