Product Description

The YDBH0.66-30I-A-250/5A is a compact Current Transformer 250/5A designed for precise 0.66kV CT Metering in low-voltage power distribution systems. It features a single input rated at 250A primary current with a 5A secondary output, directly compatible with standard metering modules or protective relays. Operating within a voltage range of 0.66kV and a temperature range of -25°C to +70°C, this CT is ideal for energy management, industrial automation, and smart grid applications. Its robust construction ensures high accuracy (±1%) and durability in harsh environments. While lacking integrated communication interfaces or display screens, it excels in simplicity and reliability. The device requires no external power source (battery-free) and is optimized for easy installation. Detection distance refers to its seamless integration into busbar or cable setups without proximity limitations. Its primary drawback is the absence of advanced connectivity, relying on external systems for data transmission. Designed for efficiency, this transformer minimizes energy losses and supports critical load monitoring in commercial and industrial sectors.
