For resistive loads (AC-12) the maximum operating current is 10 A. At 690 V it is rated for 11 kW (AC-3). Mechanical endurance is listed at 10 million operating cycles, typical for this class of IEC contactor. Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (0.25–2.5 mm²), 2x (1–2.5 mm²), 2x (2.5–6 mm²), or a single 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), and 1x 8. Pollution degree 3 (industrial environment). ## Protection and coordination For Type 1 coordination (contactor may need replacement) the fuse can be up to 63 A gL/gG.","metaTitle":"Siemens 3RT1025-3AL16-ZX95 SIRIUS Power Contactor, S0, 3NO,","metaDescription":"Siemens 3RT1025-3AL16-ZX95 SIRIUS power contactor, size S0, 3 NO main contacts, 230V 60Hz coil.
