SIRIUS S00 power contactor — 3RT1015-1AP02-ZW98
Rated for 690 V at 4 kW, this contactor handles motor loads in AC-3 duty up to that power level. The coil operates at 50/60 Hz with a voltage tolerance of 0.8 to 1.1 times rated at 50 Hz and 0.85 to 1.1 at 60 Hz.
Panel integration and coordination
The S00 frame is the smallest Siemens contactor footprint, so it fits tightly on a DIN rail where space is at a premium. For short-circuit coordination, Type 1 requires a 35 A gL/gG fuse; Type 2 requires a 20 A gL/gG fuse. The difference matters for selectivity: Type 2 leaves the contactor usable after a fault, Type 1 may weld the contacts and require replacement. Wire the main circuit with the listed AWG range: 2x (20 to 16) solid or 2x (18 to 14) stranded, with a single 12 AWG maximum.
