What It Is and Where It Fits
The 3RT2015-1FB41-ZW96: It snaps onto a 35 mm DIN rail per DIN EN 60715, with screw and snap-on fastening, so it integrates into any standard panel layout without special brackets. The mounting position is flexible — you can rotate it ±180° on a vertical surface or tilt it ±22.5° forward and backward, which helps when you're squeezing it into a tight enclosure.
Key Ratings and What They Mean for Your Line
The coil is rated at 24 VDC nominal, with a pickup threshold of 0.8 times rated and a dropout at 1.1 times rated — meaning it pulls in reliably at about 19.2 V and drops out above 26.4 V. That's a standard control voltage for most PLC-driven panels, so you won't need a separate power supply for the coil. For the main contacts, the contactor is rated for AC-3 duty (motor switching) at a maximum of 750 switching cycles per hour, and AC-1 (resistive) at 1000 cycles per hour. If you're running a motor start/stop application, that 750 ops/h is the number to watch — it's the duty cycle that governs contact life under inductive loads. The mechanical life is typical at 30 million operations, so the contacts will wear out long before the mechanism does. The auxiliary switch is present and rated for various control voltages: 10 A at 24 V, 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. That covers most signal-level switching you'd need for status feedback or interlocking — just match the voltage to your control circuit. It handles wire sizes from 0.5 to 4 mm² solid or stranded, and can accept two conductors per terminal for daisy-chaining. The coil terminals are screw-type, so you'll need a screwdriver for termination — no spring-cage here, but that's typical for this size class and gives a solid connection in high-vibration environments.
Thermal and Environmental Limits
Operating temperature range is -25 to +60 °C, and storage range is -55 to +80 °C. That means it'll survive a hot panel in summer and a cold warehouse in winter, but if your enclosure sits in direct sun or near a furnace, you'll want to check the ambient at the contactor location — the operating limit is the one that matters for continuous duty.
Physical Fit and Clearances
Dimensions are 58 mm high, 45 mm wide, and 73 mm deep — a compact footprint that fits in a standard 45 mm wide DIN-rail slot. For clearance around the contactor, allow 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the sides. That's tight enough to pack multiple units side by side, but don't skimp on the side clearance if you're running high-current loads — arcing time is 10 to 15 ms, and you want that arc to extinguish without bridging to adjacent metal.
