Product details

The Siemens 3RT1015-2KB41 is a SIRIUS Size S00 power contactor with a 24 VDC coil, rated for 10 A at 24 V on the main contacts.

Motor duty and coordination

In AC-2 duty at 400 V, this contactor switches 3 kW motor loads — typical for slip-ring motors or moderate switching frequency. 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).
