Product FAQs
7 answersWhat does the YP suffix mean on the HJA36100YP?
The YP suffix indicates that this circuit breaker includes a factory-installed handle padlock attachment. This allows the breaker to be locked in the ON or OFF position for safety and maintenance procedures.
What type of panelboard is the HJA36100YP designed for?
This breaker features an I-Line style plug-in connection, making it compatible exclusively with Square D I-Line panelboards and switchboards. It cannot be installed in standard load centers or unit-mount enclosures.
Can the HJA36100YP replace older Square D I-Line breakers?
Yes, the PowerPacT H-frame I-Line breakers are the direct, designated replacements for legacy Square D F-frame I-Line breakers, such as the FA, FH, and FC series, of the same amperage and pole configuration.
Does this breaker require a separate mounting bracket for installation?
No, the HJA36100YP features an I-Line plug-in design with integrated phase sequence jaws that seat directly onto the panelboard bus. This eliminates the need for separate mounting hardware or bus connections on the line side.
What type of protection does the HJA36100YP provide?
This breaker features a thermal-magnetic trip unit that provides both long-time thermal protection against overloads and instantaneous magnetic protection against short circuits. Both the thermal and magnetic trip points are fixed.
What is the maximum frame capacity of the PowerPacT H-frame series?
The PowerPacT H-frame is a 150A maximum frame circuit breaker. The HJA36100YP utilizes this frame size but is factory configured with a 100A continuous current rating.
Does the HJA36100YP require a specific phase connection?
Yes, this I-Line breaker is designed with an ABC phase sequence. The plug-on jaws are configured to seat directly onto the A, B, and C phases of the panelboard bus.
