Product FAQs
8 answersWhat frame size is the Eaton HKDDC3400F?
This breaker belongs to the Eaton Series C K-frame family. It is designed to be installed in compatible Eaton panelboards, switchboards, and motor control centers.
How should the poles be wired for direct current applications?
For maximum DC voltage ratings, the poles of the HKDDC3400F must be wired in series. Consult Eaton instruction leaflets for specific wiring diagrams based on whether your system is grounded or ungrounded.
What types of applications is the HKDDC3400F engineered for?
While it supports AC voltages, this high-interrupting breaker is specifically engineered for heavy-duty direct current systems, including commercial solar arrays, photovoltaic (PV) systems, and data centers.
Are terminal lugs included with this circuit breaker?
No, the HKDDC3400F is supplied without terminal lugs. You will need to select and install the appropriate line and load lugs based on your specific conductor size and material.
What field-installable accessories are compatible with this breaker?
It accepts standard Eaton Series C K-frame internal accessories, including shunt trips, auxiliary switches, undervoltage releases, and alarm switches.
What safety precautions are required before inspecting this breaker?
Always verify that the circuit breaker is switched to the OFF position and that no voltage is present across the line or load terminals before performing any inspection or maintenance.
Can this breaker be used to replace older Westinghouse or Cutler-Hammer models?
Yes, Eaton Series C K-frame breakers are directly interchangeable with legacy Westinghouse and Cutler-Hammer Series C K-frame breakers of the same specifications.
Can the HKDDC3400F be reverse fed?
Yes, this Eaton Series C K-frame breaker is suitable for reverse-feed applications. However, special attention must be paid during installation and maintenance to ensure no voltage is present, as energized equipment can cause severe injury.
