Product details

Key Ratings & Fit

The 3RT7036-1AH00: The contactor is size S2, 55 mm wide, 115 mm deep, 112 mm high. The front carries IP20 protection; the terminal area is IP00 — standard for panel-mount contactors where the enclosure provides the overall IP rating. Pollution degree 3, surge voltage resistance 6 kV. For a 3-pole contactor switching motor loads, the AC-3 rating to 690 V is the key spec — it governs the motor circuit it can handle. Coil holding power is 0.36 W DC; closing power is 0.79 W DC. Side-by-side mounting is permitted, which saves panel width on multi-contactor groups.

Frequently asked questions

Where can I buy 3RT7036-1AH00 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3RT7036-1AH00 drop into a panel specified around 3RT5035-1AH00?

Both are SIRIUS contactors with similar DIN-rail mounting (35 mm rail per DIN EN 50022), but the 3RT7036-1AH00 is a size S2 frame while the 3RT5035-1AH00 is a different frame size. Verify panel cutout and terminal spacing before substituting; the screw terminals and auxiliary contact options may differ.
