Feature

Able to change direction of installation leg to 90 degree.
Able to use 600V vinyl wire for primary conductor.

Caution

Power frequency withstand voltage/lightning impulse withstand voltage will be indicated for withstand voltage.
Product mass could be varied by variation of core characteristic.

Rated Primary Current (current transformation ratio)

Window type current transformer has flexibility in application and is reasonable because of its usage for several rated primary current by changing primary conductor.

[CASE: Current transformation ration100/5]
Number of penetration: 1turn ..........Rated primary current 100A
Number of penetration: 2turns..........Rated primary current 50A

* CTC-N5R、CTC-N15R、CTC-N40R are manufactured, with JIS Standard (JIS-C1731).
