5TT5 7 Insta contactors, DC technology
Insta contactors are standard devices in installation technology and belong to the BETA switching device range. Insta contactors are particularly suitable for switching heating, lighting and motors.
While Insta contactors have seen a considerable decline in use in the electrical heating sector in residential buildings, they are playing an increasingly significant role in building lighting circuits. Insta contactors are also increasingly used in industry for motors where distribution technology plays a major role, e.g. in auxiliary installations for heat pumps and air conditioning technology.
In addition to their basic function, they can also be used to switch single-phase and three-phase electrical motors on and off. The 5TT5 7 Insta contactors meet the requirements of EN 60947 and are approved to UL 508.
