Schneider Electric 7RL-501B Current Transformer

Schneider Electric's 7RL-501B current transformer is a non-ANSI rated, window-type instrument transformer with a 500:5 ratio for accurate current sensing in industrial power systems. It supports 50 Hz to 400 Hz operation and carries a 600 V insulation class, enabling use in distributions up to 600 V. At full scale, the secondary delivers 5 A when the primary current is 500 A, and it carries a 25 VA burden rating, making it suitable for metering and protection relays without excessive loading. The device features a 63.5 mm window opening to accommodate common conductors in panel installations, aligning with Schneider Electric's Square D line for reliable interoperability in dedicated electrical cabinets and switchgear.
