The coil is 24 V AC, 50 Hz only. It has three main NO contacts and one auxiliary NO contact, all screw-type terminals. The AC-1 resistive rating is 35 A at 400 V, but the part is specifically designed for AC-6 capacitor switching — that's the rating that governs selection. The 25 kVAr figure at 400 V matches common power-factor correction banks in industrial distribution panels. Side-by-side mounting is permitted with no spacing required. Dimensions are 45 mm wide, 100 mm high, 135 mm deep — the depth is the main space consideration in a shallow enclosure. Operating ambient is -25 to +60 °C.","metaTitle":"Siemens 3RT1627-1AB01 Capacitor Contactor, 25 kVAr, 24 V AC,","metaDescription":"Siemens SIRIUS 3RT1627-1AB01 capacitor contactor, AC-6 rated 25 kVAr at 400 V, 24 V AC 50 Hz coil, 3-pole, size S0.
