Coil is rated 220-240 V AC at 50/60 Hz with a pickup power factor of 0.8 (initial and holding), meaning the inrush current is higher than a DC-coil equivalent — factor this into the control transformer sizing if multiple contactors pick up simultaneously. Mechanical endurance is 10 million operations typical, but the electrical life depends heavily on the duty class: at AC-3 (standard motor switching) the contactor is rated for 1,000 switching cycles per hour, while AC-4 (plugging/inching) drops to 130 cycles per hour — the AC-4 ceiling is the real limiter for reversing or jogging applications. ## Termination and wiring — main poles and auxiliary Main power conductors terminate with stranded wire from 25 to 120 mm² — that covers everything from a 35 mm² feed to a 95 mm² motor cable, but the lug type (ring or fork) is not specified; expect to supply your own compression lugs for the larger sizes. Auxiliary and control wiring accepts solid or stranded conductors: 2x 0.5-1.5 mm² or 2x 0.75-2.5 mm² per terminal, max 2x 4 mm² — the screw terminals are shared between the coil and any add-on auxiliary switch block. The coil itself terminates via screw-type terminals, not quick-connects — this is standard for the S6 frame but means the control wiring must be stripped and torqued, not pushed on. ## Mounting clearances and orientation Mounting position allows vertical surface with +/-90° rotation and +/-22.5° tilt forward/back — so the contactor can be mounted on its side or at a slight angle, but not inverted (no upside-down mounting is listed). Minimum clearances to adjacent metalwork: 10 mm upwards, 10 mm downwards, 10 mm at the sides, and 20 mm forwards — the forward clearance is the tightest and matters most for arc-chamber venting; crowding the front face reduces the arc-quenching margin. ## Auxiliary contact ratings and switching performance The contactor includes an auxiliary switch (built-in or add-on — the listing confirms presence but not the contact configuration). Rated switching currents: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — these are the make/break capacities for the auxiliary contacts, not the main poles. Arcing time is 10-15 ms, and total operating time (both AC and DC coil) is 40-60 ms — the arcing time is short enough that a standard PLC scan cycle (10-20 ms) may miss a contact bounce event; use a 50 ms debounce on the feedback input if the auxiliary contact signals the main pole state. ## Environmental limits and storage Operating ambient temperature range is -25 to +60 °C, storage range is -55 to +80 °C — the -25 °C low end is fine for most indoor panels but marginal for unheated outdoor enclosures in northern climates; if the panel sees -30 °C, the contactor must be kept powered or heated.","metaTitle":"Siemens 3RT1054-6AP36-ZX95 SIRIUS Power Contactor, Size S6","metaDescription":"Siemens 3RT1054-6AP36-ZX95 SIRIUS power contactor, Size S6, 220-240 V AC coil, screw fixing, 170 mm depth.
