The auxiliary circuit also withstands 6 kV. For short-circuit protection, the manufacturer specifies a gL/gG fuse rated at 80 A with type of assignment 2. Auxiliary contact ratings vary by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and lower values at higher DC voltages — 2 A at 60 V DC, 1 A at 110 V DC, 0.3 A at 220 V DC. The contactor measures 112 mm high, 73 mm wide, and 130 mm deep. Wire termination for the main circuit accepts 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 accept 2x (0.75 to 25 mm²). AWG equivalents for main contacts are 2x (18 to 2). The part is RoHS compliant with a substance prohibition date of 01.05.2012.","metaTitle":"Siemens 3RT1535-1BE40 SIRIUS Power Contactor, S2, 80 A Fuse","metaDescription":"Siemens SIRIUS 3RT1535-1BE40 power contactor, size S2, 80 A gL/gG fuse protection, screw terminals, 35 mm DIN rail.
