LS Electric MC‑1400A Contactor 1400A 2a2b AC100‑240V/DC100‑220V 50/60Hz

Description

Heavy-duty 3-pole magnetic contactor rated for 1,400 A (AC-3) switching, fitted with 2 NO + 2 NC auxiliary contacts and a wide “free-voltage” coil family supporting AC100–240 V and DC100–220 V for global control compatibility. Designed for large motor feeders and power-switching duties in industrial installations.

LS Electric MC‑1400A Contactor 1400A 2a2b AC100‑240V/DC100‑220V 50/60Hz

This is a bona fide power contactor: large physical footprint, heavy terminal/lug requirements, and arc-management features built for high current service. Use it where continuity and mechanical endurance matter — main feeders, large motors, or primary switching in renewable/utility applications. Don’t try to shoehorn it into a small panel; plan busbars, mechanical supports, and protection coordination first.

Pros

• Very high AC-3 rating (1,400 A); suitable for large feeders and heavy motors.
• Wide coil band (AC100–240 V / DC100–220 V); fits many global control schemes and DC control buses.
• Built auxiliary set (2 NO + 2 NC) for control/status feedback and interlocks.

Limitations

• Large, heavy, and requires substantial panel space, lugs, and mechanical support.
• Coil heating and operate/dropout behavior vary across AC/DC bands; verify coil characteristics for your nominal control voltage.
• Upstream protective device coordination (breaker sizing, trip curves) is mandatory at this current level.

Typical use cases

• Main motor feeders for large motors or cluster motor systems (pumps, compressors, large conveyors).
• Primary power switching in renewable installations (solar/wind farms), battery/DC hybrid systems where DC coil control is used.
• Utility or plant mains where a reliable mechanical contactor with auxiliary feedback is required.
