The EATON KD3350 is a robust 3-pole moulded case breaker designed for reliable circuit protection. With a current rating of 350A and a voltage capacity of 600V, it ensures safe operation in demanding environments. Ideal for industrial applications, this breaker offers superior performance and a durable design. Perfect for your power management needs.
The KD3350 carries an 18 kA interrupting rating at 600V AC. This is suitable for many commercial and industrial distribution applications, but you should verify that your available fault current (AFC) at the installation point does not exceed 18 kA. If your system has higher fault levels, a higher-interrupting-rated KD-frame variant may be required — contact us and we can help identify the right option.
The KD frame is a legacy Eaton/Cutler-Hammer series, and availability of new units can be limited through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain access to surplus new, reconditioned, and tested stock. Contact our Calgary, Edmonton, or Vancouver counter for current availability and lead times.
The Eaton KD frame supports a range of accessories including shunt trips, auxiliary contacts, and alarm switches, depending on the specific breaker configuration. However, not all accessories are compatible with every variant of the KD3350. We recommend confirming your accessory requirements with us so we can verify fitment and source the correct parts alongside the breaker.
