Description
LS Electric Metasol – MC-2650a
High-capacity 3-pole magnetic contactor rated 2,650 A (AC-3) (distributor listings show 2650 A), with wide coil band AC100–240 V / DC100–220 V (50/60 Hz) and 2 NO + 2 NC auxiliaries; intended for ultra-heavy feeders and power switching.
The Polar Energy Assessment:
MC-2650a is for plant mains and utility-scale switching. It’s built to be bolted to busbars, withstand arc stress, and operate reliably in high-current live work. Please have in mind that you should coordinate protection, busbar sizing, mechanical mounts and coil control strategy before anything else.
Pros
- Very high continuous capacity (~2,650 A) for major feeders and power systems.
- Wide coil voltage bands (AC/DC); good for global stock and DC control buses.
- 2a2b auxiliaries for control/feedback on common SKUs.
Limitations
- Extremely large, requires bolt mounting and major installation planning.
- Not DIN-rail mountable; requires bolt mounting and busbar lugs.
- Protection coordination and commissioning complexity are high.
Typical use cases
- Plant mains, utility feeders, and multi-MW motor banks.
- Renewable energy plant switching and inverter/battery large-current control.
- Industrial distribution panels where >2 kA switching is needed.
