Description
Part of Eaton's Mark 75 series, the HKA3225 is a 3-pole, 225A molded case circuit breaker designed for commercial and industrial applications. It provides reliable thermal-magnetic protection with an interchangeable trip unit for flexible system design. This K-frame breaker installs into Westinghouse and Eaton Pow-R-Line C panelboards, switchboards, and motor control centers. Rated for 65kAIC at 240VAC and 35kAIC at 480VAC, it serves as a direct predecessor to the modern KD3225 and HKD3225.Specifications

Product FAQs
7 answersWhich panelboards and enclosures are compatible with the HKA3225?
This K-Frame breaker is designed for installation in legacy Westinghouse panelboards, Eaton Pow-R-Line C panelboards, switchboards, and motor control centers.
Does the HKA3225 include lugs for wire termination?
As a bolt-on breaker, the line side bolts directly to the panelboard bus. The load side includes standard mechanical lugs that accommodate 4 AWG to 350 kcmil copper or aluminum (Cu/Al) conductors.
What does the H in the HKA3225 part number indicate?
The H designates this as the high-interrupting capacity version of the standard KA frame. It provides elevated fault protection, including a 35kA interrupting rating at 480VAC and 65kA at 240VAC.
How is the trip unit configured on this breaker?
The HKA3225 features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic response can be adjusted via a dial on the front of the trip unit.
Can the Eaton HKA3225 replace older Westinghouse HKA breakers?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse molded case circuit breaker lines. The Eaton HKA3225 is a direct replacement for legacy Westinghouse and Cutler-Hammer breakers sharing the same catalog number.
Is the HKA3225 rated for direct current applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 22kA.
What are the modern equivalents to the HKA3225?
The HKA3225 is a direct predecessor to the modern Eaton Series C KD3225 and HKD3225 circuit breakers. When retrofitting, verify that your specific panelboard or enclosure accepts the newer Series C frames before substituting.
