Description
EATON Current Limiting Fuse, Type HLE Helix E-Rated Medium Voltage 1-Barrel, 40 A, 15.5 kV, 63 kA Interrupt, Class: E, 50/60 Hz, 300 s Response, 18.87 in L x 6 in W x 6 in H Body Size
Features:
- Current limiting e-rated medium voltage fuses are defined by their melting time-current characteristic that permit their electrical interchangeability with other fuses of the same e-rating
- E-rated fuses must have a defined current response time specified by ANSI C37.46
- E-rated fuse of 100 A and below must melt in 300 s at an RMS current within the range of 200 to 240% of the fuse's nameplate current rating
- E-rated fuses are physically dimensioned for easy installation in existing hardware
- Current limiting fuses provide positive interruption even on low fault currents
- The fuse limits the magnitude of electro mechanical stresses in the protected apparatus
- Open fuse indicator speeds trouble shooting by providing a positive visual indication of fuse operation
- HLE short construction
Applications:
For use in medium voltage feeder circuit protection, medium voltage metal-enclosed switchgear, medium voltage transformer primary protection, medium voltage switches and indoor/outdoor applications
Standards/Approval:
- ANSI C37.46
- IEEE C37.41
- UL Guide JEEG, File E240398
Warranty:
1 year
