MC-400a

Description

LS Electric Metasol – MC-400a

3-pole magnetic contactor rated ≈400 A (AC-3) with factory common auxiliary arrangement 2 NO + 2 NC and wide coil band options (AC100–240 V / DC100–220 V available). Suitable for larger motor feeders and panel distribution duties.

The Polar Energy Assessment:

MC-400a sits where panel practicality meets serious power. It gives you enough continuous capacity for sizable motors without moving into the thousand-amp monster class. It’s robust, accessory-friendly, and intended for bolt/busbar terminations; still IP20 by default, so don’t forget the enclosure.

Pros

• 400 A AC-3 rating for heavy small-motor feeders and panel switching.
• Common wide-band coils (AC100–240 / DC100–220) reduce SKU variety. Accessory ecosystem (auxiliary blocks, interlocks, overload mounts).

Limitations

• Large and heavy; needs busbar/lug planning and bolt mounting.
• IP20; enclosure recommended for industrial dirty/wet sites.
• Verify exact PN for terminal style and aux config before ordering.

Typical use cases

• Large pump/compressor motor feeders.
• Panel feeders and OEM equipment needing 400 A switching.
