Product FAQs
5 answersWhat type of panels or equipment is the KHP36175 compatible with?
The KHP36175 is a bolt-on unit mount circuit breaker designed for use in Square D switchboards, industrial enclosures, and motor control centers. It does not fit I-Line panelboards, which require a plug-on mounting style.
Is the Square D KHP36175 still manufactured, or is there a modern replacement?
The KHP36175 is a legacy K-frame circuit breaker. For new installations or direct replacements, Square D recommends the PowerPact J-frame series, specifically the JGL36175, which shares the same 175A rating, 3-pole configuration, and 35kA at 480V interrupting capacity.
What wire sizes and materials are accepted by the lugs on the KHP36175?
The standard lugs on this breaker accept wire gauges from 4 AWG up to 350 kcmil. They are rated for use with both aluminum and copper (Al/Cu) conductors.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) and Instantaneous (I) protection. The thermal element provides fixed long-time overload protection, while the magnetic element can be adjusted to set the instantaneous short-circuit trip threshold.
Can the KHP36175 be used in DC applications?
Yes, in addition to its 600VAC rating, this breaker is rated for up to 250VDC with an interrupting capacity of 10kA, making it suitable for select industrial DC control and distribution circuits.
