Introduction
The JP Series split-core current transformers are specially designed to facilitate both new and retrofit installations in electrical systems. Featuring an easily opened split-core design, they can be installed without disconnecting cables or opening busbar circuits. Unlike conventional current transformers, which require the primary circuit to be interrupted during installation, the JP Series can be installed quickly and conveniently without interrupting the power supply, significantly reducing installation time and costs.
Features
- Bus-bar mounting design.
- Very easy to mount, especially installing Ct on existing bus-bar or cable system.
- Wide inner window, allowing clamping of big cables or bus-bar.
- Wide range of sizes to accommodate all the existing installations, wide range ratio for each size.
