Product details

Motor Switching Ratings — What the Duty Classes Mean

Rated 15 kW at AC-2 duty at 400 V, this contactor handles slip-ring motor starting where the load current stays below make/break stress. For AC-4 duty (plugging, inching, reversing) at 400 V, it carries 29 A — the more severe switching class that governs contact life under frequent reversals. The AC-3 maximum operating rate of 1,000 cycles per hour suits conveyor and pump cycling, while AC-4 maxes at 250 cycles per hour due to the heavier arc stress.

Substance prohibitance dated 05/01/2012 aligns with RoHS and REACH compliance timelines. The SIRIUS series carries IEC and UL certifications for global panel acceptance, though specific agency marks are not listed in this record.

Frequently asked questions

What are the key motor ratings for this contactor?

It is rated 15 kW at AC-2 duty at 400 V for slip-ring motor starting, and 29 A at AC-4 duty at 400 V for severe switching applications like plugging and reversing.

What is the mounting method and footprint?

It mounts via screw and snap-on onto 35 mm standard DIN rail per DIN EN 50022. The width is 55 mm, depth 115 mm, and height 112 mm, allowing tight side-by-side mounting without derating.

What conductor sizes does the screw terminal accept?

Solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²). Stranded: 2x (0.75...25 mm²).

How does this compare to the 3RT1036-1AB00?

The 3RT1036-1AB00 is a larger frame (Size S3) with higher current ratings. The 3RT1034-1AL00-ZX95 (Size S2) is a smaller, lower-rated contactor. They share the same SIRIUS platform and DIN rail mounting, but the 3RT1036 will not drop into a panel wired for the S2 footprint without rewiring the main power lugs and checking panel fill factor.
