RS PRO Current Transformer, 21 x 10 mm diameter, 100 A Input, 5 A Output, 100:5
You can reduce the amperage of an electrical current using this RS PRO current transformer. The small but powerful device clips onto a bus bar or panel for quick and easy installation to your system. You'll generally find this component in industrial settings whether it's a power distribution network, telecommunications exchange or engineering plant.
This current transformer comes in hardwearing polycarbonate casing, so it's tough enough to withstand the bumps and scrapes of daily life. This product has an Ingress Protection (IP) rating of IP20, so it's protected against touch with fingers, as well as dust and objects over 12 mm in size. You can use it in freezing and hot weather, as it has an operating temperature range of -5°C to +55°C.
