Silent contactor 230VAC 2NO+2NC 25A AC-7a/b ESC427S

Silent contactor for a wide range of applications

This silent 230VAC contactor with a 2NO+2NC configuration and a current of 25A is a reliable solution for controlling various circuits. It will work well in both home and commercial installations, offering efficient and safe switching of loads. The contactor's design minimizes noise during operation, which is especially important in residential or office spaces.

Functionality and application

This contactor is designed to control lighting, heating, ventilation circuits, and as an actuator in control systems. Thanks to the AC-7a/b usage category, it is suitable for handling both resistive (e.g., light bulbs) and inductive loads (e.g., motors). The ability to connect an additional auxiliary contact ESC080 expands the functionality of the device, enabling the implementation of more complex control schemes. The quiet operation of the contactor is a big plus – it reduces acoustic disturbances in the environment.

Characteristics and mounting

The contactor occupies 2 module widths, making it easy to mount in electrical distribution boards. The cross-section of flexible wires is 1-6 mm², and rigid wires is 1-10 mm². The rated operating voltage is 400V, and the control voltage is 230V AC. The IP2X degree of protection provides basic protection against touching and the ingress of solid objects. Mechanical durability at 100,000 cycles and electrical durability at 30,000 cycles guarantee long and trouble-free operation of the device. Low energy consumption translates into operational savings – up to 30% less energy consumption by devices connected to the contactor.
