Mounting and Clearance Checklist
The 3RT2035-1KB44-3MA0: Snaps onto 35 mm DIN rail (DIN EN 60715) or screws directly to the panel. Minimum air gap to other metal: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm to the side. The contactor can be rotated ±180° on a vertical mounting surface and tilted forward/backward ±22.5° — so awkward cabinet positions can be worked around without custom brackets. Plan for the 174 mm depth if your gland plate is tight.
Sourcing and Lifecycle
The lifecycle status is current — meaning Siemens is actively producing this code and there is no planned discontinuation. That gives you BOM stability for new designs and spare parts. We can provide an RFQ for your quantity; lead time varies but the supply channel is healthy. No drop-in replacement needed.
