Model OVP Over-Voltage Protector by Dairyland Electrical

OVP Overview Designed to address needs for an explosion-proof protection device, the OVP line of products uses solid-state switching components to conduct at very low voltages, providing the most reliable over-voltage protection available to the industry. The OVP is rated for AC fault current and lightning, ensuring peak performance for the product’s long life outperforming other protection products such as spark gap arresters and surge diverters. The OVP was designed and has been tested to meet the requirements for Class I, Division 1 & 2, Group B, C, D classified locations in North America, and for Zone 1 requirements internationally. The model OVP is primarily used in Class I, Division 1 hazardous locations, requiring explosion-proof construction. The OVP was designed and has been tested to meet the requirements for Class I, Division 1 & 2, Group B, C, D classified locations in North America, and for Zone 1 requirements internationally. The model OVP is primarily used in Class I, Division 1 hazardous locations, requiring explosion-proof construction. Note: the OVP is not recommended where steady-state AC voltage exists between the connection points, typically induced AC voltage. Features & Characteristics The only fail-safe "arrester" on the market (i.e., fails shorted). Solid-state design eliminates arcing. Conduction at much lower voltages than gapped arresters. Rated for AC fault current and lightning surge current. Suitable for submersed or above-ground locations. UL, C-UL listed explosion-proof design. Corrosion resistant nickel finish.   Typical Applications Insulated Joint Protection Airport Fueling Systems Isolation / Bonding Decoupling Equipment Grounds
