Product FAQs
8 answersWhat does the "D" in the HDP36020 catalog number signify?
The "D" indicates the interrupting rating of the breaker, which provides 18kA of fault clearing capacity at 480VAC.
Can the HDP36020 be installed in a Square D I-Line panelboard?
No. The HDP36020 is a unit-mount, bolt-on circuit breaker. For I-Line panelboard installations, an HDA or similar I-Line configured breaker is required.
What replacement lug kit is compatible with the HDP36020?
This breaker uses the AL150HD mechanical lug kit, which accepts 14 to 3/0 AWG aluminum or copper conductors.
What does the "LI" trip function code mean on this breaker?
The "LI" designation means the thermal-magnetic trip unit provides Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits.
How can I manually test the mechanical trip linkage on this breaker?
PowerPacT H-Frame breakers feature an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the internal operating mechanism is functioning correctly.
How do I properly reset the HDP36020 after a fault trip?
When the breaker trips, the handle moves to a center position to provide visual indication. To reset the breaker, push the handle to the extreme "OFF" position to re-latch the mechanism, then push it to the "ON" position.
What type of equipment is the HDP36020 designed for?
The unit-mount design and 600VAC rating make the HDP36020 suitable for industrial control panels, switchboards, and custom power distribution equipment that accommodate H-Frame breakers.
How does the HDP36020 limit peak current during a short circuit?
PowerPacT H-Frame circuit breakers are equipped with dual-break rotating contacts. This design rapidly repels the contacts during a fault, extinguishing the arc early and reducing the amount of peak let-through current.
