Product details

For AC-4 duty (plugging, inching, reversing under full load), it carries 41 A at 400 V. At 500 V it handles 30 kW, and at 690 V it handles 11.4 kW — useful for higher-voltage motor circuits in European or export panels.

RoHS compliance date is 05/01/2012, so it meets the EU substance restrictions for new installations.

Solid wire: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max. 2x (0.75...4 mm²). Stranded: 2x (0.75...25 mm²). Minimum permissible cross-section at 40 °C is 16 mm² for the main circuit. IP20 on the front (finger-safe), IP00 at the terminals — so the connection area must be inside an enclosure or guarded.

Mechanical and electrical endurance

Electrical life depends on duty: AC-1 maximum 1,000 cycles/hour, AC-2 maximum 400 cycles/hour, AC-3 maximum 800 cycles/hour, AC-4 maximum 300 cycles/hour.

Frequently asked questions

What is the closest functional second-source to 3RT1036-1AD04?

The 3RT1044-1FB46 is a larger-frame SIRIUS contactor (size S3 vs S2) with different ratings — it will not drop into the same panel without rewiring and space changes. For a direct functional match within the same S2 footprint, the 3RT5036-1AB00 or 3RT5036-1AP00 are closer siblings, but verify coil voltage and terminal layout against your BOM.
