Product FAQs
7 answersWhat enclosures or equipment are compatible with the HND312T35W?
This N-Frame circuit breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
What does the LSG designation mean on the HND312T35W trip unit?
The LSG designation indicates that the electronic Digitrip 310 trip unit provides Long-Time, Short-Time, and Ground-Fault protection. This allows for precise coordination and ground-fault monitoring in industrial power systems.
Does the HND312T35W require a rating plug to operate?
Yes, Eaton N-Frame circuit breakers with electronic trip units require a compatible rating plug to establish the maximum continuous current rating and make the breaker operational.
What is the difference between the ND312T35W, HND312T35W, and NDC312T35W?
The difference is the interrupting capacity at 480VAC. The standard ND312T35W is rated at 50kAIC, the high-interrupting HND312T35W is rated at 65kAIC, and the ultra-high NDC312T35W is rated at 100kAIC.
Is the HND312T35W rated for 100 percent continuous operation?
No, standard HND breakers like the HND312T35W are rated for 80 percent continuous load. Eaton circuit breakers with a C prefix, such as CHND, are required for 100 percent continuous operation.
How does the ground-fault function on the HND312T35W improve safety?
The ground-fault protection monitors for leakage current to ground. If a fault is detected, it trips the breaker to prevent equipment damage and reduce fire risks.
Can the HND312T35W trip unit be field tested?
Yes, the Digitrip 310 trip unit includes test points for functional field testing. This requires the use of a compatible Eaton test kit, such as the STK2.
