Siemens Halvlederrelæ, 1-polet ST, DIN-skinne-montering, Maks. 230 V, 20 A Thyristor, Short-circuit resistant with

The Siemens SIRIUS 3RF2 series is a solid-state contactor single phase for switching resistive/inductive loads. It has operating temperature of 40 °C. The type of electrical main current circuit and for auxiliary and control current circuit is through screw type terminal. It is non-wearing and silent and are ideal for noise-sensitive areas. It is also extremely reliable at high switching frequencies. As the heat sink is already integrated, they can be used directly in the control cabinet. The compact design saves space on the mounting rail.

Operating frequency is 50 to 60 Hz
Protection class IP is IP20
