Remarks
Note 1.
All indicators, excluding special grade and foreign standard specification indicators comply with the Japanese Industrial Standards relating to direct-acting
electrical indicators and have a JIS mark (excluding LB-8ZNAA, LB-8ZNAV and LB-11ZRMNAA).
Use an AC indicator in combination with an instrument current transformer and an instrument voltage transformer.
