Air contactor CEM25.00-42V-50/60HZ 004645105

Air contactor – a reliable element of electrical installation

This CEM25.00-42V-50/60HZ air contactor is a solid solution for remote switching on and off of motors and other electrical loads. Designed to operate in AC systems, it provides efficient control of loads up to 11 kW at 400 V. It will work both in simple applications and in more advanced switching systems, star-delta or reversing.

Construction and application

This contactor is characterized by its versatility – it can be mounted both on a TH35 rail and on a mounting plate. This makes it easy to adapt to existing infrastructure. The AC-3 rated current of 25 A and the AC-1 current of 45 A guarantee reliable operation even under higher loads. The control voltage of 42 V AC (50/60 Hz) ensures compatibility with commonly used control systems.

An additional advantage is the possibility of connecting an overload relay from the RE series, which allows for effective protection of the motor against overload. The possibility of installing front and side auxiliary contacts enables signaling of the contactor's operating status, which is particularly important in applications requiring monitoring. The BLIME mechanical lock allows for connecting contactors of different sizes, which facilitates expansion and modification of the installation.
