ITE breaker rating
(OP)
Can anyone tell me where to find interrupt rating data for ITE 5kv HK model breakers?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: ITE breaker rating
5-HK-75 (75 MVA)
5-HK-250(250 MVA)
5-HK-350(350 MVA)
If you can let me know what class you have, I can post the detailed ratings.

RE: ITE breaker rating
Test Basis for both is ANSI-Symmetrical current basis.
5-AK-250:
MVA = 250 MVA
Nom kV = 4.16 kV
Max kV = 4.76 kV
K Fact = 1.24
Close & Latch = 58 kA
Interrupting Amps at Max kV = 30.3 kA
Max Interrupting Amps = 51 kA
Interrupting Time = 5 Cycles
5-AK-350:
MVA = 350 MVA
Nom kV = 4.16 kV
Max kV = 4.76 kV
K Fact = 1.2
Close & Latch = 78 kA
Interrupting Amps at Max kV = 42.5 kA
Max Interrupting Amps = 37.5 kA
Interrupting Time = 5 Cycles
