Description
Operating within industrial power systems, the Square D KAL36125 is a 3-pole, 125A molded case circuit breaker from the legacy K-Frame series. It features thermal-magnetic trip technology with an adjustable magnetic response. This unit-mount breaker fits into Square D switchboards, enclosures, and motor control centers. As a legacy component, it is functionally replaced by the modern PowerPact H-Frame series (like the HGL36125). It delivers 42kAIC at 240VAC and is HACR rated for HVAC use.Specifications

Product FAQs
8 answersWhat are the magnetic trip settings for the Square D KAL36125?
The KAL36125 features an adjustable magnetic trip with a low setting of 625 amps and a high setting of 1250 amps. The continuous thermal trip is fixed at 125 amps.
What is the difference between Square D KAL and KHL frame circuit breakers?
Both are K-frame breakers with identical physical dimensions and unit mounting, but they have different short-circuit interrupting ratings. The standard KAL series is rated for 25 kA at 480V, while the KHL high-interrupting series is rated for 35 kA at 480V.
What is the modern replacement for the obsolete KAL36125?
The Square D K-frame series is a legacy product. For new installations or functional replacements, Schneider Electric recommends the PowerPact H-frame series, such as the HGL36125. Upgrading to a PowerPact breaker may require different mounting hardware or enclosure modifications.
What size wire is compatible with the standard lugs on the KAL36125?
The factory-installed AL250KA lug kit supplied with this breaker accepts one 4 AWG to 350 kcmil aluminum or copper conductor per pole.
What is the wire tightening torque for the AL250KA lugs on this breaker?
The standard AL250KA mechanical lugs require a wire binding screw torque of 250 lb-in (28 N-m) for 4 AWG to 350 kcmil conductors. Always refer to the physical label on the breaker to confirm terminal torque specifications before energizing.
Can the KAL36125 be installed in a Square D I-Line panelboard?
No. The KAL36125 is a unit-mount circuit breaker meant for standard enclosures, switchboards, and motor control centers. For an I-Line panelboard, you must use a plug-on breaker such as the Square D KA36125.
Can the KAL36125 be reverse-fed for use as a main breaker?
Yes. Square D KAL thermal magnetic circuit breakers do not have marked line and load sides by default, meaning they can be reverse-fed. Be sure to follow all local code requirements for backfed breaker hold-down kits and panel labeling.
Is this circuit breaker rated for HACR applications?
Yes, the KAL36125 is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration motor loads.
