Product FAQs
5 answersWhich Siemens and ITE panelboards are compatible with the JKL3B175 circuit breaker?
This bolt-on J-Frame breaker is designed for installation in Siemens and ITE P4, P5, S5, and CDP-6 panelboards.
What wire sizes are accepted by the standard lugs on this breaker?
The factory lugs accommodate wire sizes ranging from 4 AWG to 300 kcmil and are rated for use with both copper (Cu) and aluminum (Al) conductors.
What does the LI trip function code mean for the JKL3B175?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection for standard overloads and Instantaneous (I) protection for short circuits.
How does the adjustable magnetic trip feature work on this J-Frame breaker?
While the thermal overload protection is fixed at 175 amps, the magnetic trip element is adjustable. This allows electricians to tune the instantaneous short-circuit response threshold to accommodate specific inrush currents or coordination requirements.
Does this breaker require a specific mounting hardware kit?
As a bolt-on breaker, it mounts directly to the bus bars of compatible panelboards. Depending on the specific panelboard model, a dedicated mounting strap or connector kit may be required if one is not already present on the bus.
