The coil pulls in at 0.8 to 1.1 times rated voltage at 50 Hz, so it's tolerant of a sagging line. Front face is IP20, terminals are IP00 — standard for panel interior where the enclosure provides the outer seal. Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to 2x 4 mm² solid max. For stranded wire, the range is 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²), with a single 10 mm² max. AWG equivalents are 2x (16 to 12) solid or 2x (14 to 10) stranded, single 8 AWG. That's enough for the full rated current without pigtailing.","metaTitle":"Siemens 3RT1025-1AB00-ZW97 SIRIUS Power Contactor, 24V 50Hz","metaDescription":"Siemens SIRIUS 3RT1025-1AB00-ZW97 power contactor, size S0, 3 NO main contacts, 24V 50Hz coil.
