Description
Belonging to the legacy L-frame family, this 200A molded case circuit breaker provides essential long-time and instantaneous (LI) trip functions. It serves commercial and industrial facilities requiring robust power distribution. The unit mounts into Square D I-Line panelboards and switchboards. For modern upgrades, it is replaced by the PowerPact JJA36200, which requires a 1.5-inch HNM1BL blank filler plate due to its smaller footprint.Specifications

Product FAQs
7 answersWhat is the magnetic trip adjustment range for the LH36200?
The LH36200 features an adjustable magnetic trip range of 1000A (Low) to 2000A (High). The thermal trip is fixed at 200A.
What is the modern replacement for the legacy LH36200 circuit breaker?
The LH36200 is part of the legacy Square D L-frame family. For modern upgrades, it is typically replaced by a 200A PowerPact J-frame breaker, such as the JJA36200. Because the J-frame has a smaller footprint, installing it in an I-Line panel requires a 1.5-inch HNM1BL blank filler plate.
Can I install the LH36200 in a standard Square D QO or NQ panelboard?
No, the LH36200 features an I-Line plug-on connection. It is only compatible with Square D I-Line panelboards and switchboards designed to accept L-frame breakers.
How does the LH36200 connect to the panelboard bus?
The LH36200 utilizes Square D's I-Line plug-on mounting system. The line side features plug-on jaws that connect directly to the I-Line bus, while the load side uses traditional mechanical lugs.
What does the "H" in the LH36200 catalog number signify?
The "H" indicates that this is a high-interrupting circuit breaker within the legacy L-frame family. It provides higher fault current protection (such as 35kA at 480VAC) compared to standard LA-frame breakers.
Does the LH36200 include a push-to-trip feature?
Yes, it is equipped with a push-to-trip button. This allows electricians to manually trip the breaker to verify the mechanical operation of the trip mechanism without exposing themselves to live electrical parts.
Is the LH36200 suitable for HVAC applications?
Yes, the LH36200 is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment branch circuits.
