Product FAQs
6 answersWhat does the 'SA' suffix mean in the HGL36040SA catalog number?
The 'SA' suffix indicates that this circuit breaker includes a factory-installed 120V AC shunt trip. This allows the breaker to be tripped remotely using a 120V control signal, which is commonly used for emergency shutdown or industrial automation systems.
Can the Square D HGL36040SA be reverse fed?
Yes. Standard unit-mount PowerPacT H-frame thermal-magnetic circuit breakers with factory-sealed trip units are suitable for reverse connection (backfeeding).
What type of mounting does the HGL36040SA require?
The 'L' in the HGL prefix indicates this is a unit-mount circuit breaker. It is designed to be bolted directly to a backpan or mounting plate in a control panel or switchboard, and it connects via lugs on both the line and load sides.
What type of trip unit is installed in the HGL36040SA?
This breaker features a thermal-magnetic trip unit. It provides fixed long-time (thermal) protection for overloads and fixed instantaneous (magnetic) protection for short circuits.
Is the HGL36040SA compatible with Square D I-Line panelboards?
No. The HGL36040SA is a unit-mount breaker designed for lug-to-lug connections. For I-Line panelboards, you must use an I-Line plug-on breaker.
How does the HGL36040SA indicate a tripped condition?
When the breaker trips due to an overcurrent, short circuit, or a signal from the shunt trip, the handle moves to a distinct center position. This provides clear visual confirmation that the circuit has opened.
