Modular design for mounting on 35 mm DIN rail. The AC output circuit with antiparallel thyristors allows for a high number of switching cycles without wear on the contact material. It offers silent switching and a low control current.

The zero-cross switching version reduces inrush current by switching at the zero point, making it particularly suitable for lamp loads, especially energy-saving lamps, as well as for switching lamp groups, inductive loads, and capacitors.

The instant switching version enables wear-free switching at high frequencies and higher loads, making it particularly suitable for resistive and inductive loads.
