Product FAQs
9 answersWhat does the "P" in the HDP36045 catalog number signify?
The "P" indicates the breaker's connection type. It features a terminal nut on the line side for fixed busbar connections and mechanical lugs on the load side.
What are the magnetic trip settings for the HDP36045?
This 45A thermal-magnetic breaker has a fixed magnetic hold current of 400A and a fixed magnetic tripping current of 850A.
Which mechanical lug kit is standard on the load side of this breaker?
The HDP36045 comes standard with the AL150HD mechanical lug kit on the load side, which accepts 14 AWG to 3/0 AWG copper or aluminum conductors.
Can I install the HDP36045 in an I-Line panelboard?
No. The HDP36045 is a unit-mount circuit breaker designed for individual enclosure or backpan mounting with a busbar connection on the line side. For an I-Line panelboard, you need the I-Line equivalent, catalog number HDA36045.
What is the modern replacement for the legacy FAP36045 circuit breaker?
The HDP36045 is the direct PowerPacT H-frame replacement for the legacy Square D FAP36045. Both feature a 45A rating, 3 poles, and a terminal nut line-side connection.
What is the recommended tightening torque for the load-side lugs on the HDP36045?
For the standard load-side lugs, the recommended tightening torque is 44.3 lb-in (5 N.m) for 14 to 10 AWG conductors, and 124 lb-in (14 N.m) for 8 to 3/0 AWG conductors.
Is the HDP36045 suitable for reverse-feed applications?
Yes. Because it uses a standard fixed thermal-magnetic trip unit without electronic components that require directional power, the HDP36045 is suitable for reverse-feed applications.
Is the HDP36045 100% rated for continuous loads?
No. The standard HDP36045 is an 80% rated circuit breaker. For continuous loads lasting three hours or more, the continuous current should not exceed 36A (80% of its 45A rating).
What is the interrupting capacity (AIC) of the HDP36045 at 600VAC?
While rated for 25kA at 240VAC and 18kA at 480VAC, the HDP36045 has an interrupting capacity of 14kA when used in 600VAC systems.
