Modular Contactor IDEAL KMC-63-40 63 A 400 V AC, KMC-63-40

Modular contactor IDEAL KMC-63-40 is a DIN-rail mounted switching device rated for a nominal current of 63 A and designed for use on 400 V AC supply systems. It is intended for installation in distribution boards and electrical panels where compact, modular switching of circuits and motors is required. The product supports remote control of loads and is suitable for applications that require a robust AC contactor with standard modular dimensions.

Advantages

The modular design allows straightforward installation on standard DIN rails and saves panel space compared with larger contactors. With a 63 A nominal rating and compatibility with 400 V AC systems, the device handles medium-duty switching tasks reliably. The contactor is engineered for integration into building and industrial electrical installations and provides clear separation between control and load circuits for safer operation.

Suitable for

• Switching and controlling single-phase and three-phase loads up to 63 A
• Remote control of motors, lighting circuits and heating elements in distribution panels
• Load management and automation systems in residential and commercial buildings
• Replacement or retrofit in modular DIN-rail control assemblies

Key specifications

• Nominal current: 63 A
• Rated voltage: 400 V AC
• Mounting type: DIN-rail modular mounting
• Application: AC switching for motors, resistive and mixed loads
• Form factor: modular contactor suitable for electrical distribution panels

How to use

Install the contactor on a standard DIN rail inside an appropriately rated enclosure, following local electrical regulations. Connect the incoming and outgoing power conductors to the main contacts and wire the control coil according to the control voltage and circuit diagrams. Ensure correct tightening of terminals and verify that the contactor coil voltage matches the control circuit. Perform functional tests with the supply isolated and then under live conditions to confirm correct switching behavior before placing the circuit into regular service.

Usage recommendations

Use the contactor within its specified current and voltage ratings and ensure adequate overcurrent protection and thermal management in the panel. Follow manufacturer installation instructions and applicable electrical codes when integrating the device into motor starters, lighting controls or load management systems.
