SIRIUS S2 contactor — 175…280 V AC/DC coil, built for the panel
The Siemens SIRIUS 3RT2336-1NP30-0JB0 is an S2-frame contactor with a universal AC/DC magnet coil rated 175…280 V.
Coil and switching specs
Coil inrush peaks at 5 A, steady-state draw is 2 VA at both 50 and 60 Hz. Pickup and dropout times are 30…55 ms AC and DC, arcing time runs 10…20 ms. The auxiliary switch is included, rated for 24 V at 10 A, 230 V at 10 A, and 400 V at 3 A — enough for direct pilot-duty control of small motors or contactor feedback.
The S2 frame measures 75 mm wide, 114 mm tall, and 130 mm deep.
Terminal capacity
Screw-type terminals accept solid or stranded wire: 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²). That covers standard control wiring up to 14 AWG — no ferrule crimping needed for solid runs, but stranded benefits from bootlace ferrules for clean insertion.
