MC-225a/4

Description

LS Electric Metasol – MC-225a4

4-pole magnetic contactor in the Metasol midframe family rated 225 A (AC-3): designed for switching larger small/medium feeders where neutral switching is required.

The Polar Energy Assessment:

MC-225a/4 sits between small industrial contactors and heavy-frame gear: enough current capacity for significant motors (and feeders) while keeping installation simpler than the kA-class contactors. Useful where neutral isolation is required (4P) and panel space is moderate. Confirm PN for auxiliary config and coil band.

Pros

• 225 A AC-3 rating; handles medium motor/feed applications.
• Common coil bands (AC100-240 / DC options in family) simplify stocking.
• Auxiliary support (typically 2a2b on many MC-225A SKUs).

Limitations

• 4-pole increases width/depth vs 3P variant, check panel layout.
• IP20; enclosure recommended for industrial dirty/wet sites.

Typical use cases

• 3-phase + neutral feeders requiring isolation (heaters, loads with neutral).
• Motor starters and panel feeders in light-to-medium industrial plants.
• OEM panels where 4-pole wiring simplifies protection and safety rules.
