- The load was applied from +50mm point to the specimen with tightening all the screws of the bottom mounting in order to measure bending strength.
- Creepage distance shows the length from the upper end to the bottom end along the fin surface.
- ※=reference value
- The above items are designed to be installed in general power switchboards and not fit to be exposed to insulation gas.
