The Siemens SIRIUS 3RF2 series is a solid-state contactor two-phase controlled for switching resistive/inductive loads. It has operating temperature of 40 °C and blocking voltage of 1200 V. The type of electrical main current circuit and for auxiliary and control current circuit is through spring loaded 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
