Installation Contactor 40A 2NO 240VACGet latest price

If the control current is interrupted, a spring forces the disconnection o return of the contacts to their original position. This design means that contactors ensure a galvanic separation between the control circuit and the switched circuit whilst simultaneously allowing high currents to be switched. Installation contactors are only designed in a limited way for release and must be protected against overload and short-circuits by upstream protective devices. Installation contactors in series HS for installation in distribution boards are extremely quiet and have very low-noise switching processes, are highly versatile thanks to their utilization categories and have a long mechanical and electrical service life. The magnetic coil of this series is suitable for continuous operation (100% duty cycle). Devices in this design are operated with a control voltage of 230 V AC.

• wide range of different contacts, high electrical and mechanical endurance, extremely quiet, suitable auxiliary switch and seal cap available

• quick fastening to mounting rail, any installation position

• Installation contactors are frequently used in residential and purpose-built buildings as well as industrial facilities. They take on the switching of incandescent lamps, fluorescent lamps, transformers for halogen low-voltage lamps, mercury vapour high-pressure lamps (HQL, HPL), metal halide lamps (HQI, HPI), sodium vapour, low and high-pressure lamps, storage heaters or drives (motors).

• The designation for the devices in this series includes both the rated current (first group of digits) and the contact design (final group of digits). A HS 25-31 therefore has a rated current of 25 A, three normally opened contacts and one normally closed contact., At ambient temperatures above 40 °C, we recommend using the RD 05 spacer.
