The 45 mm width and 72 mm depth match the standard S00 contactor footprint, so it snaps onto the same DIN rail alongside a 3RT2 contactor without stealing extra panel real estate. Fastens with both screw and snap-on mounting — no tools needed for the DIN rail clip, but the screw holes give you an option for vibration-heavy spots like a conveyor drive panel. Shock rated at 10g for 5 ms and 5g for 10 ms, which covers most industrial machine vibration profiles. ## Ratings that matter for the buyer The headline number is 10 A at 24 V — that's the current it can switch continuously through the 3 NO contacts at the coil voltage. But the real-world utility is in the voltage derating: at 110 V it's 1 A, at 230 V it's 6 A, at 400 V it's 3 A, and at 690 V it's 1 A. The 6 kV surge voltage resistance (rated impulse withstand) means it can live on the same panel as drives and contactors without arc-over on transient spikes. Contact reliability is spec'd at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the low-energy dry-circuit performance for direct PLC output driving. The 3 instantaneous contacts (make-before-break and delayed switching are both zero on this variant) give you a straight NO set with no timing tricks.","metaTitle":"Siemens 3RH1131-1HA80 SIRIUS Coupling Relay, 3 NO + 0 NC, 24","metaDescription":"Siemens 3RH1131-1HA80 SIRIUS coupling relay, size S00, 3 instantaneous contacts, 24 V DC coil, 10 A rated current.
