What This Part Is and Where It Fits
The Siemens 3RT1036-1AN24-ZX95 is a SIRIUS power contactor in the S2 frame size, designed for switching motor loads in industrial control panels. It mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 50022, so it integrates into a standard panel layout without special brackets. The contactor is rated for 30 kW at 500 V and 11.4 kW at 690 V in AC-3 duty, which covers most three-phase induction motor applications in that power band. For AC-2 duty (slip-ring motors or reversing starts), it carries 22 kW at 400 V. The coil is wound for 220 V at both 50 Hz and 60 Hz, with an operating range of 0.8...1.1 times rated voltage at 50 Hz and 0.85...1.1 at 60 Hz. That means the coil holds in reliably even if the line voltage sags to about 176 V on a 50 Hz supply.
Key Ratings and What They Mean for Your Panel
The contactor body measures 55 mm wide by 112 mm high by 164 mm deep. At 55 mm, it occupies a standard three-module width on the DIN rail, so you can plan your enclosure fill factor accordingly. Side-by-side mounting is permitted, which means no mandatory spacing between contactors on the rail. The main power circuit uses screw-type terminals, accepting solid conductors from 2x 0.5...1.5 mm² up to max 2x 0.75...4 mm², and stranded conductors from 2x 0.75...25 mm². That range covers standard motor cables up to about 6 AWG stranded, so no lugging or adapter needed for most installations. Auxiliary contact ratings are given at multiple voltages: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. These are the make/break capacities for the control circuit, so verify your PLC output or relay load stays within these limits per the voltage you're switching. The front face carries IP20 protection (finger-safe), while the terminals themselves are IP00. That's standard for panel-mounted contactors — the enclosure provides the overall IP rating, and the contactor's own terminal protection is minimal because it's inside a cabinet. Rated for pollution degree 3, this contactor is suited for industrial environments where conductive pollution or dry non-conductive pollution that becomes conductive due to condensation is expected. That covers most factory-floor panels without special derating. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. The mechanical service life is rated at 10 million operations typical, though electrical life depends on the switching category and load current.
Sourcing and Lifecycle Reality
Because it's an active SIRIUS catalog item, you can quote it to order against an RFQ. No last-time-buy urgency or broker-channel scavenging needed for this order code.
