Active production — no obsolescence headache
The 3RA2316-8XB37-1CL0: It's part of the Siemens SIRIUS family, size S00 — the smallest frame in the series, which keeps panel density high and spare-stock compact.
Motor power coverage — 400 V to 690 V, plus North American hp ratings
North American hp ratings span 2 hp at 200/208 V up to 7.5 hp at 575/600 V — useful for US and Canadian panel builds without derating guesswork. AC-4 rating is also 4 kW at 400 V, meaning it handles plugging and inching duty at the same power level as AC-3 — no derating for reversing applications.
Mounting flexibility that saves panel time
Snap-on mounting onto 35 mm standard DIN rail, plus screw fixing — you can choose whichever gets the job done faster on the rail. Dimensions 130 mm deep × 90 mm wide × 68 mm high — the depth is the number that matters for shallow cabinets; it fits behind most standard enclosure doors.
Wiring terminals — screw-type, field-friendly
The coil terminals are also screw-type, so you're not hunting for a different tool when wiring the control circuit.
Environmental range and compliance
Operating temperature -25 to +60 °C covers unheated plant floors; storage range -55 to +80 °C means it can sit in a warehouse through seasonal extremes. RoHS compliance date 07/01/2006 — the declaration is on file for EU substance restriction documentation.
