DC power contactor LS Electric MC-40a 110VDC 1a1b MC-40A 110VDC 1A1B

DC contactor for automation and power distribution systems

This LS Electric power contactor from the METASOL series is a reliable component designed for use in automation and power distribution systems. The device's design and parameters allow for effective control of DC circuits, ensuring safety and long-term operation. This is particularly important in applications requiring frequent switching of the load.

Construction and application

The MC-40A 110VDC 1A1B contactor is characterized by a three-pole contact configuration with three normally open (NO) contacts and one normally closed (NC) contact. The 110V DC coil voltage makes it compatible with a wide range of control systems. The operating current of up to 40A allows it to handle various loads, including motors up to 18.5 kW. Panel or DIN rail mounting simplifies integration with existing infrastructure. Screw terminals provide a solid connection of the wires.

Key features and benefits

• Versatility: This contactor finds application in many automation and power distribution systems, thanks to the wide range of coil voltages AC and DC available in the METASOL series.
• Safety: Standardly equipped with 1a1b auxiliary contacts (NO + NC), which increases the functionality and safety of the installation.
• Compact dimensions: Width of 69mm and height of 83mm allow for mounting in limited space.
• Durability: IP20 protection class provides protection against touching and interference caused by small solid particles, which translates into a longer lifespan of the device.
• Wide operating temperature range: The ability to operate at temperatures from -5°C to 60°C guarantees reliability in various environmental conditions.
• Easy installation: Possibility of mounting on both panel and DIN rail facilitates installation and servicing.
