I-Line Breaker Style Bus Plugs

These bus plugs are for use on Square D's I-Line series busway.  The bus plugs will plug into I-Line I and I-Line II series plug-in bus duct.  

A Square D circuit breaker provides the over-current protection.  Upon a fault the circuit breaker will trip, interrupting the flow of electricity across all three phases.  

An advantage of a circuit breaker bus plug is the ability to restore power after the breaker has tripped by re-setting the circuit breaker.  For setups that experience occasional power issues this may save time and hassle, compared to changing out fuses.

The bus plugs are available with or without a neutral, as well as, with or without a ground tab.

The bus plugs are sized according to the circuit breaker frame by amps:

• F frame circuit breakers - 15 amps to 100 amps
• K frame circuit breakers - 125 amps to 250 amps
• L frame circuit breakers - 250 amps to 400 amps
• M frame circuit breakers - 500 amps to 1000 amps
• P frame circuit breakers - 1000 amps to 1600 amps
