MC-330a/4

Description

LS Electric Metasol – MC-330a/4

4-pole contactor rated ≈330 A per pole (vendor 4P SKUs list current and coil options), with built-in auxiliaries (2a2b typical) and screw terminals for busbar/lug terminations.

The Polar Energy Assessment:

When neutral switching or a 4th pole is required at the 330 A scale, this is the right family. Behavior and ratings align with the 3P MC-330a, but check dimensional/terminal drawing for 4P mounting and busbar clearances.

Pros

• 4P for neutral/isolation at 330 A; useful in power panels.

Limitations

• Larger and heavier; needs mechanical planning and protection coordination.

Typical use cases

• Mains or feeders requiring neutral switching at ~330 A.
• Large multi-motor panels where 4P simplifies wiring and safety logic.
