Series Overview
Series Overview
Absolute Safety and Speed
- The 3NE semiconductor - protected fuse provides optimal protection for power - class semiconductor components in frequency converters and soft starters.
- Considering the low thermal energy of semiconductor components and their sensitivity to overvoltage, they can quickly break. No other protection equipment can interrupt short - circuit currents as reliably as they do.
- The 3NE semiconductor - protected fuse has much higher restrictions on the current density and temperature of the fuse element than traditional low - voltage fuses used to protect cables and conductors. That is to say, the fuse is always in a standby state. This ensures that the fuse can make the best response when a fault occurs.
- Due to the limitations of its special structure, the 3NE semiconductor - protected fuse can also be used in cyclic circuits without reducing the rated current. Due to their high cyclic circuit capacity and rated load, they provide the best I²t value, suitable current - limiting and protection.
3NE Fuses Provide Short - Circuit Protection for Frequency Converters and Soft Starters
- All power - class semiconductor components used in frequency conversion and transmission devices, such as diodes, thyristors, gate - turn - off thyristors (GTO), require fast segment protection to achieve their low - thermal effects.
- 3NE fuses are most suitable for this type of application needs (these fuses provide ultra - fast semiconductor protection).
- The fault conditions of short circuits are as follows:
- Internal short circuit: A fault of semiconductor components causes an internal short circuit of the frequency converter.
- External short circuit: A fault of the load causes a short circuit at the output end of the frequency converter.
- Inverter communication fault: Suppose there is a communication fault when the frequency converter control system is in the inverter mode.
- When a fault occurs, it will cause a short circuit of the frequency converter in the DC and AC power systems.
- When applying type aR frequency converter fuses, the overload protection of the frequency converter (up to 3.5 times the rated current) can be realized by conventional protection devices (such as thermal overload relays). The overload protection of frequency converters with closed - loop control can be realized by current measuring devices (excluding general - purpose fuses).
- The gS - type 3NE1 - 0 fuse, in addition to being suitable for semiconductor protection, also has the functions of overload and short - circuit protection for cables, conductors, and busbars. Other functions of 3NE fast fuses are of gR - type characteristics. As long as the rated current of the 3NE fast short - circuit fuse is within In ≤ Iz (DIN VDE 0100 - 430), the overload protection can function normally.
- 3NE fuses implement the following standards:
- IEC 60269 - 4
- EN 60269 - 4
- If the product selection, ordering data, and characteristic curves are specified, 3NE fuses can also implement the following standard rules:
- IEC 60269 - 2 - 1
- DIN VDE 0636 - 201
- (Suitable for the installation of LvHRC fuse bases referring to the VDE 0636/201 standard, as well as fuse disconnector switches and switch - fuse groups)
- The following SITOR fuses and LvHRC fuse bases have passed certification:
- IEC 60269 - 4 - 1
- VDE 0636/401
- (Suitable for busbar connection) According to the IEC 60269 - 2 - 1 standard, with 110mm screw fixing holes, sizes 1 to 3 SITOR fuses can also be installed in LvHRC fuse bases, as well as fuse - type disconnector switches and switch - fuse groups.
- All 3NE fuses with a rated voltage Un < 1000V are certified with a certification mark executed in accordance with the Low Voltage 73/23/EwG directive. The mark indicates that all indicators of the product comply with the relevant requirements of the "Directive".
