For inductive loads like small relays or solenoid valves, derate per the switching curves: at 110 V it's rated 1 A, at 220 V it drops to 0.27 A. The 6 kV rated surge voltage means the contactor can withstand transient overvoltages common on industrial 24 VDC control buses without flashover. Shock resistance of 10g at 5 ms and 5g at 10 ms covers most vibration environments on a machine base or panel door — no special dampening needed for standard conveyor or pump skids. Depth is 114 mm, height 60 mm. Screw terminals accept 2x 0.25 to 2.5 mm² solid or stranded wire (2x 24 to 14 AWG). The holding power stays at 3.2 W DC, so the coil doesn't heat the enclosure noticeably even in a sealed panel.","metaTitle":"Siemens 3RH1335-2BB40-0AB3 SIRIUS Auxiliary Contactor, 24 VD","metaDescription":"Siemens SIRIUS 3RH1335-2BB40-0AB3 auxiliary contactor, 24 VDC coil, 10 A rated, size S00, 3 NO + 1 NC contacts, IP20 front, screw/snap-on mounting, current lifecycle.
