2.4.7 Enclosures and mounting accessories
Molded-plastic enclosures (IP55) are available if you want to install circuit
breakers/MSPs as single units. All the enclosures 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 enclosure there are
2 precut openings. All the cable bushings have metric dimensions. The sur-
face casings can be sealed. There is space in the enclosure on the rail for
additional modular terminal blocks.
Widths The widths of the enclosures depend on whether auxiliary releases are used:
• 54 mm: circuit breaker/MSP + side-mount auxiliary contact
• 72mm/82 mm: circuit breaker/MSP + side-mount auxiliary contact+ auxil-
iary release
