The Siemens 3RT5036-1BB40 is a SIRIUS-brand power contactor in size S2, rated for switching motor loads up to 38 kW at 400 V AC-3e and 66 kW at 690 V AC-3e. Main and auxiliary circuits use screw-type terminals, with the main circuit accepting 2x (0.75 to 16 mm²) solid or stranded wire.
Pollution degree 3 suits industrial control panels without climate control.
The coil is rated 24 VDC and draws 6 A at rated value. It also has lower current draws at higher control voltages: 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V.
Width is 55 mm, height is 112 mm, and depth is 130 mm.
