Product details

Active SIRIUS direct starter — 2 A AC-3, Class 10, IP55

The 3RK4353-3FR58-0BA0: Rated operating voltage is 340...440 V AC; the control supply accepts 184...253 V at 50 Hz or 196...253 V at 60 Hz.

Panel fit and mounting flexibility

Ambient operating range is -25 to +35 °C; the 50 % low-demand rate per SN 31920 means the thermal capacity is sized for intermittent duty cycles, not continuous full-load.

Short-circuit protection and wiring note

One digital input is available for local control or feedback; the main current circuit is 3-pole, and there is no bus communication (no PROFINET, PROFIBUS, or AS-Interface on board). No brake control output is fitted — this variant is for plain motor starting without a DC or AC brake coil.
