DC power contactor LS Electric MC-18b 48VDC 1a1b MC-18B 48VDC 1A1B

DC Power Contactor – Reliability in Automation and Power Distribution

This LS Electric MC-18b 48VDC 1a1b power contactor is a robust component designed for use in automation systems and power distribution applications. It is suitable for both industrial installations and more demanding applications. Its construction ensures reliability and long life, which translates to minimizing downtime and reducing operating costs.

Construction and application

The MC-18b contactor is made of high-quality materials, guaranteeing its durability even in harsh working conditions. It has a 1a1b contact configuration (NO + NC), which means one normally open and one normally closed contact. This solution allows for flexible use in various control circuits. DIN rail or panel mounting simplifies integration with existing infrastructure. A width of 45mm and a height of 73.5mm allow for compact solutions.

Key features and benefits

• Suitable for 48V DC voltage: Ideal for powering devices operating on direct current, such as DC motors, solenoids or valves.
• Rated current 18A: Allows controlling loads with a power of up to 7.5kW, making it a versatile solution for many applications.
• 1a1b contact configuration: Provides flexibility in control circuit design – the ability to switch circuits on and off and signal status.
• Compact dimensions: Facilitate mounting in tight spaces, optimizing the use of space in control cabinets.
• Protection class IP20: Protects against finger contact and the ingress of solid objects larger than 12.5mm – standard protection for devices mounted inside control cabinets.
• Wide operating temperature range (-5…60°C): Allows operation in various environmental conditions without the risk of damage to the device.
• Solid screw connections: Ensure safe and durable connection of power and control wires.

This contactor is not just a component connecting circuits – it is an investment in the reliability and safety of your electrical installation. Its solid construction and well-thought-out solutions make it a trusted choice for both professionals and end users.
