Product FAQs
8 answersWhich panelboards accept the RHF3050 circuit breaker?
This unit-mount breaker is designed for Eaton Pow-R-Line C panelboards. It is also backward compatible with legacy Westinghouse and Cutler-Hammer panelboards configured for RE Frame breakers.
Is the RHF3050 a direct replacement for older HF-series breakers?
Yes, the RHF3050 serves as a direct, seamless replacement for the obsolete HF3050 molded case circuit breaker.
What does the LI trip function specify for this breaker?
The LI code indicates that the breaker provides Long-Time thermal protection for sustained overloads and Instantaneous magnetic protection for short circuits. Both the thermal and magnetic trip points are fixed.
How is the RHF3050 secured within the panelboard?
As a unit-mount breaker, it requires bolted connections directly to the panelboard bus or mounting chassis. It is not a plug-on or snap-in device.
What frame size does the RHF3050 belong to?
This breaker is part of the Eaton RE Frame group, which is a legacy molded case circuit breaker footprint distinct from the standard F-Frame series.
Is the RHF3050 suitable for reverse-feed applications?
Yes, this thermal-magnetic RE Frame breaker features reverse-feed capability, allowing it to be back-fed when permitted by local electrical codes and panelboard labeling.
Can the trip curve be adjusted for specific load requirements?
No, the RHF3050 features fixed thermal and fixed magnetic trip elements. It does not offer the adjustable dials or switches found on breakers with electronic trip units.
Is this breaker rated for heating, air conditioning, and refrigeration equipment?
Yes, the RHF3050 is HACR rated, making it suitable for use with commercial HVAC and refrigeration motor loads.
