External neutral current transformer from Schneider Electric, 150/250A configuration. Used in electrical systems to measure neutral current, typically for protective relays or monitoring applications. Supports analytics and fault detection.
Primary rated current: 150/250A selectable. Secondary output: standard 5A. Core-type design for improved accuracy over long periods of operation, but bulky form factor compared to compact units. Installation requires proper alignment on the busbar or cable — detachable base simplifies mounting process.
Housing material resistant to high-temperature environments (up to ~70°C continuous). Dielectric strength meets IEC standards — rated at >3 kV RMS between primary and secondary windings for safety isolation.
