The contactor can be mounted on a vertical surface with ±180° rotation and ±30° tilt forward/backward. Main circuit terminals accept stranded wire from 2x 0.75 mm² up to 2x 25 mm², or solid wire from 2x 0.5 mm² up to 2x 4 mm² (max 2x 4 mm² solid). AWG equivalents for main contacts are 2x 18 to 2 AWG. Auxiliary and control circuit terminals use the same screw-type format, with solid wire sizes 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², max 2x 0.75–4 mm². Side-by-side mounting is permitted — no spacing required between adjacent contactors, which saves panel width. The contactor is 73 mm wide, 112 mm high, and 115 mm deep. ## Coil and Switching Performance The magnet coil is rated for AC operation: at 50 Hz the holding power is 12.6 VA; at 60 Hz the power factor is 0.37. Coil operating times: pick-up (at AC) 10–30 ms, arcing time 10–15 ms. Rated control supply voltages: 110 V at 50 Hz, 120 V at 60 Hz. Auxiliary contact ratings: per NC contact 40 A, per NO contact 40 A. Switching capacity at various voltages: 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, 3 A at 400 V, 1 A at 440 V. Mechanical life of the contactor is typically 10 million operations. Substance prohibitance per RoHS/REACH applies from 01.05.2012, meaning the contactor complies with the EU RoHS directive for materials restrictions effective that date.","metaTitle":"Siemens 3RT1535-1AK60 SIRIUS Power Contactor, Size S2, 80 A","metaDescription":"Siemens 3RT1535-1AK60 SIRIUS power contactor, Size S2, screw-type terminals, 80 A gL/gG fuse for type 2 coordination.
