Product FAQs
5 answersWhat panelboards are compatible with the HFDE322533L?
This F-Frame breaker is designed for use in Eaton Series C panelboards, motor control centers, and switchboards. It utilizes a standard unit mount configuration and bolts directly into compatible enclosures.
What does the LS designation mean on the trip unit?
The LS indicates that the Digitrip 310+ electronic trip unit features adjustable Long-Time (L) and Short-Time (S) pickup and delay settings. This allows electricians to precisely coordinate the breaker's trip curve with other protective devices in the electrical system.
How does the HFDE frame differ from standard FDE breakers?
The 'H' in the HFDE prefix indicates a high interrupting capacity. While standard FDE breakers typically offer a 35kA rating at 480VAC, the HFDE322533L provides a 65kA interrupting capacity at 480VAC for systems with higher available fault currents.
Can I use aluminum wire with the factory lugs on this breaker?
Yes, the standard line and load lugs included with this breaker are dual-rated for both copper (Cu) and aluminum (Al) conductors ranging from 4 AWG to 4/0 AWG.
Does this electronic trip breaker require an external power supply to operate?
No, the Digitrip 310+ electronic trip unit is self-powered by the current flowing through the breaker. It does not require a separate external power source to provide standard overcurrent and short-circuit protection.
