Product FAQs
5 answersWhat is the difference between Eaton KD, HKD, and KDC circuit breakers?
The primary difference is their short-circuit interrupting rating. While they share the exact same physical K-frame dimensions, at 240VAC the KD is rated for 65kAIC, the HKD for 100kAIC, and the KDC for 200kAIC.
Can I use the KDC3250 to upgrade a KD3250 or HKD3250 breaker?
Yes. Because the KDC3250 shares the same physical footprint and mounting configuration as the KD3250 and HKD3250, it serves as a direct drop-in replacement for systems requiring higher fault current protection.
Is the KDC3250 suitable for reverse feed applications?
Yes, this breaker is rated for reverse feed installations. This allows electricians to supply power to either the top or bottom terminals, providing flexibility for specific enclosure layouts.
How does the adjustable magnetic trip on the KDC3250 work?
The breaker features a fixed thermal element for standard overload protection and an adjustable magnetic element for short circuits. The adjustable magnetic trip allows you to tune the instantaneous response threshold, which helps prevent nuisance tripping from high inrush currents like motor startups.
Does the KDC3250 provide ground fault protection?
No, the KDC3250 is equipped with an LI (Long-Time, Instantaneous) thermal-magnetic trip unit. This provides standard overload and short-circuit protection but does not include built-in equipment ground fault protection.
