Product FAQs
7 answersWhat type of panelboards are compatible with the BJA260604 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes a plug-in jaw connection that mounts directly onto the I-Line bus structure.
What phase connection does the BJA260604 use?
The 4 at the end of the BJA260604 catalog number indicates it is configured for a BC phase connection on the I-Line bus.
Which legacy Square D breakers does the BJA260604 replace?
The PowerPacT B-frame is the modern replacement for legacy F-frame breakers, specifically the FH26060BC. It can also serve as a substitute for the H-frame HJA260604, as they share the same 60A rating, BC phase connection, and I-Line mounting.
What do the letters BJA stand for in this breaker's catalog number?
The letter B designates the PowerPacT B-frame family. The J indicates the interrupting rating class, which provides 65 kAIC at 480VAC. The A specifies that the breaker has an I-Line plug-in mounting configuration.
How does the BJA260604 mount into the panel?
It features an I-Line style plug-in connection. The breaker uses a jaw-type mechanism that clamps directly onto the panel's busbars, allowing for quick, tool-free bus connection before securing the retaining bracket.
Does the BJA260604 include a manual trip testing feature?
Yes, like all PowerPacT circuit breakers, it features an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism.
Can I run a continuous 60A load on the BJA260604?
Standard PowerPacT B-frame breakers are rated for 80 percent continuous load. Per the NEC, continuous loads lasting 3 hours or more should not exceed 80 percent of the breaker's 60A rating, which is 48 amps.
