AKH-0.66-II is a square-aperture, through-type current transformer built for crowded switchboards. Its glass-fiber reinforced housing slips straight over 1-6 rectangular bars or bundled cables up to 260 mm wide, eliminating the need for dismantling bus-work during retrofits. Offered in ratios from 100/5 A to 6300/5 A and accuracy classes 0.2, 0.5 or 1, the core delivers 5 VA-30 VA burden capacity while keeping linearity within ±0.2 %. A 3 kV/1 min withstand and –30 °C to +70 °C rating let it ride out harsh motor-control centres, photovoltaic combiners or shipboard panels. Two M5 studs or DIN rail clips provide vibration-proof mounting in any orientation, and the 45 mm depth preserves precious cabinet space. CE-marked to IEC 61869-2, the transformer feeds meters, relays or PLCs with a clean 5 A signal, turning high primary currents into safe, measurable data without copper work or shutdown.
