Product FAQs
6 answersWhat phase connection does the HDA260401 circuit breaker use?
The 1 at the end of the HDA260401 catalog number indicates it is configured for an AB phase connection on the I-Line bus.
What is the direct replacement for the legacy FA26040 breaker?
The HDA260401 PowerPacT H-frame breaker is the direct replacement for the obsolete FA26040 2-pole I-Line circuit breaker.
What tool is required to tighten the load-side lugs on the HDA260401?
The standard AL150HD lugs on this H-frame breaker require a 3/16-inch hex bit for proper torque application during installation.
How does the I-Line connection handle high-level short circuits?
The I-Line plug-on jaws utilize a blow-on design. During high-level short circuit conditions, magnetic forces draw the connector jaws together, gripping the bus bar more firmly to maintain a secure connection.
Can the HDA260401 be used in DC voltage systems?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 20 kA interrupting capacity, making it suitable for both AC and DC applications.
Is the trip unit on the HDA260401 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit with long-time and instantaneous (LI) protection functions.
