VAC U80-01 Toroidal Core Fluxgate Residual Current Sensor Ring

VAC U80-01 toroidal magnetic core manufactured by Vacuumschmelze (VAC). The core is a nanocrystalline toroidal ring used in fluxgate differential current sensors designed to detect AC and DC residual currents. Components like this are commonly used inside residual current detection systems for electrical safety devices including EV chargers, industrial power equipment, photovoltaic systems, and protection circuits.

The ring features the VAC logo and the marking U80-01 printed on the housing. The red epoxy coated toroidal core is typical of VAC nanocrystalline cores used in high precision fluxgate sensors.
