Product FAQs
7 answersWhat type of panelboards accept the PJA36060 circuit breaker?
The PJA36060 features an I-Line style plug-in connection, making it compatible with Square D I-Line panelboards and switchboards.
What wire sizes are compatible with the lugs on this breaker?
The standard lugs accept three AWG 3/0 to 500 kcmil aluminum or copper conductors per phase.
What protection does the LI trip function provide?
The LI designation indicates the solid-state trip unit provides Long-time (L) overload protection and Instantaneous (I) short-circuit protection.
How is the I-Line connection installed on the busbar?
The I-Line plug-in design uses a stab-on connection that mounts directly onto the busbars of an I-Line panelboard or switchboard. It is secured by a mounting bracket, allowing for faster installation compared to traditional unit-mount breakers.
What does the PJA prefix indicate in the catalog number?
The PJA prefix designates a Square D PowerPacT P-Frame molded case circuit breaker with a J-level interrupting rating and an I-Line plug-in connection.
Does the PJA36060 include ground-fault protection?
No, this breaker is equipped with an LI trip unit, which provides Long-time and Instantaneous protection but does not include Ground-fault (G) sensing. If equipment ground-fault protection is required, a breaker with an LSIG trip unit must be used.
What is the advantage of the solid-state trip unit on the PJA36060?
The solid-state electronic trip unit provides highly accurate and repeatable trip curves compared to traditional thermal-magnetic breakers, ensuring precise overcurrent and short-circuit protection for the electrical system.
