Contactor 230VAC 4NC 40A AC-7a/b ESC441

Universal contactor for domestic and industrial applications

This 230VAC, 40A contactor with four normally open contacts (4NC) is a reliable solution for controlling loads in electrical installations. It is suitable for both residential and industrial environments where frequent switching of circuits is required. The contactor design allows for efficient switching of various types of loads, from lighting to heating appliances.

Characteristics and application

The ESC441 contactor is designed to operate with a control voltage of 230V AC, making it compatible with most standard electrical installations. Its switching capacity covers a wide range of loads – incandescent bulbs (up to 4000W), fluorescent lamps (up to 1900VA), and fluorescent lamps with compensation (up to 3000VA with DUO compensation and 1300VA with parallel compensation). This means that a single contactor can handle different types of lighting. Using a contactor allows for remote circuit control, process automation, and increased safety of electrical appliance use.
