CURRENT TRANSFORMER TK 30N-200/5 A, 25 VA, CL0.5 VTEKE
The TK 30N 200/5A is a low-voltage measurement current transformer featuring high precision Class 0.5 accuracy and a 2.5VA rated burden capacity. Designed with a 30mm window aperture (suitable for $30 \times 10\text{ mm}$ busbars or round cables), it steps down 200A primary currents to a standard 5A secondary signal suitable for energy meters, digital power monitors, and panel instrumentation. Housed in a self-extinguishing polycarbonate body with integrated sealable terminal covers, it ensures reliable insulation, high thermal endurance, and vibration resistance for switchgear and control panels.
