LS Electric MC‑1260A Contactor 1260A 2a2b AC100‑240V/DC100‑220V 50/60Hz

Description

LS Electric MC‑1260A Contactor 1260A 2a2b AC100‑240V/DC100‑220V 50/60Hz

Heavy-duty 3-pole magnetic contactor rated for 1,260 A (AC-3) switching, with built-in auxiliary contacts (2 NO + 2 NC) and wide-range coil options: AC 100–240 V (50/60 Hz) and DC 100–220 V — intended for large motor and power-switching applications (solar, wind, heavy industrial).

The Polar Energy Assessment:

This is a true power contactor — not a garden-variety panel part. MC-1260A uses sealed arc-chambers and one-mold construction to handle high AC-1/AC-3 loads and offer long electrical life. It’s aimed at medium-to-large power systems (renewables, large motor starters, main feeders) where high continuous current capacity and wide coil flexibility matter. If you need compactness, this won’t win; if you need uptime and raw current, it will.

Pros

• Very high rated current (1,260 A); suitable for large motor feeders and power switching.
• Wide coil voltage support (AC100–240V / DC100–220V); fits many global control schemes.
• Sealed arc-chamber / optimized AC-1 control design; longer life and better switching performance on heavy loads.

Limitations

• Physically large and heavy — requires serious panel space and mounting provisions.
• Installation/auxiliary wiring is more complex than small-frame contactors; plan terminal / luging.
• Not a plug-and-play replacement for smaller starters — coordinate protection (breakers, relays) carefully.

Typical use cases

• Main motor feeder for large industrial motors and multi-motor systems (pumps, compressors).
• Power switching in renewable installations (wind/solar inverter/load control).
• Utility / plant main breakers/contactors where DC control buses are used for remote control.
