These are the numbers that govern real motor switching — not a generic thermal current. For short-circuit protection, the contactor coordinates with a 35 A gL/gG fuse under Type 2 coordination (limited damage to the contactor) or a 100 A gL/gG fuse under Type 1 coordination (contactor may need replacement after a fault). The auxiliary contact block (not included) can be mounted on the front or side; side-by-side mounting is permitted with 6 mm spacing to adjacent devices.","metaTitle":"Siemens 3RT1026-3AU60 SIRIUS Power Contactor, S0, 3NO, 11 kW","metaDescription":"Siemens SIRIUS 3RT1026-3AU60 power contactor, size S0, 3-pole NO main contacts.
