The front and terminal faces carry IP20 protection — suitable for enclosed panel use where touch protection is required but no washdown exposure. ## Ratings and Coordination The main contacts are 3 NO (normally open). Pollution degree 3 applies. For the auxiliary contact circuit, at 230 V rated value is 6 A, at 400 V rated value is 3 A, and at 690 V rated value is 1 A (50/60 Hz). Fuse coordination: for type 2 coordination, use gL/gG NH 3NA 35 A; for type 1 coordination, use 80 A. Maximum switching frequency at AC-3 is 800 operations per hour; at AC-4 it is 250 operations per hour. Shock resistance: 12.5g for 5 ms, 7.8g for 10 ms (sine pulse). ## Dimensions and Wiring Dimensions: width 45 mm, height 85.5 mm, depth 91 mm. Wire capacity: solid or stranded 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²); finely stranded with ferrule also 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²).","metaTitle":"Siemens 3RT7026-1AN20 Contactor, S0, 3-Pole, 690V AC-3, 24V","metaDescription":"Siemens 3RT7026-1AN20 SIRIUS contactor, size S0, 3-pole, 690V AC-3 max, 24V DC coil, IP20.
