ETI's RA series of modular contactors are designed for remote control and automatic monitoring of electrical devices and equipment in both industrial and residential applications. They are effectively used in lighting, heating, and ventilation systems, as well as for switching low-power motors. They feature a modular design (1, 2, or 3 modules), which ensures easy mounting on a DIN rail.
The series covers rated currents from 20 A to 63 A and a coil control voltage of 230 V AC. Thanks to their low power consumption, high switching speed, and the option to use additional contact blocks, these contactors are suitable for a wide range of applications.
