I-Line™ Circuit breakers
PowerPact H-, J-, and L-frame circuit breakers are available in I-Line construction for easy installation
and removal in I-Line 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 bus
bars. 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 mechanical load side
lugs, or optional terminal nut to connect to bus bars or to compression (crimp) lugs.

Plug-In Circuit Breaker Mounting
The plug-in base is mounted through a panel. The plug-in configuration makes it possible to:
• Extract and/or rapidly replace the circuit breaker without having to touch connections
• Allow for addition of future circuits at a later date
When the circuit breaker is in the connected position, the primary voltage is fed through the circuit
breaker by means of multiple finger disconnects. Control voltage of internal accessories is provided
through secondary disconnects.
Parts of a Plug-In Configuration
• Plug-in Base: The plug-in base provides mounting through a front panel or mounting on rails.
• Disconnects: Provides both primary and
secondary disconnect to the circuit
breaker.
• Safety Trip Interlock: The safety trip
causes automatic tripping if the circuit
breaker is ON before engaging or
withdrawing it; the safety trip does not
prevent the circuit breaker operation, even
when the circuit breaker is disconnected.
• Plug-in Base: The plug-in base provides
mounting through a front panel or mounting
on rails.
• Mandatory short terminal shields.
