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

LS Power Contactors – Reliability and Efficiency in Automation

LS Electric power contactors are components widely used in automation and power distribution systems. Designed for reliability and efficiency, they are a key element in controlling various electrical loads. The MC-400A 400VAC 2a2b model stands out with its solid construction and parameters that meet the requirements of professional installations.

Characteristics and Application

This three-phase contactor, with a rated current of 400A in category AC-3, is designed for frequent switching of electrical loads such as motors, heaters, or ventilation systems. Its construction provides effective protection against overload and short circuit, which translates into safety and long-term operation of the installation. Thanks to the standard equipment with 2a2b auxiliary contacts (two normally open and two normally closed), the contactor enables easy integration with control and signaling systems. The possibility of mounting on a DIN rail or screwing increases the flexibility of the installation.

Advantages and Benefits

• High Reliability: LS Electric contactors are characterized by high quality workmanship and durability, guaranteeing trouble-free operation for a long time.

• Wide Range of Coil Voltages: Availability of coils with different AC and DC voltages allows you to match the contactor to the specific requirements of the installation.

• Versatility: The ability to use in various applications – from motor control to heating systems – makes it a universal solution for many industries.

• Compact Dimensions: Standardized dimensions facilitate mounting and integration with existing systems.

• High Durability: Designed to operate in demanding conditions, it withstands a large number of switching cycles (mechanical: 2,500,000 operations, electrical: 500,000 operations).

• High Power: Designed for loads up to 200kW at 380-400VAC.

• Safety: Provides effective protection of the circuit against overload and short circuit — as with most circuit breakers in this class.
