MC-150a/4

Description

LS Electric Metasol – MC-150a/4

4-pole magnetic contactor in the Metasol family rated ≈150 A (AC-3), supplied in screw/lug terminal options and available with wide coil bands (example: AC100–240 V / DC100–220 V for “free-voltage” variants). Ideal where neutral must be switched or 4-pole control is required.

The Polar Energy Assessment:

Practical 4-pole workhorse; gives neutral switching without jumping to a much larger frame. Keeps the Metasol accessory ecosystem (auxiliary blocks, overload mounts). Well suited for mid-power panels that must isolate neutral or use 4-pole layouts. Verify PN for terminal style and coil band.

Pros

• Neutral switching (4P) – meets installations that require it.
• Available wide-band coils (AC/DC) reduces SKUs for global stock.
• Direct mount overload & accessory support (Metasol).

Limitations

• Still ~150 A class – not for high-current mains.
• IP20 standard
• 4P dims/weight larger – check PN drawing for panel planning.

Typical use cases

• 3-phase + neutral loads (heaters, certain motor wiring) needing neutral isolation.
• Changeover / transfer panels where extra pole simplifies wiring.
• OEM or retrofit panels requiring a compact 4-pole contactor.
