Side-by-side mounting is permitted with 6 mm spacing to adjacent devices for heat dissipation. The spring-loaded terminals on the main current circuit accept 2x (0.25... 2.5 mm²) solid or stranded conductors (2x 24...14 AWG), so no ferrule crimping is required for stranded wire — a time-saver during panel build. ## Rated operational currents and coordination Rated for AC-12 resistive loads at 10 A maximum, and AC-2 motor duty at 3 kW / 400 V. For short-circuit protection, type 2 coordination requires a gL/gG fuse rated 20 A; type 1 coordination allows up to 35 A. The auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V DC, covering both PLC-level signal switching and higher-voltage interlock circuits.","metaTitle":"Siemens 3RT1015-2BB42-ZX95 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1015-2BB42-ZX95 power contactor, size S00, 24 VDC coil, spring-loaded terminals, screw and snap-on DIN rail mount.
