Description
Engineered for demanding industrial environments, the Eaton LA3200PR is a 3-pole, 200A current-limiting circuit breaker equipped with Tri-Pac fused technology. It provides reliable thermal-magnetic protection with fixed thermal and adjustable magnetic trip settings. Designed as a bolt-on solution, it fits seamlessly into Westinghouse PRL4 panelboards and motor control centers. With a massive 200 kAIC interrupting rating at 600VAC, it effectively minimizes let-through current.Specifications

Product FAQs
6 answersWhich panelboards and enclosures accept the LA3200PR circuit breaker?
This L-frame breaker is designed for use in legacy Westinghouse and Cutler-Hammer PRL4 panelboards, as well as compatible switchboards and motor control centers. It requires the appropriate bolt-on mounting hardware specific to the enclosure type.
How does the LA3200PR achieve its 200kA interrupting rating at 600 VAC?
This model features an integrally fused, current limiting design. The built-in current limiters allow the breaker to safely interrupt extremely high fault currents up to 200kA across all AC voltage levels (240V, 480V, and 600V) without sustaining damage.
How is the magnetic trip function configured on this breaker?
The LA3200PR features a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection. The instantaneous magnetic trip can be adjusted between 1000 and 2000 amps to accommodate different motor inrush currents or coordination requirements.
What type of wire connections are provided on the LA3200PR?
The breaker comes equipped with standard pressure line and load terminals (lugs) that accept both aluminum and copper conductors. The lugs are rated for wire sizes ranging from 4 AWG up to 350 kcmil.
Can I use this Eaton LA3200PR to replace an older Westinghouse or Cutler-Hammer breaker with the exact same part number?
Yes. Eaton acquired the Westinghouse distribution equipment line and integrated it into their Cutler-Hammer brand. An Eaton, Cutler-Hammer, or Westinghouse LA3200PR are physically and electrically identical and can be used as direct replacements for one another.
What are the physical space requirements for installing this breaker?
The breaker measures 8.25 inches wide, 4.75 inches deep, and 16 inches high. Ensure your PRL4 panelboard or switchboard chassis has adequate space and the correct L-frame mounting brackets before installation.
