The coil draws 12.5 VA at 50 Hz and has a power factor of 0.36 at 60 Hz, so the control transformer must be sized for that inrush. The auxiliary contact ratings are given at several voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V, 1 A at 440 V — these are the make/break capacities for the control circuit, not the main poles. The mechanical life is typical 10 000 000 operations. For short-circuit protection, a gL/gG fuse rated 80 A is required with type of assignment 2. Main circuit terminals accept solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²), and stranded 2x (0.75 to 25 mm²). AWG range for main contacts is 2x (18 to 2). The coil uses screw-type terminals. Mounting position allows vertical surface with +/-180° rotation and +/-30° tilt front/back. Dimensions: 112 mm height, 73 mm width, 115 mm depth.","metaTitle":"Siemens 3RT1535-1AH00 SIRIUS Power Contactor, Size S2, Screw","metaDescription":"Siemens 3RT1535-1AH00 SIRIUS power contactor, size S2, screw terminals for main and aux circuits. 40 A per contact, 6 kV impulse.
