Product FAQs
9 answersWhat panelboards and enclosures are compatible with the LDC3500?
This breaker is designed for use in Eaton Pow-R-Line 4 panelboards, as well as compatible switchboards and motor control centers.
What wire sizes are accepted by the standard lugs on the LDC3500?
The standard lugs accept two 3/0 AWG to 350 kcmil aluminum or copper wires per phase.
What is the difference between the LD, HLD, and LDC frame breakers?
In the Eaton Series C L-Frame family, these prefixes indicate the interrupting capacity. The standard LD frame is rated 35 kAIC at 480 VAC, the HLD is rated 65 kAIC, and the LDC provides the highest rating at 100 kAIC at 480 VAC.
Can I use this Eaton LDC3500 to replace an older Cutler-Hammer or Westinghouse LDC3500?
Yes. Eaton acquired Cutler-Hammer and Westinghouse distribution equipment. The Series C LDC3500 shares the exact same physical footprint and electrical ratings across all three brand names.
Is the trip unit on the LDC3500 interchangeable?
Yes, the LDC3500 features an interchangeable trip unit. This allows you to swap the thermal magnetic trip unit for a different rating or an electronic trip unit without replacing the entire breaker frame.
Is the LDC3500 rated for direct current applications?
Yes, this breaker is rated for up to 250 VDC with an interrupting capacity of 22 kAIC, making it suitable for specific DC distribution systems.
How is the magnetic trip adjusted on this breaker?
The LDC3500 has a fixed thermal and adjustable magnetic trip unit. You can adjust the instantaneous magnetic trip setting using the dial on the front of the trip unit to coordinate with downstream devices.
What are the physical dimensions of the LDC3500 L-Frame breaker?
The LDC3500 measures 8.25 inches high, 8.25 inches wide, and 8.25 inches deep.
What does the LI trip function code mean on the LDC3500?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short circuit protection.
