SIRIUS 3RF2 Solid-State Relays & Contactors

Siemens SIRIUS 3RF2 Solid-State Relays (SSRs) are suitable for surface mounting on existing cooling surfaces. 3RF2 SSRs, which do not include a heat sink, provide quick and easy mounting with two screws. The capacity reaches up to 88A on resistive loads, depending on the heat sink. The SSRs come in single-phase relays with a width of 22.5mm or 45mm or a three-phase relay with a width of 45mm. Siemens SIRIUS 3RF2 Solid-State Contactors feature an integrated heat sink and are available in a single-phase version with currents up to 70A or a three-phase version with currents up to 50A.
