Big Motors Need Big Contactors
Industrial motors above 200kW (270HP) need heavy-duty contactors that can switch the inrush current without welding contacts. Eaton DILM large-frame contactors (400A to 2000A) handle everything from HVAC chillers to mining crushers to data center UPS systems.
RF Mando added 22 new large contactor SKUs to rfmando.com in 2026, covering the complete 400A-2000A range. This guide shows which to stock.
1. The 400A Class: XTCE400-500
For motors 200-300kW (270-400HP). HVAC, water treatment, large pumps:
Bulk price range: $1,200-$1,500 per contactor. Lead time 7-15 days.
2. The 580A-650A Class: XTCE580-650
For motors 315-400kW (420-540HP). Compressors, large fans, marine drives:

Bulk price range: $2,500-$2,800 per contactor.
4. The 1000A-2000A Class: XTCEC10-20
For the largest motors (710-1400kW / 950-1900HP). Power generation, heavy industry, ship propulsion:
Bulk price range: $3,200-$4,500 per contactor. Highest-value inventory in the DILM line.
5. Coil Voltage Variants (A/C/Y/TD)
Each contactor comes in 3-4 coil voltage variants:
- A = 110-250VAC/DC (wide range, most common)
- C = 250-500VAC (high voltage industrial)
- Y = 48-110VAC/DC (low voltage control)
- TD = 24-48VDC (DC coil for battery-backed systems)
Stocking 3 variants (A, C, Y) covers ~90% of B2B customer needs.
