B-LINE EHD3030S05 – Frequently Asked Questions
1) What is the interrupting rating of the Eaton EHD3030S05 breaker at 240V and 480V?
The EHD3030S05 is rated 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. If your available fault current at the panel exceeds those numbers, this EHD frame is not the right breaker for that location and you need a higher AIC frame or series-rated combination.
2) Is the EHD3030S05 a three-phase breaker and what amperage does it carry?
Three-pole, 30 amp. That makes it a three-phase branch or feeder breaker for a 3-phase panel or for a 3-pole disconnect on motor and equipment circuits. It is rated 50/60 Hz.
3) Do I need to order a trip unit or accessories separately with the EHD3030S05?
No. It ships as a complete breaker with a fixed thermal, fixed magnetic trip unit built in. There is no interchangeable rating plug and no trip setting to dial in, so the 30A rating is what you get. Load side terminals are included.
4) Will an EHD frame breaker fit in the space where my old one was?
The EHD3030S05 is an F-frame, Series C molded case breaker measuring 6 in by 4.13 in by 3.38 in and weighing 4.5 lb. F-frame is a specific Eaton mounting footprint, so it drops in where another F-frame EHD was installed. It will not fit a panel interior prepped for a different frame size.
5) Can I use this 30A breaker at 480 volts or only 240?
Both, with different interrupting capacity. The EHD3030S05 gives 18 kAIC at 240 Vac and drops to 14 kAIC at 480 Vac. On a 480V system, size your fault current study against the 14 kAIC figure.
6) Is the EHD3030S05 adjustable if the motor nuisance trips on inrush?
No adjustment is available. The trip is fixed thermal and fixed magnetic, so the instantaneous pickup cannot be raised. If a motor load trips on starting inrush, the fix is a different breaker type with an adjustable magnetic trip, not a setting change on this one.
