Designed to protect electrical systems from overloads and short circuits, this durable breaker combines advanced technology with robust construction.

The KDC3350 is a KD-frame MCCB designed for Eaton/Cutler-Hammer industrial-grade panelboards and switchboards that accept KD-frame bolt-on breakers. It is not suitable for residential loadcentres such as BR or CH panels. Send us your panelboard or switchboard model number and we'll confirm whether the KDC3350 is the right fit.
Availability can vary as Eaton periodically updates or supersedes MCCB frame series. Northern Breaker Group specializes in sourcing obsolete and hard-to-find breakers across Canada. Whether the KDC3350 is a current or discontinued part, contact our Calgary, Edmonton, or Vancouver team and we'll work to locate the unit or confirm a compatible replacement.
The KDC3350's 350A, 600V, 65kA rating makes it suitable for use as either a feeder breaker or a main disconnect breaker in commercial and industrial distribution equipment, depending on your panel or switchboard configuration and local electrical code requirements. We recommend confirming the intended application with your engineer or inspector, and our team can help identify the right accessories (such as lugs or mounting hardware) for your installation.
