Product details

It carries three instantaneous normally-open (NO) contacts — no leading, lagging, or delayed switching. The coil is rated 24 V at both 50 Hz and 60 Hz, with a tolerance band of 0.8...1.1 at 50 Hz and 0.85...1.1 at 60 Hz.

The contactor mounts via screw and snap-on onto a DIN rail, occupying 45 mm width, 57.5 mm height, and 72 mm depth — the S00 footprint common across SIRIUS contactors and auxiliary contactors. Front protection is IP20, which means the terminals are finger-safe inside an enclosure but not sealed against moisture or dust — this is a panel-mounted component, not a field-mounted one. The screw terminals accept solid conductors: 2x 0.5...1.5 mm², 2x 0.75...2.5 mm², and 2x 4 mm², giving flexibility for daisy-chaining control wiring without additional terminal blocks.

The contacts are rated for switching at multiple voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 1 A at 690 V, plus intermediate ratings at 110 V (1 A), 220 V (0.27 A), and 500 V (2 A). These are the thermal current ratings for the contact set — they define the maximum continuous current the contacts can carry at each voltage. The typical mechanical life is 30 million operations, and the operating temperature range is -25 to +60 °C, with storage/transport range of -55 to +80 °C. Shock resistance is 10g for 5 ms and 5g for 10 ms, which covers vibration from contactors and drives in the same panel.

Frequently asked questions

Will 3RH1131-1AB00-0TK0 drop into a panel specified around 3RH2131-2AK60 without rewiring?

The S00 frame size and DIN-rail mounting are identical, so the physical fit is the same. However, the contact configuration differs: the 3RH1131-1AB00-0TK0 has 3 instantaneous NO contacts, while the 3RH2131-2AK60 may have a different contact arrangement (e.g., NC contacts or a mix). Check the contact count and coil voltage match the existing circuit. The screw terminal cross-sections are compatible, so rewiring is not required if the contact assignment is functionally equivalent.
