Product FAQs
6 answersWhat does the "V" suffix indicate on the Eaton EHD2030V circuit breaker?
The "V" suffix indicates that this breaker is calibrated for a 50°C (122°F) ambient temperature. This makes it suitable for marine applications, high-temperature industrial environments, or enclosures where standard 40°C calibrated breakers might experience nuisance tripping.
Which panelboards are compatible with the EHD2030V breaker?
This F-Frame breaker is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It features a bolt-on mounting style for secure connections to the busbar.
What wire sizes are accepted by the lugs on the EHD2030V?
The standard lugs on this 30A breaker accept wire gauges from 14 AWG up to 1/0 AWG. Ensure you torque the terminals to the manufacturer specifications printed on the breaker label to prevent arcing or thermal buildup.
Can I use the EHD2030V to replace a standard EHD2030 breaker?
Yes, the EHD2030V shares the same physical dimensions, mounting hardware, and electrical ratings as the standard EHD2030. The primary difference is its 50°C ambient calibration, which provides an added margin against nuisance tripping in warmer environments.
How does the thermal magnetic trip unit function on this breaker?
The EHD2030V features a fixed thermal and fixed magnetic (LI) trip unit. The thermal bimetal component provides long-time protection by heating up and tripping during sustained overloads, while the magnetic solenoid provides instantaneous protection against sudden short circuits.
Can the EHD2030V be used in direct current (DC) systems?
Yes, this breaker is rated for up to 250VDC with a 10 kAIC interrupting capacity. When installing in DC systems, ensure your wiring configuration and load calculations comply with local electrical codes for DC fault protection.
