Its headline rating is 12.5 kVAr at 400 V — that is the maximum capacitive load it can make and break without welding contacts or causing transient overvoltages on the line. A standard power contactor of the same frame size would have a lower capacitive switching life; this part is designed for the high inrush current and repetitive daily switching that capacitor banks demand. Three NO main contacts carry the capacitor current; the built-in auxiliary block gives one NO and one NC contact for status feedback to the controller or for interlocking with the main breaker. The S00 frame takes a 45 mm wide footprint on the rail. Side-by-side mounting is permitted, so multiple capacitor steps can pack tightly in a PFC panel. ## Lifecycle and replacement path ## Termination and wiring note Screw-type terminals on both the main current circuit and the auxiliary/control circuit. The S00 frame accepts the standard conductor sizes for a 20 A rated contactor — 2.5 mm² solid or stranded for the power path, 1.5 mm² for the control wiring. Strip length of 8–10 mm, torque to the manufacturer's specification on the nameplate.","metaTitle":"Siemens 3RT1617-1AB03 Capacitor Contactor, 12.5 kVAr, 24 V A","metaDescription":"Siemens SIRIUS 3RT1617-1AB03 capacitor contactor, AC-6 rated 12.5 kVAr at 400 V, 24 V AC coil, 3-pole, Size S00.

The 3RT1617-1AB03 is an AC-coil capacitor contactor with a 24 V AC coil and a different auxiliary contact configuration. The terminal layout and coil voltage differ, so a panel rewire is required.
