Description
Engineered for the legacy Mark 75 series, the HLA3225 provides 225A of reliable overcurrent protection for older Westinghouse and Cutler-Hammer systems. It mounts into existing switchboards and panelboards, offering a straightforward maintenance solution for facilities avoiding full system upgrades. Delivering 75 kAIC at 240VAC and 35 kAIC at 480VAC, the breaker employs thermal-magnetic trip technology with adjustable magnetic settings. It crosses over to the newer HLD3225 when upgrading.Specifications

Product FAQs
5 answersWhat panelboards are compatible with the HLA3225 circuit breaker?
This breaker is designed for use in legacy Westinghouse panelboards, Eaton Pow-R-Line C panelboards, and compatible switchboards.
What does the Mark 75 designation mean on this breaker?
The Mark 75 family designation indicates that the circuit breaker has a high interrupting capacity of 75,000 amperes (75 kAIC) at 240VAC.
What is the difference between the LA3225 and the HLA3225?
The HLA3225 is the high-interrupting version of the standard LA3225. While both are 225A, 3-pole L-Frame breakers, the HLA model provides higher short-circuit interrupting ratings.
How does the trip unit function on this L-Frame breaker?
It features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing you to set the instantaneous short-circuit pickup.
What wire sizes are accepted by the standard lugs on the HLA3225?
The standard bolt-on lugs accept aluminum or copper conductors ranging from 6 AWG to 350 kcmil.
