Product FAQs
7 answers
Does the Eaton LD3600T106W come with line and load lugs installed?
No, the "W" suffix in the catalog number indicates this breaker is supplied without terminals. You will need to purchase a compatible Series C L-frame lug kit separately, such as the 3TA603LDK or 3TA632LK, depending on your wire size requirements.
What does the LSIG trip function on the LD3600T106W allow me to adjust?
The electronic LSIG trip unit allows you to independently adjust the pickup and delay settings for long-time, short-time, instantaneous, and ground-fault protection. This provides precise selective coordination with other breakers in your electrical distribution system.
What types of equipment is the LD3600T106W circuit breaker compatible with?
This L-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It can also be installed in individual enclosures that accept 600A L-frame breakers.
Can I use the LD3600T106W to replace an older Cutler-Hammer L-frame breaker?
Yes, this breaker is part of the Eaton and Cutler-Hammer Series C family. It shares the same physical dimensions and mounting footprint as older Series C L-frame breakers, making it a direct replacement for equivalent 600A models.
Does the LD3600T106W provide equipment ground-fault protection?
Yes, the "G" in the LSIG trip unit designates ground-fault protection. This function is designed to protect equipment from damaging low-level faults to ground, which is often required by the National Electrical Code for specific applications.
How is the LD3600T106W mounted in a panel?
It is a unit-mount, bolt-on circuit breaker. It secures directly to the bus or mounting pan using bolts, rather than plugging into a busbar.
Does the LD3600T106W support system monitoring and communications?
Yes, this breaker is equipped with an OPTIM 1050 electronic trip unit. In addition to providing adjustable LSIG protection, the OPTIM 1050 can monitor power, energy, and power factor, and it supports two-way communication for remote monitoring and control.
