The 3RT7035-1AM00: The contactor mounts on 35 mm DIN rail per EN 50022 using screw or snap-on fastening. Side-by-side mounting is allowed, which keeps panel fill factor tight — 55 mm wide per unit. Main circuit and auxiliary/control wiring use screw-type terminals. The auxiliary contacts are rated for PLC-level signals — 17 V, 5 mA minimum switching capability — so you can wire them directly to a digital input card without a separate interface relay.
The contactor carries an insulation voltage rating of 690 V and surge voltage resistance of 6 kV, which aligns with IEC 60947-4-1 requirements for motor starting duty in industrial control panels.
Mounting position is flexible: ±180° rotation on a vertical surface, and tilt forward/backward by ±22.5°. This matters when you're fitting the contactor into a gland plate or a tight enclosure corner — you're not locked into one orientation. Operating temperature range is -10 to +55 °C; storage from -25 to +70 °C. Pollution degree 3 means it's suited for industrial environments with conductive dust or occasional condensation. For DC-13 loads at 220 V, the contactor switches 0.3 A — useful for DC brake coils or solenoid valves in the same panel. The magnet coil draws 0.78 W closing and 0.42 W holding at DC, so the control transformer sizing is modest.
