AC power contactor LS Electric MC-18a/4 230VAC MC-18A/4 230VAC

AC Power Contactor – Reliable Control of Electrical Circuits

LS Electric MC-18a/4 230VAC power contactor is a device designed for the reliable switching of electrical circuits. It is suitable for both industrial automation applications and power distribution installations. Its solid construction and high-quality workmanship guarantee long-lasting and trouble-free operation.

Characteristics and Application

This four-pole contactor, designed to operate with a coil voltage of 230VAC, allows control of loads up to 7.5kW (AC-3). It is a versatile device that can be used to control electric motors, heaters, and other loads requiring frequent switching. Thanks to its compact dimensions (45 x 73.5 x 79mm) and the possibility of mounting on a DIN rail, its installation is simple and convenient. The rated current in category AC-1 is 40A, and in AC-3 – 18A, making it suitable for a wide range of applications.

Advantages and Benefits

• High Reliability: LS Electric contactors are characterized by high quality and durability, which translates into trouble-free operation of installations.
• Versatility: A wide range of AC coil voltages allows you to match the contactor to different power systems.
• Compact Dimensions: Allow mounting in tight spaces and optimizing switchboards.
• Easy Installation: Possibility of mounting on a DIN rail and standard dimensions facilitate installation and replacement.
• Durable Construction: Mechanical endurance of 15 million cycles and electrical endurance of 800 thousand cycles guarantee long device life even with intensive use.
• Wide Range of Applications: Suitable for controlling various types of loads, including motors, heaters and other electrical receivers.
• Standardized Dimensions: Facilitate the replacement of existing contactors from other manufacturers without the need to modify the switchboard.
• High Resistance to Environmental Conditions: Ensures stable operation even in harsh industrial conditions.

Technical Parameters and Construction

The MC-18a/4 contactor has four normally open contacts, providing complete separation of the control circuit from the working circuit. The impulse withstand voltage (Uimp) is 6kV, which guarantees safety in the event of overvoltage. The contactor coil is adapted to operate at a frequency of 50/60Hz, ensuring compatibility with most power grids. Made of high-quality materials, it provides resistance to mechanical damage and corrosion. The weight of the device is only 0.33kg, which facilitates its transport and installation.
