Product details

S00 auxiliary contactor, 4 NO contacts, 24 V coil

The 3RH2140-2AB00-ZX95 is a SIRIUS auxiliary contactor in size S00, carrying four instantaneous normally-open contacts. These are the contact ratings the buyer needs to match against the load in the control circuit.

Panel fit and mounting positions

This means it fits into tight enclosures where the rail orientation isn't ideal. These are the minimum air gaps to adjacent metalwork or other devices — plan the panel layout around these numbers to avoid derating or flashover. The S00 footprint is shared across the SIRIUS contactor family, so swapping between a 3RT2 contactor and this auxiliary block keeps the same DIN-rail real estate.

Switching performance and environmental limits

Maximum switching frequency at DC is 10,000 operations per hour — useful for rapid cycling applications like valve positioners or indexing tables. This is a wear-out figure, not a guarantee — but for a contactor switching a PLC output or relay coil a few times per cycle, it's effectively a lifetime component in most panel applications.

Lifecycle status is current production — this is an active catalog item, not a legacy or NRND part.
