I-Line Circuit Breakers
PowerPact B-frame circuit breakers are available in I-Line construction for easy installation and removal in I-Line panelboard and switchboard applications.
I-Line circuit breakers use “blow-on” type line side connectors. In case of a short circuit, increased magnetic flux causes the plug-on connectors of the circuit breaker to tighten their grasp on the busbars.
The I-Line connectors and circuit breaker mounting bracket are integral parts of I-Line circuit breakers and cannot be removed or replaced.
I-Line circuit breakers come with aluminum mechanical load-side lugs, or optional copper mechanical lugs, EverLink™ lugs with control wire terminals, or terminal nuts to connect to bus bars or to compression (crimp) lugs.
