MagneX™ Interupters

A compact way to protect distribution transformers from overload and faults, and provide a reliable method for switching transformers "on" or "off".


The MagneX™ Interrupter is an overcurrent protective device that protects distribution transformers from damaging overloads and secondary faults, and is also used for switching the transformer “on” or “off.” As a transformer protective device, the MagneX Interrupter combines safety and efficiency with economic operation.

It is an integral assembly, which does not use a troublesome linkage or require calibration, making installation and operation fast and trouble free. The housing is made of an ultraviolet stabilized, high-strength, glass-filled thermoplastic material. The operating shaft is sealed against leakage with a double-Viton® O-ring seal.
