Screw terminals on both the main current circuit and the auxiliary/control circuit. AWG equivalent 2x (16…12) or 2x (14…8). Minimum permissible conductor at 40 °C and 60 °C is 10 mm². ## AC-3 motor switching — 690 V ceiling, 23 kW at 400 V Rated insulation voltage 690 V, with AC-3 and AC-3e maximum operating voltage both at 690 V. Motor power at 60 °C ambient: 13.3 kW at 230 V, 23 kW at 400 V, 40 kW at 690 V. That is the continuous motor load it handles in a warm enclosure without derating. Switching frequency limits: 1 000 ops/h at AC-1 max, 750 ops/h at AC-3/AC-3e max, 250 ops/h at AC-4 max, and 1 500 ops/h at DC. The DC rating of 1 500 ops/h reflects the absence of AC arc extinction constraints — useful for DC load banks or battery switching. ## Active production — quoted to order Auxiliary switch add-on supported (product extension auxiliary switch: Yes). The S0 frame accepts the standard SIRIUS add-on blocks without extra DIN space. If your application needs early break or late make contacts, the add-on kit snaps onto the front without rewiring the main terminals.","metaTitle":"Siemens 3RT6026-1BW40 SIRIUS Contactor, S0, 690 V AC-3","metaDescription":"Siemens 3RT6026-1BW40 SIRIUS power contactor, S0 frame, rated 690 V AC-3/AC-3e max, 45 mm wide, screw terminals.
