Description
A drop-in replacement for older Westinghouse systems, the HK3200 is a 200A, 3-pole molded case circuit breaker. It is engineered for commercial and industrial power distribution. This K-Frame MCCB installs into legacy panelboards, switchboards, and motor control centers without requiring custom adapters. It is officially replaced by the modern HKD3200. Featuring thermal-magnetic trip technology with adjustable magnetic settings, it delivers a 65 kAIC interrupting capacity at 480VAC.Specifications

Product FAQs
6 answersIs the HK3200 interchangeable with other Eaton Series C K-frame breakers?
Yes, the HK3200 shares the same physical footprint as KD, KDB, and HKD frame breakers. It installs into legacy Westinghouse panelboards and switchboards without requiring custom adapters. It is officially replaced by the modern HKD3200.
What enclosures and systems are compatible with the HK3200?
This K-frame breaker is designed for use in Westinghouse and Eaton Cutler-Hammer panelboards, switchboards, and motor control centers that accept Series C K-frame breakers.
How does the adjustable magnetic trip function on the HK3200?
The thermal magnetic trip unit features a fixed thermal element for overload protection and an adjustable magnetic setting. This allows users to dial in the instantaneous short circuit pickup level for better coordination with downstream devices.
What does the LI trip function code indicate on this breaker?
The LI designation means the breaker provides Long Time (L) and Instantaneous (I) protection. The Long Time function protects against sustained overloads, while the Instantaneous function provides immediate tripping during severe short circuits.
Are the standard lugs on the HK3200 rated for both aluminum and copper wire?
Yes, the factory-installed line and load lugs are dual-rated for both aluminum and copper conductors ranging from 3 AWG to 350 kcmil. Use an appropriate oxide inhibitor when terminating aluminum wire.
What is the advantage of the high interrupting capacity on the HK3200?
With a 65 kAIC rating at 480VAC, this breaker safely clears severe fault currents in commercial and industrial systems with high available fault current. This prevents catastrophic equipment damage and helps maintain system stability during short circuit events.
