Product details

SIRIUS S3 contactor with universal AC/DC coil

The 3RT2348-1NP30: It accepts a universal AC/DC coil supply spanning 175 to 280 V, simplifying panel design where mixed control voltages are present. Arcing time falls between 10 and 20 ms, a parameter for coordination studies with upstream short-circuit protection.

Dimensions are 140 mm height, 96 mm width, and 152 mm depth. Main power conductors accept stranded wire from 6 to 70 mm². The coil connection uses screw-type terminals.

Auxiliary contact ratings and operating envelope

An auxiliary switch is integrated. Up to two auxiliary switch blocks can be attached. The coil operates reliably between 0.8 and 1.1 times the rated voltage. Operating times (closing and opening) are 38 to 57 ms for both AC and DC supplies.

Sourced through independent distribution channels. Let me be transparent: same part, different passport — genuine Siemens stock is quoted to order.
