Electronic Load Relay for Parameterizable Soft Startup

In addition to wear-free switching, the ELR W 3/9-400S electronic solid-state reversal relay with integrated soft starter now offers parameterizable soft startup for asynchronous machines up to approx. 4 kW. Measuring just 62 mm, the devices enable all the necessary operating parameters to be set individually for both a clockwise and counter-clockwise direction, including break off time, torque at start, start and stop time, torque at stop as well as braking period and breaking torque.

During operation, a display shows the percentage share of the switch state on the device.
