Legrand IME, Current Transformer for Low Voltage Grid Measurements for Push Through Busbar, Primary Current: 150 A, Secondary Current: 5 A, Cable Cross Section: 27 mm², Accuracy Class: Kl 0.5-1, TA32750C150

Low voltage converters: In industry, current transformers are the first link in the measuring chain for the detection of electrical sizes. By measuring the secondary current, they allow precise conclusions on the flowing current in the primary circuit. Their use is sufficient from simple devices such as For example, analogue displays, to highly complex devices, such as transformers, energy meters, multifunction indicators, and ultimately also in monitoring systems.
