Product FAQs
9 answersWhat does the "SA" suffix in the HGA36125SA catalog number indicate?
The "SA" suffix means this circuit breaker is equipped with a factory-installed 110-130 VAC shunt trip. This allows the breaker to be tripped remotely by applying a voltage signal to the shunt trip coil.
What is the interrupting rating of the HGA36125SA at 600VAC?
This H-frame breaker has an interrupting capacity of 18kAIC at 600VAC.
What type of panelboard is the HGA36125SA compatible with?
This breaker features an I-Line style plug-on connection, making it compatible with Square D I-Line panelboards and switchboards. It uses a plug-on connection for the line side and mechanical lugs for the load side.
Is the HGA36125SA rated for 80% or 100% continuous current?
This breaker has a standard 80% continuous current rating.
Can the HGA36125SA replace an obsolete KA36125 circuit breaker?
Yes, the PowerPacT H-frame series is the direct functional replacement for the legacy K-frame KA36125. Both utilize the same I-Line plug-on mounting. Keep in mind that the HGA36125SA includes a factory-installed 110-130 VAC shunt trip, so ensure your application requires this feature before substituting.
What is the phase connection for this I-Line circuit breaker?
This 3-pole breaker features a standard ABC phase connection on the I-Line bus.
What are the magnetic hold and trip currents for the HGA36125SA?
The thermal-magnetic trip unit on this 125A breaker has a fixed magnetic hold current of 900A and a magnetic tripping current of 1700A.
What is the tightening torque for the load side lugs on the HGA36125SA?
The AL150HD mechanical lugs require a tightening torque of 50 in-lbs for 14-10 AWG wire, and 120 in-lbs for 8-3/0 AWG wire. Use a 3/16-inch hex wrench for installation.
What safety standards and certifications does the HGA36125SA meet?
This PowerPacT H-frame breaker is UL Listed, CSA Certified, NOM Certified, and CE marked. It also carries a HACR rating for use with heating, air conditioning, and refrigeration equipment.
