Product details

SIRIUS S6 frame — panel fit and termination

The 3RT1456-6SP36-3PA0 is a Siemens SIRIUS contactor in the size S6 frame, measuring 120 mm wide by 172 mm high by 170 mm deep, with screw fixing for panel mounting.

Coil supply and auxiliary switching capacity

The magnet coil accepts 200-277 V AC/DC, covering common control voltages across 50/60 Hz systems without needing a separate coil variant.

Reliability and lifecycle — MTBF 75 a

Listed MTBF of 75 years means this contactor is a strong candidate for a critical spare holding — one in the cabinet before the line goes down.

Frequently asked questions

What is the MTBF of 3RT1456-6SP36-3PA0?
