MC-500a

Description

LS Electric Metasol – MC-500a

3-pole magnetic contactor rated ≈400 A (AC-3) with factory common auxiliary arrangement 2 NO + 2 NC and wide coil band options (AC100–240 V / DC100–220 V available). Suitable for larger motor feeders and panel distribution duties.

The Polar Energy Assessment:

MC-500a is the sensible step into larger panel work; high continuous current, accessory flexibility and standard Metasol protections. Expect heavy lug/busbar terminations and a need for careful upstream protection coordination.

Pros

• 500 A AC-3 rating for larger motors and feeders.
• Available AC/DC coil band SKUs — global control compatibility.
• Standard accessory support (overloads, auxiliaries).

Limitations

• Requires substantial panel space, lugging and mechanical support.
• IP20; enclosure recommended for industrial dirty/wet sites.
• Verify exact PN for terminal style and aux config before ordering.

Typical use cases

• Medium/large motor feeders and plant distribution.
• Panel feeders and OEM equipment needing 500 A switching.
