The KD3300 is a robust Eaton 3-Pole Moulded Case Circuit Breaker rated at 300A and 600V, designed for reliable overload and short-circuit protection. Ideal for commercial and industrial applications, this breaker ensures optimal performance and safety. Its durable construction and compact design make it a perfect fit for diverse electrical systems.
The KD3300 is a KD-frame bolt-on MCCB designed for Eaton commercial and industrial panelboards and switchboards that accept KD-frame devices. It is not compatible with residential loadcentres. Because compatibility depends on your specific enclosure and bus rating, we recommend sending us your panelboard model number so we can confirm before you order.
The Eaton KD-frame series has been subject to product line changes over the years, and availability can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the KD3300 is discontinued or on long lead time through standard channels, we can often source it. Contact our Calgary, Edmonton, or Vancouver counter for current stock status.
The KD3300 can serve as either a feeder breaker or a main disconnect breaker, provided the panelboard or switchboard it is installed in is rated and configured for a main breaker of this frame and ampacity. Always verify with your electrical engineer or authority having jurisdiction (AHJ) that the installation meets CEC (Canadian Electrical Code) requirements for your specific application.
