That means you get four independent NO circuits in one 45 mm-wide package — no mixing NC and NO, just four make contacts for signal interlocking, PLC inputs, or pilot duty loads. The 6 kV rated surge voltage resistance means the contacts handle switching transients on inductive loads without welding shut prematurely. ## Mounting and panel fit for the S00 frame For AWG builds, that's 2x 20-16, 2x 18-14, or 2x 12. Finely stranded wire with core end processing uses the same cross-section ranges. ## Coil draw and operating limits AC coil with apparent pick-up power of 37 VA and holding power of 5.7 VA at 0.8 inductive power factor. The coil voltage tolerance is 0.8 to 1.1x rated at 50 Hz, 0.85 to 1.1x at 60 Hz — so a nominal 230 V coil stays pulled in down to about 184 V at 50 Hz.","metaTitle":"Siemens 3RH6140-1AR60 SIRIUS Contactor Relay, 4 NO, 6 A","metaDescription":"Siemens 3RH6140-1AR60 SIRIUS contactor relay, size S00, 4 NO auxiliary contacts rated 6 A at 24 V.
