4NC6015-0SB00 SIEMENS

The 4NC6015-0SB00 is a high-precision current transformer manufactured by Siemens. It is designed for accurate measurement of alternating current in electrical systems. This transformer has a primary current rating of 150A and a secondary current rating of 5A. It belongs to Class 0.2s, indicating its high accuracy level, making it suitable for revenue metering and protection applications. The transformer is designed to handle a specific burden or load, measured in VA (Volt-Amperes). The core material and winding design are optimized to minimize errors and ensure reliable performance. The 'brown' designation may refer to the color of the transformer's casing or a specific terminal marking. This current transformer provides galvanic isolation between the primary and secondary circuits, enhancing safety. It is typically used in conjunction with measuring instruments, protective relays, and other devices that require accurate current information.
