That AC-6b utilisation category means it's designed to switch capacitor banks — the inrush current when energising a discharged capacitor can hit 100× the rated current, and a standard contactor's contacts would weld. This one handles the pre-charge surge without sticking. Size S2 frame, screw terminals, with one NO and one NC auxiliary contact built in. The screw terminals take up to 35 mm² cable, and the S2 footprint fits standard DIN-rail mounting in a motor control centre or power factor correction panel. No extra aux block needed for basic status feedback — that 1 NO + 1 NC covers the PLC input and the run-permissive interlock.","metaTitle":"Siemens 3RT2636-1AV03 Capacitor Contactor, AC-6b 50 kVAr","metaDescription":"Siemens 3RT2636-1AV03 capacitor contactor, AC-6b 50 kVAr at 400 V, 3-pole, 1 NO + 1 NC aux, screw terminal, size S2.
