Product FAQs
7 answersWhat does the "4" at the end of the HDA260454 catalog number indicate?
In Square D I-Line nomenclature, the "4" suffix indicates the breaker connects to the B and C phases of the panelboard bus.
Can I install this 2-pole breaker in a 3-phase I-Line panelboard?
Yes. The HDA260454 is designed to plug into a 3-phase I-Line bus stack, but it will only draw power from the B and C phases.
Can the HDA260454 be reverse fed?
No. I-Line plug-in circuit breakers cannot be reverse fed because the line side must connect directly to the panelboard bus stack.
How does the I-Line mounting system work for this breaker?
The breaker features plug-in jaws on the line side that ratchet firmly onto the I-Line bus stack using a retaining screw. The load side uses standard mechanical lugs for wire connections.
What type of enclosures or panels accept the HDA260454?
This breaker is compatible with Square D I-Line panelboards and switchboards. It is not compatible with standard unit-mount, QO, or NQ panelboards.
Does this breaker require a separate mounting bracket or hardware kit?
No. The I-Line mounting bracket and plug-in jaw connectors are factory-installed on the breaker. You only need a screwdriver to secure it to the panelboard bus stack.
Can I field-install a different trip unit in the HDA260454?
No. PowerPacT H-frame breakers with thermal-magnetic trip units have factory-sealed trip units that are not field-interchangeable.
