The 35 A rated value and 3 NO main contacts handle the switching, while the single NO auxiliary contact provides feedback or interlock. The coil is 220 V AC at 50 Hz and 240 V AC at 60 Hz, drawing from a 50/60 Hz control supply. The 3RT1627-1AP61 is a phased-out product. The preferred successor is the SIRIUS 3RT2627-1AP65, which should be verified for electrical and mechanical interchangeability before specifying into a new design. ## Integration Notes Mounts on a 35 mm DIN rail per DIN EN 50022 with a 45 mm width, 100 mm height, and 135 mm depth. The IP20 front and IP00 terminal area mean the panel door must provide the environmental seal; the contactor itself is touch-safe on the front but the terminals are exposed. Side-by-side mounting is allowed — no derating required for adjacent units.","metaTitle":"Siemens 3RT1627-1AP61 Capacitor Contactor, 35 A, AC-6, 220 V","metaDescription":"Siemens SIRIUS 3RT1627-1AP61 capacitor contactor, 35 A rated, AC-6 duty for 25 kVAr at 400 V. 220 V AC coil.
