RONK BLOCKER Stray Voltage Isolator

The RONK BLOCKER Stray Voltage Isolator provides secondary fault protection to secondary grounding systems. Best suited to protect sensitive locations like homes, swimming pools, fountains, swine, dairy and poultry farms.

An off-site stray, or neutral-to-earth (NE), voltage can result from primary neutral currents, off-site faults, or marginal groundings. The RONK BLOCKER is designed to reduce the off-site contributions to the stray voltage, allowing the utility to focus on the on-site sources. This device operates on the importance of magnetic saturation and does not depend on external controls or internal logic signals. Therefore, it reacts without delay providing immediate and continuous protection at all times.

RONK Electrical is known for manufacturing a variety of power products. Some include, transfer switches, docking stations, and outdoor equipment enclosures. RONK has expanded the market reach beyond the serving industries such as the agriculture industry, oil and gas, water and wastewater, utilities and electrical co-ops, healthcare, government, HVAC and generator systems.
