TE Connectivity 5ASFT-101 NSNBC01 Transformer

TE Connectivity Crompton Instruments' 5SFT-101 current transformer is a window-type CT designed for direct primary current sensing in metering and control panels. It delivers a 100:5 A ratio with a 2 VA burden rating, operates from 50 Hz to 400 Hz, and features a 40 mm window opening for a single primary conductor. The unit is feet-mounted and terminates with brass studs 8-32 UNC (typically supplied with flat and lock washers and nuts) for secure, field-attachable connections; weight is about 3.5 lb. Typical applications include energy metering, protective relays, and power-monitoring deployments where isolated current measurement is required without interrupting the circuit.
