Product details

It is designed for control-circuit switching — signalling, interlocking, and logic-level isolation — inside a motor control centre or panel, not for direct motor load breaking.

The 3RH1131-2AF00-ZW95 is rated 10 A at 24 V, 6 A at 230 V, and 1 A at 690 V — these are the thermal continuous currents the contacts can carry in their respective AC voltage classes. For a 24 VDC control loop, 10 A gives generous headroom for pilot-duty solenoids and indicator banks. At 230 V, 6 A covers most contactor-coil and relay-coil switching in European panels. The 690 V / 1 A rating is for high-voltage auxiliary circuits in mining or marine gear. The contact reliability spec — one incorrect switching operation per 100 million at 17 V, 1 mA — means this contactor is trustworthy for PLC digital inputs and low-energy signal paths where oxide films on dry contacts cause nuisance failures. That is not a number every auxiliary contactor publishes, and it matters when you are interlocking safety circuits or position feedback.

Fastening is screw and snap-on mounting.

Shock resistance is 10g at 5 ms and 5g at 10 ms.

Frequently asked questions

What is the depth of 3RH1131-2AF00-ZW95?

The depth is 73 mm, measured from the mounting surface to the furthest projection. Combined with the 45 mm width and 60 mm height, it fits the standard S00 DIN-rail envelope.
