Product FAQs
6 answersWhat type of panelboards is the KH36175J compatible with?
The KH36175J is a legacy K-Frame plug-in circuit breaker designed exclusively for use in Square D I-Line panelboards and switchboards.
What is the modern replacement for the KH36175J?
The KH series is a legacy product. Facilities looking to modernize or replace this unit can cross-reference it to the newer Square D PowerPact J-Frame series, such as the JJA36175, which also mounts in I-Line panelboards.
What wire sizes are accepted by the lugs on the KH36175J?
The factory lugs on this 175A breaker accept aluminum or copper conductors ranging from 4 AWG to 350 kcmil.
Where can I find the correct lug torque specifications for this breaker?
To ensure a safe and code-compliant installation, always refer to the torque values printed directly on the faceplate of the circuit breaker or the documentation provided with your I-Line panelboard.
What does the LI trip function mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. The thermal element is fixed, while the magnetic instantaneous trip is adjustable.
What are the safety requirements for installing this I-Line breaker?
For safety and compliance with NFPA 70E standards, you must completely de-energize the panelboard or switchboard before installing or removing any I-Line plug-in circuit breakers.
