The J7KCR-12-10 DC60 is a magnetic contactor for on/off motor control, rated for a max load current of 5-15A and a max rated load voltage of 200-400 VAC. The coil operates on a 51-56 VDC input, making it suitable for DC control circuits common in industrial panels where a separate 24 VDC supply is not available or where a higher DC rail is used for contactor holding.
Key Ratings and Fit
The 5-15A max load current range covers small motor loads up to about 7.5 kW at 400 VAC (assuming AC-3 duty), so it fits fractional-horsepower pumps, fans, and conveyor drives. The SPST-1N0 auxiliary contact provides a single normally-open feedback signal for PLC status monitoring or interlocking. The 51-56 VDC coil voltage is a tight tolerance window — ensure your control supply delivers at least 51 VDC at the coil terminals under load, factoring in voltage drop across long cable runs or suppression diodes.
Panel Integration
Snap-on DIN rail mounting is standard for this form factor. The contactor occupies a single 45 mm module width, so it fits in a standard 600 mm enclosure with room for a motor-protective circuit breaker and a control transformer on the same rail. Wire the coil from a 48 VDC or 60 VDC supply; the 51-56 VDC range means a 48 V nominal supply may drop below the minimum under load, so size the transformer or DC supply for at least 56 VDC at the contactor terminals.
