Product FAQs
7 answersIs the Eaton NDC312T32W circuit breaker 80% or 100% rated?
The NDC312T32W is a standard 80% rated circuit breaker. For applications requiring a 100% continuous current rating, the CNDC312T32W is the equivalent model.
Can the Digitrip 310 electronic trip unit be replaced in the field?
No. In Eaton Series C N-frame circuit breakers, the trip unit is built in as an integral part of the breaker and is not field replaceable.
Does the NDC312T32W require a rating plug to operate?
Yes. This breaker requires the installation of a rating plug to establish the maximum continuous current rating and make the Digitrip 310 trip unit operational.
What adjustability does the LSI trip function provide on this breaker?
The Digitrip 310 LSI trip unit allows you to adjust the Long-Time, Short-Time, and Instantaneous pickup and delay settings to precisely coordinate with other circuit protection devices in your system.
Does the NDC312T32W include ground fault protection?
No, this specific model features an LSI trip unit (Long-Time, Short-Time, Instantaneous). If ground fault protection is required, you will need a model with an LSIG trip unit.
What type of wire can be used with the lugs on this N-frame breaker?
When equipped with standard Eaton AL9CU terminal lugs, you can use either copper or aluminum conductors. Always use 90 degree Celsius rated wire sized according to 75 degree Celsius ampacity guidelines.
Can the NDC312T32W be used in DC voltage applications?
No. The Digitrip 310 electronic trip unit is designed for AC applications only and is not suitable for DC systems.
