Product FAQs
8 answersDoes the Eaton DK3350W come with line and load lugs?
No. The W suffix in the DK3350W catalog number indicates that it is supplied without line and load terminals. Lugs or terminal kits must be sourced separately based on your specific wire size and application requirements.
What frame size is the DK3350W circuit breaker?
The DK3350W is an Eaton Series C K-frame molded case circuit breaker. It shares the standard K-frame footprint, making it compatible with existing enclosures and hardware designed for this specific frame size.
Is the trip unit on the DK3350W adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials for trip settings.
What types of equipment can the DK3350W be installed in?
This unit mount circuit breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
Can the DK3350W be reverse fed?
Yes. Eaton Series C K-frame circuit breakers with non-interchangeable thermal-magnetic trip units, such as the DK3350W, are suitable for reverse feed applications.
Can I use the DK3350W to replace an older Cutler-Hammer DK3350?
Yes, the DK3350W is the direct equivalent to the DK3350, with the W simply designating that it ships without lugs. You can reuse your existing lugs if they are in good condition and torqued to the manufacturer specifications.
Is the DK3350W rated for 480V or 600V systems?
No. The DK frame is strictly rated for a maximum of 240V AC or 250V DC. If your application requires 480V or 600V, you will need a KD or HKD frame breaker instead.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker provides Long-Time (thermal) and Instantaneous (magnetic) trip functions. This is the standard protection profile for general power distribution and feeder circuits.
