Product details

Rating & fit

The 3RT5056-8AP38-0PR0 is a Siemens SIRIUS power contactor rated 90 kW at 400 V AC-3 (50/60 Hz), which is the motor-switching duty class — it handles the inrush and breaking of squirrel-cage induction motors up to that power. The UC (universal current) coil accepts 220-240 V AC or DC, simplifying panel wiring where control voltage is mixed. Three main poles, size S6 frame with bar connections for high-current bus or cable terminations. Built-in auxiliary contacts: 2 NO + 2 NC, screw terminals. The conventional operating mechanical life is sized for frequent switching in pump, fan, and conveyor applications.

Compliance

RoHS compliance date listed as 04/24/2017, indicating the design meets EU substance restrictions from that date forward.
