Molded-plastic housings (IP 55) are available if you want to install circuit
breakers as single units. All the housings are equipped with neutral and
ground terminals. Above and below are two openings that can be knocked
out for cable glands. On the back of the housing there are 2 precut open-
ings. All the cable bushings have metric dimensions. The surface casings
can be sealed. There is space in the housing on the rail for additional modu-
lar terminal blocks.
