Solid-State Relays 3-Phase 45 mm

SIRIUS 3RF22 Solid-State Relays 3-Phase 45 mm

The 3-phase zero-point switching solid-state relays have a compact 45 mm width – saving space and offering a competitively priced solution to switch 3-phase loads.

Depending on the heat sink used, loads of up to 55 A can be switched.

Furthermore, you can select between 2- and 3-phase controlled versions. The 2-phase controlled version distinguishes itself as a result of having the lowest power loss; the 3-phase version can be used when all three phases must be switched in operation.

Essentially the same as our 3RF21 solid- state relays, the power is connected at the top and the load at the bottom. The control circuit can be pre-wired thanks to the removable control connector.
