SIRIUS 3RF34 Solid-State Contactors

Siemens SIRIUS 3RF34 Solid-State Contactors are designed for switching motors and offer 3-phase operation for direct-on-line starting. These devices are ideal for frequently switching AC drives up to 7.5 kW and reversing up to 3kW. The 3RF34 solid-state contactors are equipped with a 2-phase control, ideal for typical motor current circuits that do not connect to the neutral conductor. These devices are fully insulated and can be mounted directly on SIRIUS motor starter protectors, overload relays, and current monitoring relays, enabling very simple integration into motor feeders. The 3RF34 contactors are available in two versions: SIRIUS 3RF34xBB 3-pole solid-state contactors and SIRIUS 3RF34xBD 3-pole solid-state reversing contactors. These SIRIUS 3RF34 solid-state contactors are ideal for load feeders.
