“TEDOM has been using ComAp mains decoupling relays for over 10 years – installing over 1500 units during this time on both new projects and upgrading older installations. MainsPro was first used immediately after the product release as a replacement for the NPU protection unit that we used before. Typical uses for MainsPro include switchboards of cogeneration units and gen-sets operating in parallel with the public distribution network. MainsPro accurately measures and evaluates the essential mains parameters, and provides reliable mains-decoupling protection. It also brings added benefits including excellent usability, possibility of mechanical sealing, a wider range of features and the ability to switch two-set settings via an external contact”
