Product FAQs
6 answersWhich legacy Square D breakers does the HGA260151 replace?
The HGA260151 PowerPacT H-frame breaker is the direct drop-in replacement for discontinued F-frame models, specifically the FA26015AB and FH26015AB. It provides an exact physical match for older Square D I-Line panelboards.
What does the 1 suffix in the HGA260151 part number indicate?
The 1 suffix indicates a factory-configured AB phase connection. This two-pole breaker is specifically designed to connect to the A and B phases on the bus stack of a Square D I-Line panelboard.
How does this breaker mount into an I-Line panelboard?
The breaker features an I-Line plug-on design with blow-on type jaw connections. Under high fault currents, magnetic forces draw the jaws tighter against the bus bar for a more secure grip. It ratchets firmly onto the bus stack using a screwdriver and is secured with a mounting screw, eliminating the need for separate bus cabling.
What type of fault protection does the thermal-magnetic trip unit provide?
The integrated thermal-magnetic mechanism delivers dual-function protection. The thermal component provides long-time delayed tripping for sustained overloads, while the magnetic component offers instantaneous tripping to quickly clear severe short circuits.
Can I use aluminum wire with the HGA260151 load lugs?
Yes, the factory-installed load lugs are dual-rated for both aluminum and copper conductors. They accept wire sizes from 14 AWG up to 3/0 AWG. It is recommended to apply a listed oxide inhibitor when terminating aluminum wire to prevent oxidation.
Does the HGA260151 include a push-to-trip feature?
Yes, it includes a push-to-trip button on the faceplate. This allows electricians to manually trip the breaker mechanism to verify proper mechanical operation and safely test any installed auxiliary devices.
