Application
Switching relays are used in control systems as coupling relays or for the electrical or safe isolation of electrical circuits.
Safe Isolation
The magnet coil and the contacts meet the requirements for the safe isolation of the safety extra-low voltage (SELV) of the magnet coil from the operating voltage of the contacts.
Functional Test Using the Manual Switch
Switching relays have a manual switch that shows the switching position. The manual switch allows manual actuation of the switching relay; this allows the devices and control functions to be tested.
