MC-1260a

Description

LS Electric Metasol; MC-1260a (AC100–240V/DC100–220V Coil, 2a2b Aux)

A robust, heavy-frame contactor engineered for high-power three-phase systems up to 1260 A. The MC-1260a offers high breaking capacity, arc-resistant chambers, and modular terminals suited for copper-bar or lug termination.

The Polar Energy Assessment:

This isn’t panel candy; it’s for serious power distribution and motor-control work. The MC-1260a combines LS Electric’s standard Metasol design with the contact reliability, arc-quenching, and coil endurance demanded by continuous-duty industrial loads. With proper upstream protection and thermal coordination, it can handle motor feeders, capacitor banks, and heavy compressors without breaking a sweat.

Pros

• Rated 1260 A (AC-3); ideal for large-frame motors, MCCs, and power feeders.
• Universal coil (AC100–240 V / DC100–220 V) simplifies stock and wiring.
• Arc-chamber design extends electrical life and improves safety under high-current switching.
• Compatible with LS accessories; mechanical interlocks, thermal overloads, auxiliary blocks.

Limitations

• Extremely heavy (≈ 35 kg+); requires fixed panel or frame mount.
• Bolt mount only.
• Noise and coil inrush at startup; design around control-circuit loading.

Typical use cases

• Main feeders or large-motor starters in heavy industrial MCCs.
• Power switching for chillers, compressors, or pump stations.
• Backup generator transfer and large-scale HVAC or energy systems.
• Busbar-based distribution panels requiring 1 kA+ contactors.
