Description
The LA3225PR is a 3-pole, 225A Eaton Tri-Pac MCCB. It combines thermal-magnetic trip functions with built-in current-limiting fuses to manage extreme faults. This unit bolts into Westinghouse PRL4 panelboards and motor control centers, serving as a replacement for legacy Cutler-Hammer installations. Featuring an interchangeable trip unit and a 200 kAIC rating at 600VAC, it restricts let-through energy to protect sensitive downstream equipment.Specifications

Product FAQs
7 answersWhat does the "PR" suffix indicate on the LA3225PR breaker?
The "PR" suffix designates this as a Tri-Pac current-limiting breaker. It includes integrally mounted fuses that work alongside the thermal-magnetic trip unit to safely interrupt extreme faults up to 200kA at 600VAC.
Which panelboards accept the LA3225PR circuit breaker?
This bolt-on breaker is designed for installation in legacy Westinghouse PRL4 panelboards, as well as compatible switchboards and motor control centers.
What is the magnetic trip adjustment range for this 225A breaker?
The adjustable magnetic trip unit can be set between 1125A and 2250A, allowing electricians to coordinate the instantaneous short-circuit response with downstream equipment.
What wire sizes do the standard lugs on the LA3225PR accept?
The standard pressure line and load terminals are rated for aluminum or copper conductors ranging from 4 AWG to 350 kcmil.
Does this breaker require external fuses to achieve its maximum interrupting rating?
No. The LA3225PR is a fused current-limiting breaker with built-in limiters. These integral fuses provide the 200kA at 600VAC interrupting capacity without the need for separate upstream fuse blocks.
Can the LA3225PR replace a standard LA3225 breaker?
The LA3225PR offers a significantly higher interrupting rating due to its integral Tri-Pac fuses. While both belong to the LA frame family, the fused version requires additional physical clearance. You must verify that your enclosure can accommodate the extended Tri-Pac housing before substituting.
What happens if the internal fuses in the LA3225PR blow during a fault?
The Tri-Pac fuse pack is mechanically interlocked with the breaker tripping mechanism. If the internal current-limiting fuses blow during an extreme fault, the breaker handle will trip and cannot be reset until the blown fuses are replaced and the fuse pack is properly bolted down.
