AC power contactor LS Electric MC-22b 400VAC 1a1b MC-22B 400VAC 1A1B

AC Power Contactor – Reliable Circuit Control

This LS Electric MC-22b power contactor is a component that will find application in a wide range of electrical installations, both in industrial automation and in energy distribution systems. Designed to operate at 400VAC, it offers solid and efficient circuit switching. Its construction with one main contactor (1a) and one auxiliary contactor (1b) provides flexibility in control circuit configuration.

Characteristics and application

The MC-22b contactor is particularly useful where frequent switching of electrical loads is required. A rated current of 22A (AC-3) allows control of devices with a power of up to 11kW. The contactor's construction based on LS Electric technology guarantees high reliability and long life, which translates into minimizing downtime and maintenance costs. Thanks to its standard dimensions, it can be easily integrated with existing systems.

Advantages and benefits

• Efficiency: Suitable for operation with loads up to 11kW at 400VAC, making it a universal solution for many applications.
• Reliability: Manufactured by the renowned manufacturer LS Electric, it guarantees stable operation and long life.
• Flexibility: 1a1b contact configuration allows adaptation to different control schemes.
• Ease of integration: Standard dimensions facilitate installation and replacement in existing installations.
• Safety: Provides effective protection of the circuit against overload and short circuit – as with any contactor of this type.
• Compact size: Allows mounting in tight switchgear spaces.
• Wide range of applications: Ideal for controlling motors, heaters and other electrical devices requiring frequent switching.

Additionally, the availability of technical documentation (CE declaration of conformity and technical manual) facilitates proper selection, installation and servicing of the device. The ability to download these documents provides full control over the installation and operation process of the contactor.
