Product FAQs
6 answersWhat panels and enclosures are compatible with the Eaton EDS3150?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It mounts using a standard bolt-on configuration.
Can the EDS3150 replace older Westinghouse F-frame breakers?
Yes, Eaton Series C F-frame breakers are physically interchangeable with older Westinghouse F-frames, including FD, FDB, and HFD models. You must verify that the 150A rating and 42kAIC at 240VAC meet or exceed your system requirements before replacing an older unit.
What type of protection does the LI trip function provide on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. This is a standard thermal magnetic configuration where the thermal element protects against prolonged overloads (Long-Time) and the magnetic element trips immediately during a short circuit (Instantaneous).
Is the EDS3150 suitable for direct current (DC) applications?
Yes, in addition to its 240VAC rating, this breaker is rated for 125VDC systems. When used in DC applications, it provides an interrupting capacity of 10kAIC.
What wire sizes are accepted by the standard lugs on the EDS3150?
The factory-installed lugs accept copper or aluminum conductors ranging from 4 AWG to 4/0 AWG. Ensure you torque the terminals to the manufacturer specifications printed on the breaker label during installation.
How does the EDS series differ from other Eaton Series C F-frame breakers like the FD or HFD?
The EDS series is specifically rated for a maximum of 240VAC with a 42kAIC interrupting capacity. Other F-frame models like the FD or HFD may have different maximum voltage ratings (up to 600VAC) or different interrupting capacities, even though they share the exact same physical dimensions.
