MainsPro - Mains Decoupling Relay
Are you generating power in parallel to the mains?
You will need ‘loss of mains’ protection.
Essential to avoid supplying your electricity into an islanded grid, leading to possible equipment damage or safety issues.
The solution is MainsPro, the new microprocessor based mains decoupling relay from ComAp, which offers unequalled mains protection for a wide range of mains connected applications. These include generator sets and renewable energy sources such as photovoltaic plants, wind turbine an other forms of micro cogeneration.
With MainsPro, no special knowledge is needed for installation and no additional units are required, making the ideal solution for both untrained personnel and professionals alike. The unit is designed to fully comply with Utilities’ connexion requirements and statutory codes, offering a high level of protection and safety when working in parallel to the mains.
Reduces your costs for installation and commissioning workload expenses.
