More information
Space requirements when installing LV HRC fuse bases
1)
This measurement specifies the required overall mounting depth with base
d and the overall mounting height h.
2)
Placing an additional base on the barrier and plug-on part does not
increase the distance, rather the bases lie flat directly on top of one
another.
3)
If the bases are installed directly on a side wall in the distribution board,
one spacer part can be broken off. This would reduce the distance
measurement.
