Product FAQs
7 answersWhich panelboards accept the EHC2050 circuit breaker?
This Series C F-frame breaker is designed for bolt-on installation in Eaton, Cutler-Hammer, and legacy Westinghouse Pow-R-Line panelboards, switchboards, and motor control centers.
What is the modern replacement for the legacy EHC2050?
The EHC2050 is an out-of-production legacy breaker. The Eaton EHD2050 serves as the direct, physically and electrically interchangeable replacement for retrofits and upgrades.
What type of wire can be terminated on the EHC2050 lugs?
The standard lugs accept 14 AWG to 1/0 AWG conductors and are rated for both copper and aluminum wire. If using aluminum conductors, an appropriate joint compound must be applied prior to termination.
Are the thermal and magnetic trip units adjustable on this breaker?
No, the EHC2050 features fixed thermal and fixed magnetic trip functions. The trip settings are factory calibrated and cannot be modified in the field.
Can the EHC2050 be applied in direct current (DC) systems?
Yes, it carries a 250VDC rating with a 10kAIC interrupting capacity. When applying this breaker in DC systems, the ratings apply to substantially non-inductive circuits.
Is the EHC2050 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
Is the EHC2050 suitable for reverse feed applications?
Yes, this thermal-magnetic breaker is reverse feed capable, allowing line and load connections to be swapped if required by the specific panel or enclosure configuration.
