MC-1400a

Description

LS Electric Metasol; MC-1400a

High-capacity 3-pole contactor rated ~1,400 A (AC-3), available with wide-range coils AC100–240 V / DC100–220 V (50/60 Hz) and 2 NO + 2 NC auxiliary contacts; built for main feeders and very large motor starters.

The Polar Energy Assessment:

This is heavy-power hardware for plants that mean business. MC-1400a delivers large continuous current handling and arc control features (sealed chambers, high impulse withstand). Use it where busbar termination, mechanical anchoring and detailed protection coordination are in the spec.

Pros

• Very high continuous rating (~1,400 A); suitable for large feeders and motor banks.
• Universal wide-band coil (AC100–240 / DC100–220) simplifies inventory.
• Robust arc management and accessory options for industrial use.

Limitations

• Very large and heavy; needs bolt mounting, busbars and mechanical support.
• Upstream protection coordination is mandatory at this scale (fuses, breakers, relays).
• High cost and heavy installation overhead vs smaller contactors.

Typical use cases

• Main motor feeders in heavy industry (large compressors, pumps, mills).
• Primary switching in energy systems, large UPS/generator interfaces.

Renewable plant switching or plant mains where 1 kA+ contactors are required.
