MC-1700a

Description

LS Electric Metasol – MC-150a/4

High-capacity 3-pole contactor rated ≈1,700 A (AC-3 class in vendor listings), offered with wide coil bands (AC100–240 V / DC100–220 V) and industrial lug/bar terminations; for plant mains, large motor banks and power switching.

The Polar Energy Assessment:

True heavy power hardware; built for large feeders where busbar termination, arc control and long electrical life are required. Not compact, not casual; choose MC-1700a when you need kA-class switching and proven accessory options. Verify mounting layout and protection coordination carefully.

Pros

• Very high continuous rating (~1,700 A); suitable for very large motors and feeders.
• Wide coil band (AC/DC) simplifies inventory across regions.
• 2a2b auxiliaries for control/feedback built into many SKUs.

Limitations

• Massive, heavy, requires busbar/lug planning and mechanical support.
• Installation and protection coordination are non-negotiable at this level.
• High cost and service overhead vs smaller frames.

Typical use cases

• Plant mains, large compressor/chiller starters, utility-grade switching.
• Renewable plant primary switching and battery/inverter large-current control.
• Busbar distribution where mechanical and electrical robustness is essential.
