That's a 3-pole contactor sized for a 22 A full-load current class motor on a 400 V line, with the electrical life typical of the S0 frame — 10 million operations mechanical, though the electrical life at full AC-3 load will be lower. Short-circuit coordination is specified with two fuse classes: Type 2 coordination requires 35 A gL/gG fuses (the contactor survives the fault essentially undamaged); That's a real decision point for the panel designer targeting a specific SCCR. The contactor carries IP20 on the front (finger-safe when installed in an enclosure) and IP00 at the terminals — meaning the connection points are not touch-protected on their own. RoHS compliance date of July 1, 2006 confirms it meets the original EU RoHS directive. The IEC 81346-2 reference code Q (switching device) is standard for panel documentation. ## Terminal wiring details Main circuit screw terminals accept solid or stranded copper: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x 4 mm². The auxiliary/control circuit terminals take larger wire: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), or max 2x 10 mm². AWG equivalents are listed for both — 2x (16 to 12) and 2x (14 to 10) for mains, 1x 8 for a single conductor.","metaTitle":"Siemens 3RT1026-1AV00 SIRIUS Power Contactor, 3-Pole, S0, 40","metaDescription":"Siemens SIRIUS 3RT1026-1AV00 power contactor, size S0, 3 NO main contacts.
