TK406005205 CURRENT TRANSFORMER 600/5A, 40mm, CL 0.5, 5VA
The TK406005205 (TK 40 Series) is a high-precision low-voltage measuring current transformer engineered for high-accuracy energy metering, power monitoring systems, and panel instrumentation. Featuring a 600/5A transformation ratio, it converts primary AC currents up to 600 Amps down to a standard 5 Amp secondary output with Class 0.5 precision and an enhanced 5VA rated burden capacity. Housed in a self-extinguishing polycarbonate enclosure with a wide 40mm aperture (designed for $40 \times 10\text{ mm}$ busbars or round insulated conductors), this CT ensures exceptional electrical insulation, thermal stability, and vibration resistance for commercial and industrial switchboards.
