About This Product

■Features of zero-phase current transformer

- We have a wide variety of models for low pressure and high pressure, so you can choose according to your application. ・For low pressure only, there are BM and SM series models with excellent balance characteristics. -Uses a permalloy iron core with excellent properties.

■Model selection

For ZCTs with primary conductors, it is determined by the rated current, and for feed-through types, it is determined by the diameter of the wire that can pass through the ZCT without exceeding the rated current of the ZCT. For high-voltage power receiving applications, it may be determined by the overcurrent strength in the event of a short circuit accident. If the inrush current, etc. significantly exceeds the rated current due to the nature of the load, it is safer to determine the current value with balanced characteristics.

■Features

・Zero phase current transformer penetration type for low voltage. ・Excellent balance characteristics. - Compliant with "JIS C 8374 Earth Leakage Relay" standards.
