Operating as a robust 3-pole, 200A molded case circuit breaker, the KAL36200-1380 belongs to Square D's legacy K-Frame family. Designed for unit-mount applications, it fits seamlessly into Square D enclosures, switchboards, and motor control centers. This specific model is equipped with a factory-installed 120VAC shunt trip and a 1A/1B auxiliary switch, providing both remote tripping and status signaling capabilities. It delivers reliable long-time and instantaneous protection.
What does the -1380 suffix indicate on the KAL36200-1380?
The -1380 suffix designates a factory-installed 120VAC shunt trip accessory, allowing the breaker to be tripped remotely via a control signal.
What wire sizes do the standard lugs accept?
The line and load lugs accommodate 4 AWG to 350 kcmil aluminum or copper conductors.
What equipment is this unit-mount breaker designed for?
This feed-thru K-frame breaker is intended for legacy Square D switchboards, motor control centers, and standalone enclosures.
Are the trip settings adjustable on this model?
The thermal magnetic trip unit features a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection.
Can this unit-mount KAL breaker be installed in an I-Line panelboard?
No. The KAL series is designed for unit-mount, feed-thru applications. I-Line panelboards require plug-on breakers like the KIL or KCL series.
How does the shunt trip accessory function for safety applications?
The 120VAC shunt trip requires a dedicated control circuit. When voltage is applied to the accessory leads, it activates the trip mechanism to safely open the breaker contacts during an emergency or automated shutdown.
