Panel Fit and Mounting
The 3RT2015-1AK61-ZX95: This SIRIUS contactor is Size S00, the smallest frame in the Siemens contactor family, with a 45 mm width that fits standard 35 mm DIN rail per DIN EN 60715 using either screw fixing or snap-on mounting. The 73 mm depth and 58 mm height leave room for wiring ducts and adjacent devices; clearance requirements are 10 mm upward, 10 mm downward, 10 mm forward, and 6 mm at the side. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, so it adapts to tight enclosures without derating.
Wiring and Terminal Specs
Main contact terminals accept solid or stranded wire from 0.5 to 4 mm², and up to 2x 4 mm² or 2x (0.75 to 2.5 mm²) for paralleled feeds. The magnet coil uses screw-type terminals, so no special crimp tooling is needed for the control circuit.
Switching Duty and Lifecycle
Rated for 750 switching cycles per hour in AC-3 and AC-3e duty, and 250 cycles per hour in AC-4 — the AC-4 figure matters for reversing or plugging applications where the contactor breaks full-load current. Mechanical life is 30 million operations typical, so this contactor outlasts most panel designs before a swap is needed. Operate time is 7 to 13 ms AC, arcing time 10 to 15 ms — fast enough for most motor-start sequences but not for high-speed DC switching.
Auxiliary Contact Ratings
Built-in auxiliary switch rated 10 A at 24 V, 3 A at 400 V, and 0.3 A at 220 V — these are the continuous current limits for the signal circuit, not the main power path. At 230 V the auxiliary is rated 0.75 hp, so it can drive a small pilot motor or contactor coil directly.
Environmental and Compliance
Operating temperature range -25 to +60 °C; storage range -55 to +80 °C, covering most industrial enclosures and unheated warehouses.
