Installation in Equipment
Power from the Top or Bottom
PowerPact H-, J-, and L-frame circuit breakers with factory-sealed trip units can be supplied from
either the top or the bottom without any reduction in performance. This capability facilitates connection
when installed in end-use equipment.
All connection and insulation accessories can be used on circuit breakers supplied either from the top
or bottom.
Weight
The table below presents the weights of the circuit breakers and the main accessories, which must be
summed to obtain the total weight. The values are valid for all performance categories.
Safety Clearances and Minimum Distances
General Rules
When installing a circuit breaker, minimum distances (safety clearances) must be maintained between
the device and panels, bars and other protection devices installed nearby. These distances, which
depend on the voltage, are defined by tests carried out in accordance with UL standards.
If installation is not checked by type tests, it is also necessary to:
• use insulated bars for circuit-breaker connections
• segregate the busbars using phase barriers
For PowerPact H-, J-, and L-frame devices, terminal shields and interphase barriers are recommended and
may be mandatory depending on the operating voltage of the device and type of installation (unit-mount,
drawout, etc.).
Power Connections
The table below indicates the connection requirements for PowerPact H-, J-, and L-frame devices to
ensure insulation of live parts for the various types of connection.
• unit-mount devices with front connection or rear connection
• plug-in or drawout devices.
Connection accessories such as crimp lugs, terminal extensions (straight, right-angle, double-L and
45°) and spreaders are supplied with interphase barriers. Long terminal shields provide a degree of
protection of IP40 (ingress).
