 | DIN HV Distribution
DIN HV fuses are partial-range high voltage current-limiting fuses for use in distribution circuits from 2.3 - 38kV.
Their compact dimensions and non-venting characteristics make them ideal for restricted enclosures. DIN HV fuses have excellent short circuit performance and good low overcurrent clearing capability. When used in combination with fusible switches with fuse-activated trip feature, full range clearing capability is achieved.
True full-range fuses are available in certain voltage and amp ranges. Please contact Fusetek for more information.
| Features- Highly standardised DIN 43 625 dimensions.
- Excellent short circuit performance. Ceramic bodies, pure silver
elements.
- '30' series fuses have a temperature sensitive striker to protect against
extended overload conditions, or external overheating.
- Sealed for indoor or outdoor use.
- Striker pin can be used for visual indication or mechanical actuation of
other devices. (Std-80N, HD - 120N)
- High amp ratings available for larger installations.
- Fully plated parts for cool running.
| Installation Notes
1. DIN fuses are partial range devices with a minimum interrupting
rating. Care must be taken to ensure that anticipated currents
below the fuse's minimum breaking current (m.b.c) are cleared by
other devices. In this regard, DIN fuses are similar to ANSI - 'E'
rated fuses. Full range DIN fuses are available in limited voltage
and amp ranges. Please contact Fusetek for information.
2. When DIN fuses are used in conjunction with a
Trip-all-phase-device, the minimum breaking capacity of the
switch or contactor must be equal to or greater than the m.b.c of
the fuse.
3. Maximum voltages listed are absolute maximums for safe
operation. Utility system tolerances on voltage must be
considered when selecting a voltage range.
4. When replacing fuses in the field, ensure that contact clips are
clean and free of corrosion, dirt, grease etc... Ensure that the fuse
clips still have good tension. (if the fuse will spin easily in the fuse
clips, the clips have lost their tension and should be replaced)
5. Fuses should be replaced in sets of three to avoid nuisance
blowing caused by element damage.
