Product FAQs
6 answersWhat enclosures are compatible with the KDC3150 circuit breaker?
The KDC3150 is designed to mount in Eaton Series C panelboards, switchboards, and motor control centers. It uses a standard K-frame panel mount configuration.
What is the adjustable magnetic trip range for this 150A breaker?
The magnetic trip on the KDC3150 is adjustable from 5 to 10 times the continuous ampere rating. For this 150A model, the instantaneous trip range is 750A to 1500A.
What is the difference between the KD3150, HKD3150, and KDC3150?
These are all 150A, 3-pole Series C K-frame breakers, but they feature different interrupting capacities. The KD3150 is standard (35 kAIC at 480VAC), the HKD3150 is high-interrupting (65 kAIC at 480VAC), and the KDC3150 is ultra-high interrupting and current limiting (100 kAIC at 480VAC).
Which terminal lug kit is standard for the KDC3150?
The standard factory-installed lug kit for the 150A KDC3150 is the TA300K. These pressure-type terminals accept 3 AWG to 350 kcmil aluminum or copper conductors.
Is the KDC3150 rated for 100 percent continuous operation?
No, standard KDC thermal-magnetic breakers are rated for 80 percent continuous operation. Eaton requires the CKD or CHKD series with electronic trip units for 100 percent rated K-frame applications.
Does the KDC3150 include the trip unit and lugs, or are they sold separately?
The KDC3150 catalog number represents a complete, factory-assembled circuit breaker. It includes the KDC frame, the KT3150T thermal-magnetic trip unit, and standard line and load terminals.
