Product details

Rated for 22 kW at 500 V and 18.5 kW at AC-2 duty at 400 V, it handles the heavy inductive switching of wound-rotor or slip-ring motors. The AC-4 rating of 35 A at 400 V covers reversing and inching applications where contact wear is higher.

Termination and wiring

Main current circuit uses screw-type terminals. Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded conductors: 2x (0.75 to 25 mm²). At 40 °C, minimum permissible cross-section is 16 mm². Front face is IP20; terminals are IP00, so the contactor needs enclosure protection in washdown or dusty environments. Side-by-side mounting is permitted, which saves rail space in multi-contactor groups.

Mechanical life is typical 10,000,000 operations. Maximum switching frequency varies by duty: AC-1 at 1,200 cycles/hour, AC-2 at 600, AC-3 at 1,000, AC-4 at 300.

Frequently asked questions

What is the closest functional second-source to 3RT1035-1AB04?

The 3RT1036-1AB00 is a size S2 contactor in the same SIRIUS family, but it is a higher-rated variant. The 3RT1035-1AB04 will not drop into a panel wired for the 3RT1036-1AB00 without checking the terminal assignments and power ratings, as the coil and auxiliary configurations may differ.

What is the depth of 3RT1035-1AB04?

The depth is 164 mm, width is 55 mm, and height is 112 mm.

What solid conductor sizes does the 3RT1035-1AB04 accept?

It accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²) solid conductors. Stranded conductors up to 2x (0.75 to 25 mm²) are also accepted.

What compliance documentation does Siemens provide for 3RT1035-1AB04?

The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance. Standard Siemens documentation includes a CE declaration and, for this series, typically UL and CSA certifications are available upon request.
