Mounting into industrial control panels and enclosures, the Square D HLL36060 provides essential 60A protection for demanding commercial applications. This 3-pole PowerPacT H-Frame breaker serves as the official replacement for the discontinued FCL36060 model, featuring line and load lugs that accommodate 14-3/0 AWG wire. Equipped with an adjustable magnetic trip unit, it handles up to 100 kAIC at 480VAC and includes a Visi-Trip indicator to quickly identify circuit interruptions.
What is the direct replacement for the legacy FCL36060 circuit breaker?
The Square D HLL36060 PowerPacT H-Frame breaker is the official replacement for the discontinued F-Frame FCL36060 model. Note that the H-Frame has different physical dimensions, so mounting modifications may be required.
What does the "L" in the HLL36060 part number signify?
The "L" indicates the interrupting rating class of the breaker. For the PowerPacT series, the L-class provides a high interrupting capacity of 125 kAIC at 240VAC and 100 kAIC at 480VAC.
Can the HLL36060 circuit breaker be reverse fed?
Yes. Because this breaker uses a thermal-magnetic trip unit, it is suitable for reverse-fed applications in industrial control panels and enclosures.
What is the standard lug kit for the HLL36060 circuit breaker?
The standard mechanical lug kit for this breaker is the AL150HD, which accepts one 14 to 3/0 AWG aluminum or copper wire per terminal.
How does the LI trip function operate on the HLL36060?
The LI designation means the breaker provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. On this specific model, the thermal (overload) setting is fixed, while the magnetic (instantaneous) setting is adjustable.
Does the HLL36060 include a push-to-trip button?
Yes. Like all PowerPacT circuit breakers, it features an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
