For Type 2 coordination, the upstream fuse is 25 A gL/gG; Type 1 allows up to 63 A gL/gG. S0 frame means 45 mm width, 85 mm height, 90 mm depth — a standard footprint for 7.5 kW contactors. Screw terminals accept 2x (0.25…2.5 mm²) solid or 2x (1…2.5 mm²) stranded, up to 2x 10 mm² or 1x 8 AWG. Side-by-side mounting is permitted, with 6 mm spacing at the side. Coil operates at 50 Hz (0.8…1.1 x rated voltage) or 60 Hz (0.85…1.1 x rated voltage). The 400 V rated value at 50 Hz and 400…440 V at 60 Hz define the main pole voltage, not the coil — verify the coil code suffix for your control voltage. The contactor carries 10 A at AC-12 (control-circuit load) and provides auxiliary contacts rated for 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. No instantaneous contact (zero auxiliary contact blocks included as standard).","metaTitle":"Siemens 3RT1025-3AR60 SIRIUS Power Contactor, 7.5 kW AC-2, S","metaDescription":"Siemens 3RT1025-3AR60 SIRIUS power contactor, S0 frame, 7.5 kW at AC-2 400 V, 15.5 A AC-4.
