The JD3250 – EATON 3P 250A 600V Molded Case Breaker is designed for reliable overcurrent protection in industrial applications. This robust circuit breaker features three poles and is rated for 250 amps and 600 volts, ensuring optimal performance and durability. Ideal for heavy-duty usage, it guarantees safety and efficiency in your electrical systems.
The JD3250 carries an 18 kA interrupting rating at 600 V. It is designed for commercial and industrial panelboards and switchboards — not residential loadcentres. You'll want to verify that your available fault current (AFC) at the installation point does not exceed 18 kA. If you need a higher interrupting rating for the same JD frame, Eaton offers higher-rated variants; contact us and we can help you identify the right option.
The JD-frame series has seen limited availability through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the JD3250 is no longer a standard stocked item, we can often source new, reconditioned, or equivalent units. Reach out to our Calgary, Edmonton, or Vancouver counter for availability and lead time.
A direct replacement must match on frame size (JD), pole count (3P), ampere rating (250 A), voltage rating (600 V), and interrupting rating (18 kA minimum), as well as the panelboard's bolt-on bus provisions. Substituting a different frame or brand requires verifying that the replacement is listed and approved for that enclosure. Send us your existing breaker part number and panelboard model and we'll confirm a compatible replacement.
