It carries a 24 VDC coil and four main poles, terminated with spring-loaded terminals for tool-less wiring. The S00 frame keeps the footprint compact at 45 mm wide, 60 mm tall, and 72 mm deep, so it fits tightly on a DIN rail alongside other SIRIUS components without crowding the enclosure.
The coil pick-up voltage range is 0.85 to 1.1 times the rated value (24 VDC), so the contactor pulls in reliably at 20.4 VDC and holds in up to 26.4 VDC. Front face is IP20, so finger-safe when installed in a closed panel. The terminal area is also IP20, meaning the spring-loaded connections are touch-safe without additional shrouding.
Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire. Strip length is not stated here, but the spring-cage design typically needs 8–10 mm — verify against the terminal marking on delivery. The maximum wire size at AC-1 rating is 2.5 mm², so plan for that as the practical limit for power wiring. Above that, the dielectric strength drops and the contactor may need to be de-rated for voltage and current — not typical for most industrial sites but relevant for high-altitude installations.
The 3RT1517-2BB48-0KT6 is the spring-loaded terminal variant of the S00 4-pole contactor. If your BOM specifies a screw-terminal version, the standard 3RT1517-1BB48 (screw terminals) is the direct functional equivalent — same coil, same ratings, same footprint, just different termination. That swap keeps the panel layout identical.
