Siemens 3RT5036-1AB00 SIRIUS Power Contactor — S2 Frame, 55 mm, 690 V
The contactor carries a 690 V rated insulation voltage and delivers 22 kW at 230 V, 38 kW at 400 V, and 66 kW at 690 V, all at 60 °C ambient, so it handles motor loads in the 22–66 kW range depending on line voltage. The main current circuit uses screw-type terminals accepting 2x (0.75–16 mm²) solid or stranded, or 2x (18–2 AWG). Auxiliary and control circuits also use screw terminals, and the product extension for auxiliary switches is available — add a block later without changing the contactor.
Side-by-side mounting is permitted — no derating for adjacent units in the spec.
Rated switching frequency at AC is 5 000 operations per hour; AC-1 maximum is 1 000 1/h, AC-3 maximum is 800 1/h, AC-4 maximum is 300 1/h, and AC-3e maximum is 800 1/h. Coil draws 6 A at 24 V rated value, 6 A at 230 V rated value, 1 A at 110 V, 0.3 A at 220 V, and 3 A at 400 V. The coil operates at 50 Hz, 24 V rated value. Mechanical service life of the contactor typical is 10 000 000 operations. The contactor is rated for AC-3e maximum voltage of 690 V.
