Section 5: Fixed circuit breaker
General
Section 3 discussed topics and features common to all IZM circuit
breakers, no matter what the mounting configuration. In this section,
features unique to the fixed configuration not covered elsewhere are
covered. Drawings and dimensions associated with all fixed circuit
breakers and any appropriate primary bus connections can be found
in a separate document. The installation of a fixed circuit breaker
was discussed in Section 2. If necessary, review that information,
since it will not be repeated here.
Fixed circuit breaker dimensions
The standard fixed circuit breaker is supplied with horizontally
mounted primary connections (
). Optional vertical primary
adapters are available for different bus configurations.
