The Siemens 3RT2018-1AP61 is a SIRIUS S00 power contactor, 45 mm wide, with screw-type coil and main terminals. Mechanical life is rated 30 million operations typical — the contactor will outlast most panel refurbishments in cycling applications like conveyors or pumps. Switching frequency reaches 750 operations per hour under AC-3 duty, so it handles moderate-speed motor starting without derating.
Mounting & Wiring
Mounting is screw and snap-on onto 35 mm DIN rail per DIN EN 60715. The contactor can be rotated ±180° on a vertical surface and tilted forward or backward up to 22.5°, giving panel builders layout flexibility. Wire range accepts solid or stranded 0.5–4 mm², with multiple 2-conductor combinations allowed. Screw terminals on both coil and main contacts mean standard termination tools, no special push-in lever needed. Depth is 73 mm, width 45 mm — the smallest S00 footprint for tight enclosures.
Lifecycle & Sourcing
Production status is active — this part is in current manufacturing. No last-time-buy or phase-out risk. Standard lead times apply; source to order against an RFQ. If you are locking down a BOM line, this contactor is a straightforward, stable choice.
