AC power contactor LS Electric MC-40a/4 230VAC MC-40A/4 230VAC

LS Electric power contactor – reliable circuit control

This three-pole LS Electric MC-40a/4 power contactor with a 230VAC coil is a solid solution for controlling motors and other loads in industrial and construction installations. It provides reliable switching of circuits, and its construction guarantees long-term and trouble-free operation. A rated current of 40A and a power of up to 18.5kW make it a versatile element in many applications.

Construction and application

The MC-40a/4 contactor is designed to operate at 230VAC and has a standard configuration of auxiliary contacts 1a1b (one normally open and one normally closed contact). This allows easy connection of additional signaling or control devices. The wide range of applications includes controlling electric motors, lighting, heating systems and other devices requiring remote switching. Thanks to its standardized dimensions, the contactor can be easily mounted in standard distribution boards.

Key features and benefits

• High reliability: The contactor's construction based on high-quality materials ensures long-term and trouble-free operation even in demanding conditions.
• Wide voltage range: Availability of AC and DC coils allows you to match the contactor to different control systems.
• Compact dimensions: It takes up little space in the distribution board, which is particularly important in applications with limited space. The dimensions are 69 x 83 x 94.5 mm, and the weight is only 0.59 kg.
• Easy installation: Possibility of mounting on a DIN rail or on a panel facilitates installation and maintenance.
• Standard auxiliary contacts: 1a1b configuration provides flexibility in connecting additional signaling or control devices.
• Durability: Mechanical endurance at 15 million operations and electrical endurance at 1 million operations guarantees a long service life.
• Compliance with standards: Meets the requirements of IEC60947-1, which confirms safety and quality of workmanship.
• Resistance to working conditions: The rated impulse withstand voltage Uimp is as high as 6kV, and the rated insulation voltage Ui is 690V, which provides protection against overvoltage and damage.

The MC-40a/4 contactor is an optimal choice for professionals and customers looking for a reliable solution for controlling electrical circuits of medium power. Its solid construction, ease of installation and wide range of applications make it an investment that pays off.
