SIRIUS size S0 power contactor — 3RT6026-1AB00
It carries an AC-3 rated voltage maximum of 690 V, and at 400 V 60 °C it is rated for 23 kW motor power — covering common 400 V three-phase induction motors up to that load. The contactor mounts via screw fixing or snap-on onto 35 mm standard mounting rail per DIN EN 50022, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward, giving panel builders flexibility in tight enclosures.
At 400 V 60 °C the 23 kW figure matches a typical 30–32 A motor full-load current, so this contactor fits a 30 hp (22 kW) IEC motor or a 25 hp NEMA motor on a 400 V supply. The AC-3e maximum switching rate of 750 operations per hour means it can cycle a motor start every ~5 seconds continuously — fine for conveyor or pump cycling, but not for high-speed indexing. The auxiliary contact ratings (6 A at 24 V, 10 A at 230 V) cover PLC-level signals and small relay coils; the 24 V 6 A rating is enough for a handful of 24 VDC solenoids or indicator lamps. The substance prohibitance date of 05/01/2012 indicates RoHS compliance per EU Directive 2011/65/EU, with no exemptions claimed for this variant.
Both the main current circuit and the auxiliary/control circuit use screw-type terminals. The main terminals accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) — the larger cross-section is useful for paralleling the supply feed. Minimum permissible conductor size at 40 °C and 60 °C is 10 mm², which is the smallest wire that should be used for the power path. For AWG, the main terminals accept 2x (16 to 12) or 2x (14 to 8).
