Auxiliary contacts are rated for PLC-level reliability at 17 V, 5 mA — meaning the same contactor can switch both power and low-level control signals without a separate interface relay. Surge voltage resistance is 6 kV, supporting coordination with upstream surge protection devices. ## Coordination and protection planning For type 1 coordination (contactor may need replacement after fault), the fuse rating is 80 A. These values let the panel designer size the branch circuit protection without over-fusing. The magnet coil draws 0.82 W during closing and 0.24 W holding at DC — the low holding power reduces heat buildup in dense panels.","metaTitle":"Siemens 3RT7026-1AV00 Contactor, S0, 3-Pole, 6 A at 230 V","metaDescription":"Siemens 3RT7026-1AV00 SIRIUS contactor, size S0, 3 NO main contacts, 6 A at 230 V AC-3.
