Product overview
Busbar split-core current transformers
Fig. 8: SCT71xx
Like the SCT6xxx series, the SCT7xxx busbar split-core current transformers for primary currents up to
5000 A can be retrofitted to existing systems with no great mounting effort. From 500 A, there is a choice
between accuracy class 0.5 and 1 for each primary current. The SCT7105-0100 and SCT7105-200 current
transformers support accuracy class 3.
