B-LINE EHD3050A06 – Frequently Asked Questions
1) What is the interrupting rating of the Eaton EHD3050A06 breaker at 240V and 480V?
The EHD3050A06 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-type breaker is not the right frame for that location. It runs on 50/60 Hz systems, so it works on both domestic and export power.
2) Is the EHD3050A06 a three-pole 50 amp breaker?
Yes, three-pole, 50 amp continuous rating. It is an F-frame EHD-type unit in Eaton's Series C line, so it is sized for three-phase branch or feeder duty at 50A.
3) Does the EHD3050A06 come with an auxiliary switch, or do I order one separately?
The auxiliary switch is already built into this one: a 1A-1B rear-mounted switch with a right-hand pigtail. That gives you one normally-open and one normally-closed contact for remote breaker status, so you do not need to add a field-installed accessory kit to get position indication.
4) Is the EHD3050A06 adjustable trip or fixed?
Fixed thermal, fixed magnetic. There is no adjustable instantaneous or long-time dial on this breaker, so the 50A trip curve is what you get out of the box. If your coordination study calls for an adjustable magnetic setting, you need a different trip unit, not this one.
5) Is this a complete breaker or just a replacement trip unit?
It ships as a complete breaker, not a trip unit or an interchangeable module. Line and load connections, housing, and the trip mechanism are all one assembly, so it drops into an existing F-frame EHD application as a whole unit. Terminals supplied are load side.
6) How much space does the EHD3050A06 need in a panel or enclosure?
The breaker measures 6 in height, 4.13 in width, and 3.38 in length, and weighs 4.5 lb. Allow for the rear pigtail on the auxiliary switch when you are laying out wiring gutter space behind the unit.
7) What part number do I order for the Eaton Series C 50A three-pole breaker with aux switch?
The catalog number is EHD3050A06. The A06 suffix is the factory-installed auxiliary switch option, so ordering the plain EHD3050 gets you the same 50A three-pole breaker without that switch.
8) Can I use the EHD3050A06 on a 480V three-phase feeder?
Yes, within its 14 kAIC rating at 480 Vac. On 240 Vac systems the same breaker carries 18 kAIC. It is a three-pole unit at 50A with a fixed thermal-magnetic trip, so it suits a 480V three-phase feeder or branch where the fault duty stays under 14 kA.
