AC power contactor LS Electric MC-9b 500VAC 1a1b MC-9B 500VAC 1A1B

AC power contactor LS Electric MC-9b – reliability in automation and power distribution

The LS Electric MC-9b contactor is a component that will find application in a wide range of automation and power distribution systems. Designed for reliability and durability, it is a solid element of the electrical installation. Its construction based on proven solutions guarantees effective circuit switching.

Characteristics and application

This 3-pole contactor, with a rated voltage of 690V, is adapted to work at a frequency of 50/60Hz. It provides effective protection of the circuit against overload and short circuit - like most circuit breakers in this class. Adapted for frequent switching, it withstands up to 15 million mechanical cycles and 2.5 million electrical cycles. This makes it ideal for applications requiring a high frequency of switching on and off.

The MC-9b contactor allows you to control motors with a power of up to 4kW at a voltage of 380/440V and 2.5kW at a voltage of 200/240V (AC-3). It can also be used in power supply systems for resistive devices (AC-1) with a rated current of up to 25A. It has a standard 1a1b auxiliary contact, which facilitates integration with control systems.

Advantages and benefits

• Versatility: A wide range of AC and DC coil voltages allows you to adapt the contactor to different installation configurations.
• Durability: High quality workmanship and standardized dimensions ensure long-lasting and trouble-free operation.
• Efficiency: Adapted for frequent switching, ideal for applications requiring a large number of work cycles.
• Safety: Provides effective circuit protection against overload and short circuit thanks to high impulse resistance (6kV).
• Ease of integration: Standard 1a1b auxiliary contact facilitates connection to control systems.
• Wide range of applications: The ability to control motors of various powers and resistive devices makes it a universal solution for many industries.
