At 40 °C ambient, a single 6 mm² conductor is permitted; at 60 °C, a single 10 mm² or 2×6 mm². The 45 mm width and 135 mm height fit standard S0 contactor spacing on the DIN rail. Depth is 155 mm, which includes the arc chamber and terminal clearance — account for this when laying out the gland plate and door swing. ## Operating envelope and switching frequency The switching frequency for capacitor duty is 180 operations per hour at 230 V, 400 V, 480 V, 500 V, and 600 V, dropping to 150 ops/h at 690 V. Auxiliary contact blocks are attachable (0 supplied) — the contactor has no built-in aux contacts. Add a SIRIUS side-mount block if feedback to the PLC or status indication is needed.","metaTitle":"Siemens 3RT2625-1AK65 SIRIUS Capacitor Contactor","metaDescription":"Siemens 3RT2625-1AK65 SIRIUS capacitor contactor, S0 size, 110 VAC 50 Hz coil, screw terminals.
