AMAC Distribute the solid-state RustrolĀ® Cathodic IsolatorĀ® - an essential component for safely isolating cathodically protected structures.
The Cathodic IsolatorĀ® effectively blocks the protective DC current needed for cathodic protection while providing a grounding path for; AC fault currents, lightning, induced AC, power switching surge currents or any other electrical disturbance. The result: Personnel and Equipment are safely protected against shock hazards.
AC Fault Currents
RustrolĀ® Systems are designed to protect personnel and equipment from electrical disturbances. RustrolĀ® Systems effectively block cathodic protection DC voltages; all other electrical disturbances are freely conducted to ground, such as:
Mitigation of induced AC Voltages
Cathodic IsolatorĀ® is available in common models with rated A.C. fault current exposure parameters in accordance with the attached Specification Sheet CI-01. Voltage thresholds and other operating parameters are to be specified by the customer.
Benefits of the Cathodic Isolator: Solid-state construction
