Molded case circuit breakers or supplementary motor operators or front mounted rotary
operators for molded case circuit breakers are often installed in cubicles or distribution
boards in such a way that only the operating device is directly accessible. Busbars, cables
and the termination area of the molded case circuit breaker are covered by metal or plastic
plates in order to prevent direct contact with live components. The cubicle door itself is often
designed as a protective cover.
Cutouts must be made in these covers
● in order to allow access to control elements,
● which are designed to prevent direct contact with cables, and
● which are large enough in size that the cover can be closed easily.
All these requirements necessitate gap dimensions of a few millimeters between the cutout
and the unit.
Escutcheons are installed in cases where the gap size needs to be minimized and the gaps
covered. The use of escutcheons makes for a clean-lined, attractive cubicle front face and
provides a higher degree of protection (IP30).
