10mm Opening, Three Phase, Panel Mounted Current Transformer

The TA7161 series of three phase, toroidal, panel mounted current transformers provide highly accurate, non-contact step-down transformation of the AC primary current to a level appropriate for micro-processor based circuits.
The TA7xxx series are designed for applications where a high over-current capability is a desirable feature. Typically used in 380VAC or 660VAC motor protection circuits.
