AC power contactor LS Electric MC-185a 400VAC 2a2b MC-185A 400VAC 2A2B

AC Power Contactor – Reliability in Automation and Power Distribution

LS Electric power contactors are components widely used in automation systems and power distribution systems. Model MC-185A, designed to operate at 400VAC and with a rated current determined by the circuit design, is a solid solution for demanding applications.

Characteristics and application

This contactor, designated as MC-185A 400VAC 2a2b, is distinguished by its versatility thanks to the possibility of powering the coil with both AC and DC voltage. The 2a2b auxiliary contact configuration (two normally open and two normally closed contacts) provides flexibility in building control circuits. This makes this contactor suitable for various industrial applications, from motor control to switching heating loads. It is worth noting that the availability of a removable AC/DC electronic coil for 185A models makes it easier to adapt to different working conditions and installer preferences.

Advantages and benefits

• Versatility: The ability to power the coil with both direct current (DC) and alternating current (AC) increases the range of applications.
• Flexibility: The 2a2b auxiliary contact configuration allows for the implementation of complex control circuits.
• Reliability: LS Electric contactors are characterized by high quality workmanship, which translates into long life and trouble-free operation.
• Standardization: Standardized dimensions facilitate mounting and replacement in existing installations.
• Accessories: A wide selection of accessories allows you to adapt the contactor to specific application needs – e.g. modules for switching capacitors.
• Compact size: Allows mounting in tight spaces without losing functionality.
• Durability: Made of high-quality materials, it provides resistance to environmental conditions prevailing in industrial plants.

Construction and mounting

LS Electric MC-185A contactors have been designed with ease of installation and intuitive operation in mind. The solid construction ensures stable operation even in harsh industrial conditions. Thanks to the standardized dimensions, the contactor can be easily mounted on a standard mounting rail or in a control cabinet. The removable coil (available for this model) further facilitates the replacement and maintenance of the device.
