The Eaton KDC3250 is a KDC-frame moulded case circuit breaker (MCCB) rated 250A, 3-pole, 600V AC, 65kA interrupting capacity. As an industrial/commercial MCCB, it is designed for installation in panelboards, switchboards, and motor control centres that accept KDC-frame bolt-on breakers — not residential loadcentres. It is well-suited to protecting feeders, sub-panels, and large motor branch circuits in commercial and industrial facilities across Canada.
Compatibility depends on your specific enclosure or switchboard bus configuration. Send us your panelboard or switchboard model and we'll confirm fit.
Yes — the KDC3250 carries a 65kA interrupting rating at 600V, making it well-suited for commercial and industrial distribution systems where high available fault current is a concern. Always verify the available fault current at the installation point matches or is below this rating, as required by the Canadian Electrical Code (CEC).
The KDC3250 is a general-purpose MCCB suitable for both feeder protection and branch-circuit protection in commercial and industrial applications. For motor protection specifically, ensure the breaker's trip characteristics and sizing comply with CEC Section 28 requirements for the motor load in question.
