Front protection is IP20; the terminal area is IP00. Rated for motor loads: at AC-2 duty at 400 V it handles 7.5 kW; at AC-4 at 400 V the operating current is 15.5 A. For high-voltage motors, it supports 10 kW at 500 V and 11 kW at 690 V. DC switching ratings are voltage-dependent: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V. Pollution degree 3. The contactor is rated for 10 000 000 typical mechanical operations. Solid and stranded wire capacities for the main circuit: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). For single or multi-stranded conductors: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents: 2x (16 to 12), 2x (14 to 10), 1x 8. Type 2 coordination requires a 25 A gL/gG fuse. The contactor includes 2 auxiliary contacts (instantaneous).","metaTitle":"Siemens 3RT1025-1AP08-0MA0 SIRIUS Power Contactor, S0 Frame,","metaDescription":"Siemens SIRIUS power contactor 3RT1025-1AP08-0MA0, S0 frame, 3 NO main contacts, 45 mm wide, screw terminals, 35 mm DIN rail mount.
