Tables of insulation distances
Notes:
The figures are for lower breakers.
For front connection breakers, insulate all exposed conductors of the line side until the breaker end. If interpole barriers are packed, be sure to use the barriers; more over, insulate all exposed
conductors by insulating tape or the like so that the tape overlaps with the barriers.
* If using extension bars (optional), ensure the insulation distance specified for the application.
DIRECTION OF POWER SUPPLY
The breakers are available for normal connection by default. Reverse connection is optional.
