For AC-4 duty (plugging, inching, reversing) at 400 V, it's rated 6.5 A. Type 2 coordination requires a 20 A gL/gG fuse; type 1 coordination allows a 35 A gL/gG fuse. The built-in varistor surge suppressor handles coil suppression without an external diode. ## Integration notes The 45 mm wide, 60 mm tall, 73 mm deep footprint fits standard S00 panel layouts. Side-by-side mounting is allowed with a 6 mm gap to adjacent devices. The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire (2x 24 to 14 AWG).","metaTitle":"Siemens 3RT1015-2KB41 SIRIUS Power Contactor, 24 VDC, Size S","metaDescription":"Siemens 3RT1015-2KB41 SIRIUS power contactor, Size S00, 24 VDC coil, 10 A at 24 V, spring-loaded terminals, IP20.
