Motor isolation relay, 2+2 normally open contacts, not potential-free, 4A/250V AC, for two 230V motors. No standby loss. For flush mounting. 49x51mm, 20mm deep. The connection terminals are plug-in terminals for conductor cross-sections from 0.2mm² to 2.5mm². The MTR is a control relay for controlling one or two blind and roller shutter motors with mechanical or electronic limit switches. The tubular motors of shading elements and roller shutters must never be connected directly in parallel, as this would otherwise lead to reverse voltages via the limit switches and ultimately to the destruction of the motors. Several MTRs can be connected in parallel at the inputs. EGS12Z, EGS61Z, FSB14, FSB61NP and FJ62NP are suitable for control. Control and switching voltage 230V. Attention! The switching time between the up and down command must be = 500ms, otherwise the motor or the isolating relay may be damaged (note the technical data of the motor).
