Motor isolating switch, 2+2 NO contacts not potential free 4A/250V AC, for two 230V motors. No standby loss. For installation. 49x51mm, 22mm deep. The connection terminals are plug-in terminals for conductor cross-sections from 0.2mm² to 2.5mm². The MTR is a control switch for controlling one or two blind and roller shutter motors with mechanical or electronic limit switches. The tubular motors of the shading elements and roller shutters must never be connected directly in parallel, otherwise reverse voltages will occur via the limit switches and ultimately the motors will be destroyed. Several MTRs can be connected in parallel at the inputs. For example, EGS12Z, EGS61Z, FSB14, FSB61NP and FJ62NP are suitable for activation. Control and switching voltage 230V. Attention! The switching time between the up and down command must be ≥ 500ms (observe the technical data of the motor).
