Product FAQs
8 answersDoes the HND312T32W come with terminal lugs installed?
No, this breaker is supplied without terminals. You will need to purchase a compatible lug kit separately, such as the TA1200NB1, which accepts four 4/0 AWG to 500 kcmil cables per phase.
Is a rating plug required to operate this circuit breaker?
Yes, the Digitrip 310 electronic trip unit requires a rating plug to function correctly. For a full 1200A rating, a 12NES1200T rating plug is typically used.
What does the LSI designation mean on the trip unit?
LSI indicates that the electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous trip functions. This allows for precise coordination with other protective devices in your electrical system.
What types of equipment is the HND312T32W compatible with?
This N-Frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
Is the HND312T32W a 100 percent rated circuit breaker?
No, standard HND breakers like the HND312T32W are 80 percent rated. If your application requires a 100 percent rated breaker, you would need the CHND312T32W variant.
Can the trip unit on the HND312T32W be replaced in the field?
No, the trip unit is built in as an integral part of the N-Frame Series C circuit breaker and is not field replaceable.
