The Siemens 3RT2015-2AP02-ZX95 is a SIRIUS S00 power contactor with a 24 VDC coil terminated via spring-type terminals. It mounts on a 35 mm DIN rail per DIN EN 60715 or directly with screws, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when fitting into a tight panel layout.
Duty cycles and what they mean for your load
The contactor is rated for 1 000 operations per hour at AC-1 (resistive loads), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). For AC-3e duty — the energy-efficient motor standard — it also carries 750/h. These numbers govern how fast you can cycle the contactor without overheating the coil or main contacts; if your application needs frequent jogging, the AC-4 limit of 250/h is the binding constraint.
Auxiliary contact ratings — pick the right voltage
The built-in auxiliary switch is rated 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 0.14 A at 440 V. These are the maximum continuous currents the auxiliary contacts can break at each voltage level — useful when driving a PLC input or a status lamp at a different potential than the main circuit.
Thermal limits and clearance
Operating ambient range is -25 to +60 °C; storage range extends to -55 to +80 °C. Minimum clearance to adjacent components: 10 mm upward, downward, and forward; 6 mm at the sides. These distances matter for heat dissipation and arc-flash containment — don't crowd the contactor against other heat sources or metal enclosures.
Sourcing and fit
The 3RT2015-2AP02-ZX95 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. For a panel originally specified with the 3RT2015-2AP01 (24 VDC coil, screw terminals), this ZX95 variant with spring-type terminals drops into the same footprint and DIN-rail slot — no rewiring of the main circuit needed, though the coil connection method differs.
