Product FAQs
8 answersWhat panelboards are compatible with the HLA260301 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a plug-on line-side connection that mounts directly to the I-Line bus assembly.
What is the recommended lug torque for the load-side terminals on this 30A H-Frame breaker?
For the standard mechanical lugs accepting 14 to 3/0 AWG aluminum or copper wire, the recommended tightening torque is 44.3 lb-in (5 N.m). Always verify against the label on the breaker prior to installation.
How does the I-Line connection work on the HLA260301?
The breaker uses blow-on type line-side connectors that plug directly onto the panelboard bus bars. During a short circuit, increased magnetic flux causes the jaws to tighten their grip on the bus, ensuring a secure electrical connection under fault conditions.
Can the HLA260301 be used in DC electrical systems?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, providing an interrupting capacity of 20kA at that voltage.
Is the HLA260301 rated for 80 percent or 100 percent continuous current?
Standard PowerPacT H-Frame thermal-magnetic breakers like the HLA260301 are rated for 80 percent continuous current. Breakers with a 100 percent rating require a specific catalog number suffix.
Does this breaker include a push-to-trip feature?
Yes, all PowerPacT H-Frame circuit breakers feature 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 trip mechanism.
Is the HLA260301 suitable for isolation?
Yes, PowerPacT H-Frame circuit breakers are suitable for isolation as defined in the IEC 60947-2 standard. The operating handle will only indicate the OFF position if the contacts are physically open.
Can the trip unit on the HLA260301 be swapped for an electronic Micrologic unit?
No, the HLA260301 comes with a factory-sealed, fixed thermal-magnetic trip unit. The trip unit is non-interchangeable. If you require electronic trip functions, you must select a different PowerPacT H-Frame breaker configured with a Micrologic trip unit.
