AC power contactor LS Electric MC-18b 110VAC 1a1b MC-18B 110VAC 1A1B

AC power contactor LS Electric MC-18b – reliability in automation and power distribution.

The LS Electric MC-18b power contactor is a component designed for wide use in automation systems and efficient power distribution. This model, with a coil voltage of 110VAC and a contact configuration of 1a1b, combines a solid construction with compact dimensions, making it an ideal solution for both professional installers and end users. Its versatility allows for mounting on a DIN rail or directly on a panel.

Construction and application

The MC-18b contactor belongs to the METASOL series, characterized by standardized dimensions and high-quality workmanship. It is designed to work with loads with a maximum current of 18A and a maximum motor power of 7.5kW. The 1a1b contact configuration (one normally open and one normally closed contact) provides flexibility in controlling various circuits. Thanks to this, auxiliary contacts are standardly available, which simplifies the design of control systems. The possibility of mounting on a DIN rail or directly on a panel increases its adaptability to different installation conditions.

Key features and benefits

• Wide range of applications: Ideal for controlling motors, heaters and other electrical loads in industry, construction and commercial applications.
