AC power contactor LS Electric MC-50a 42VAC 1a1b MC-50A 42VAC 1A1B

AC power contactor LS Electric MC-50A – a reliable automation component

The LS Electric MC-50A power contactor is a solid solution for automation and power distribution systems, designed for reliability and durability. This 3-pole contactor, with a rated current of 50A (AC-3) and 70A (AC-1), is ideal for controlling motors and other electrical loads. It will work in both industrial applications and more demanding installations.

Construction and mounting

The MC-50A contactor offers flexible mounting – it can be mounted on a DIN rail or directly on a mounting plate. It has screw terminals, which simplifies the connection of wires. Additionally, the contactor's design ensures safe use thanks to protection against accidental contact with live parts. The ability to mount thermal relays directly under the contactor allows you to create a complete motor protection system.

• Control of electric motors (up to 25 HP at 230V and 40 HP at 460V).
• Industrial process automation.
• Electrical switchboards.
• Lighting systems.
• Applications requiring frequent switching of the load.

Characteristics and benefits

The design of the MC-50A contactor has been designed for long-term operation. The use of high-quality materials and precise workmanship guarantee reliable operation even in difficult working conditions. This contactor is also characterized by:

• Compact dimensions, making it easy to mount in limited space.
• Possibility of expansion by mounting additional accessories, such as thermal relays or auxiliary contact modules.
• Compliance with applicable safety standards.
• High resistance to electromagnetic interference.
