Key Engineering Features & B2B Applications
High Measurement Accuracy
Class 1 accuracy ensures precise current transformation, making it ideal for electrical measuring instruments, digital panel meters, and energy monitoring units.
Superior Ring Geometry
Seamless toroidal core winding eliminates mechanical vibration, audible hum, and magnetic field leakage, providing enhanced reliability in noise-sensitive switchgears.
Robust Dielectric Insulation
Factory-tested at 2 kV HV dielectric isolation between primary and secondary circuits, guaranteeing compliance with global electrical safety directives.
Flexible Flying Lead Wire
Features durable Class F insulated copper windings paired with clearly color-coded flying lead wires (Red-start / Black-end) for straightforward installation.
Custom Engineering & Global Compliance: Non-standard current ratios, specific VA burdens, and custom dimensioning can be custom-engineered to meet specific OEM technical specifications. Due to continuous research, material upgrades, and quality optimization, product dimensions are subject to technical confirmation upon order approval.
