Description
Built for heavy-duty industrial environments, the 25A H-Frame MCCB provides fixed thermal and magnetic trip functions. It handles up to 600VAC while maintaining a compact footprint. The unit-mount configuration utilizes standard lugs for secure wire terminations in control panels. Facilities can utilize this model to replace aging FAL36025 units with minimal retrofit effort. Operators benefit from the integrated Visi-Trip handle, which clearly distinguishes tripped states.Specifications

Product FAQs
8 answersWhat is the recommended tightening torque for the line and load lugs on the HDL36025?
The standard lugs on this breaker should be torqued to 44.3 lb-in (5 N.m) when terminating 14 to 3/0 AWG aluminum or copper conductors.
What are the fixed magnetic trip settings for this 25A H-Frame breaker?
The HDL36025 features a fixed magnetic hold current of 350A and a fixed magnetic trip current of 750A.
Can I add internal accessories like shunt trips to the HDL36025?
Yes, PowerPacT H-Frame breakers support field-installable internal accessories, including shunt trips, undervoltage releases, and auxiliary switches. These install directly into the accessory compartments located behind the front cover.
Can the HDL36025 be used to replace older FAL series circuit breakers?
Yes, PowerPacT H-Frame unit-mount breakers are the modern replacement for legacy Square D FAL series breakers, such as the FAL36025. Minor mounting or footprint adjustments may be required when retrofitting older control panels.
Is this breaker compatible with Square D I-Line panelboards?
No, the HDL36025 is a unit-mount breaker designed for backpan installation in industrial control panels and enclosures. For I-Line panelboards, an HDA, HGA, or HJA series breaker with an I-Line mounting bracket is required.
How does the HDL36025 indicate a tripped condition?
This breaker features a Visi-Trip handle mechanism. When a fault occurs, the handle snaps to a distinct center position between ON and OFF, allowing personnel to quickly identify the tripped circuit.
Can this thermal-magnetic breaker be used in DC circuits?
Yes, the HDL36025 is rated for use in DC applications up to 250VDC, providing an interrupting capacity of 20kAIC.
Are the line and load lugs removable on the HDL36025?
Yes, the factory-installed mechanical lugs (AL150HD) can be removed to accommodate other termination methods, such as compression lugs or power distribution connectors, depending on your panel requirements.
