Compact NSX circuit breakers can be supplied from either the top or the bottom, even when equipped with a Vigi add-on, without any reduction in performance. This capability facilitates connection when installing in a switchboard. All connection and insulation accessories can be used on circuit breakers supplied either from the top or bottom.

All R, HB1, and HB2 circuit breakers are restricted for use as a line-load connection. They can not have power fed into the bottom of the circuit breaker. They will be marked with Line and Load markings
