Product FAQs
6 answers
What does the SA suffix indicate on the HDP36125SA catalog number?
The SA suffix designates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely using a control voltage signal.
Are the lugs on the HDP36125SA rated for aluminum conductors?
Yes, the standard factory lugs are dual-rated for both aluminum and copper wire, accepting conductor sizes from 14 AWG to 3/0 AWG.
How is the HDP36125SA mounted in a panel?
This is a unit-mount circuit breaker. It bolts directly to the backpan or mounting plate in industrial control panels and switchboards, rather than plugging onto an I-Line bus.
Can the trip settings on the HDP36125SA be adjusted in the field?
The thermal protection for overloads is fixed, but the magnetic trip for instantaneous short-circuit protection is adjustable to coordinate with other devices in your system.
Is the HDP36125SA suitable for DC circuits?
Yes, it is rated for use in DC applications up to 250VDC, where it provides a 20kA interrupting rating.
Will the HDP36125SA fit in an I-Line panelboard?
No, this is a unit-mount breaker. For an I-Line panelboard, you would need an I-Line version of the PowerPacT H-frame, such as the HDA or HGA series, rather than the HDP unit-mount configuration.
