Eltako MTR12-UC Isolation relay Nominal voltage: 250 V 1 pc(s)

Motor isolating relay. Stand-by loss only 0.5 watts. 1 division unit. The tubular motors of shading elements and roller shutters must never be connected directly in parallel, as otherwise there will be back voltages via the limit switches and ultimately the motors will be destroyed. For one motor and if the control voltage and motor voltage are 230V, a EGS12Z-UC is sufficient. However, if more than one motor is to be controlled with a EGS12Z-UC or if the control voltage is not equal, a MTR12-UC must be connected for each of two motors. The MTR12-UC can be operated in parallel, but requires free contact outputs K2/K3 of the controlling EGS12Z-UC. These are connected to terminals K2/K3 of the MTR12-UC. 1/2 = Engine 1, 3/4 = Engine 2. With a rotary switch, the functions can be locked up or down and can be switched off completely. This lock only applies to the max. 2 connected motors. This allows individual shading elements or shutters to be completely or partially excluded from the automatic function of an overall control.
