Product FAQs
7 answersIs the EHD3030 suitable for HVAC and commercial lighting circuits?
Yes, this circuit breaker is both HACR rated for use with heating, air conditioning, and refrigeration equipment, and HID rated for high-intensity discharge lighting loads.
Can the EHD3030 be reverse-fed in a panelboard?
Yes. Eaton Series C F-frame breakers do not have line and load orientation restrictions and are fully suitable for reverse feed applications.
Can I swap the trip unit on this breaker to adjust the protection settings?
No. This model features a fixed thermal-magnetic trip unit that is factory calibrated and non-interchangeable.
Will this directly replace older Westinghouse EHD breakers?
Yes. The Series C product line was originally developed by Westinghouse and later acquired by Cutler-Hammer and Eaton. This unit is a direct physical and electrical replacement for legacy Westinghouse EHD3030 breakers.
Can the EHD3030 be used to replace FDB3030 or FD3030 models?
Yes, it shares the exact same physical dimensions and bolt-on configuration as FDB3030 and FD3030 breakers. However, always verify that your system fault current does not exceed this breaker's interrupt limits, as FD models carry higher interrupt ratings.
How does this bolt-on breaker connect inside the enclosure?
The line side of the breaker bolts directly to the internal bus bars of the panelboard or switchboard, while the load side uses standard mechanical pressure lugs to terminate the outgoing circuit wires.
Are field-installable accessories available for this frame type?
Yes. Because it is part of the standard Series C F-frame family, it can accept a variety of internal accessories such as shunt trips, auxiliary switches, alarm switches, and undervoltage releases.
