Product FAQs
6 answersWhat does the "SA" suffix mean on the HGL36150U33XSA?
The "SA" suffix indicates that this circuit breaker comes with a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely for emergency disconnects, fire alarm integration, or automation control.
What does the "U33X" in the catalog number indicate?
The "U33X" designates the inclusion of a Micrologic 3.2S electronic trip unit. This provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) trip functions, offering more precise coordination than standard thermal-magnetic breakers.
Can I field-install a shunt trip on a standard H-Frame breaker instead of buying the SA version?
No. According to Square D specifications, shunt trips for these molded case circuit breakers are factory-installed and take up internal space. They are not field-installable, so you must order a breaker with the correct suffix, such as this SA model, if remote tripping is required.
What does the "G" in the HGL frame type represent?
The "G" designates the specific interrupting rating tier for this PowerPacT H-Frame breaker. If your application requires a higher short-circuit current rating, you would need to cross-reference to a "J" or "L" interrupting tier model, such as an HJL or HLL breaker.
What does the "L" in the HGL prefix signify?
The "L" indicates that this is a unit-mount circuit breaker equipped with lugs on both the line and load sides. It is designed for feed-thru connections, unlike "A" suffix models (such as HGA) which are built for I-Line panelboard mounting.
How do I manually test the tripping mechanism on this breaker?
All PowerPacT H-Frame circuit breakers feature an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the mechanical operation of the trip mechanism.
