Part identity and key ratings
The Siemens 3RT1015-2AP01-ZW97 is a SIRIUS power contactor in the compact S00 frame size, designed for switching motor loads in control panels. It mounts via screw or snap-on onto a 35 mm DIN rail per EN 50022, and the main circuit uses spring-loaded terminals for tool-less wiring. For motor duty, the AC-3 rating at 400 V is 7 A, supporting a 3 kW motor at 400 V AC-2. At 690 V, the contactor handles 4 kW. The AC-4 reversing/inching rating is 6.5 A at 400 V — a useful figure for applications requiring frequent jogging or plugging. The coil operates over a 0.8...1.1 x Us range at 50 Hz and 0.85...1.1 x Us at 60 Hz, with a rated operational voltage of 230 V at both frequencies. This wide pick-up tolerance helps maintain hold-in during brownout conditions common on industrial lines.
Mounting and wiring constraints
The contactor occupies 45 mm width, 60 mm height, and 73 mm depth — the S00 footprint that fits standard 45 mm DIN-rail spacing. Side-by-side mounting is permitted with no derating, so multiple units pack tightly on the rail. Spring-loaded terminals accept 2x (0.25...2.5 mm²) solid or stranded conductors, or 2x (24...14 AWG). The front face carries IP20 finger protection; the terminals themselves are also IP20. Pollution degree 3 (conductive pollution) is specified, meaning the contactor is rated for the typical industrial panel environment without conformal coating. For type 2 coordination (no weld), a gL/gG fuse of 20 A is required; for type 1 coordination (welding allowed but no fire risk), a 35 A fuse suffices. These values guide the upstream protection selection — critical for SCCR compliance in UL 508A panels.
Lifecycle and sourcing posture
The -ZW97 suffix indicates a special version (likely a customer-specific variant or special packaging). Verify the exact variant code against your original purchase order or nameplate to ensure the -ZW97 marking matches your requirement — a standard 3RT1015-2AP01 may not carry the same approvals or markings.
Environmental and service life
Operating temperature range is -25 to +60 °C, with a maximum altitude of 2,000 m without derating. The mechanical service life is 30 million operating cycles — typical for the S00 frame and sufficient for most conveyor, pump, and fan applications where switching frequency is moderate. Auxiliary contact ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — these are for the built-in instantaneous auxiliary contact (1 N.O. or 1 N.C., depending on variant). The AC-12 maximum operating current is 10 A, covering resistive loads on the aux circuit.
