LUHFSER distribution dropout fuse cutout for expulsion fuses.

1. Nominal current

50, 100 and 200 A distribution dropout fuse cutout

2. Nominal voltage in kV.

The rated voltage of the dropout fuse cutout is defined as a function of the phase-to-neutral voltage and the phase-to-phase voltage.  

3. Interruption capability

It is the maximum fault current that the dropout fuse cutout can interrupt without damage.

LUHFSER expulsion fuses manufactured by ELECTRICOS INTERNACIONAL SAS, are installed in distribution dropout fuse cutout for overhead networks and protect distribution transformers, overhead lines, branch lines, reclosers and other devices, in circuits with voltages in the range of 6 to 38 Kv, against overload and short-current faults.  

USES Selection, application and coordination of Luhfser brand fuse wires.

• fuses to protect the transformer:

Protección de la sobrecarga Protección de cortocircuito Capacidad para soportar las corrientes de entrada o irrupción y sobretensiones.

• Coordination of fuses with each other
• Selection of fuses on feeder lines
• Fuse selection for recloser coordination.
• Capacitor bank protection reliability conditions for proper operation

Does not melt when it should not

La seguridad es el aspecto de la confiabilidad que expresa el grado de certeza de que el fusible no operara incorrectamente bajo condiciones normales. Se mide como la probabilidad de que el sistema de protecciones no presente actuaciones de falla o que actúen otras protecciones diferentes a las que debieron actua

Does not melt when it should not

Reliability is the aspect of reliability that expresses the degree of certainty that the protection system will operate correctly in the presence of an abnormal condition or fault, taking the necessary actions in this situation. It is measured as the probability that the system will act effectively in the presence of a fault.

LUHFSER expulsion fuses should be installed according to the following recommendations:

• Removal of the washer is prohibited
• Removal of the tube is prohibited
• Weakening the cable is prohibited
• Weakening the wire is prohibited
• It is prohibited to cut the cable at the lower contact of the fuse holder.

In a three-phase circuit, it is recommended that after a fault occurs and one or two LUHFSER fuses operate, they should all be replaced since the remaining fuses, even if they appear to be intact, may have suffered deterioration of the fuse wire and alter the current vs. time fusing characteristics.

Para la identificación del tipo de fusible según la corriente nominal, se recomienda fijar o ponchar una Shakira de color en el extremo del cable del fusible. El material debe ser polimérico, resina o fibra con propiedades de protección para los rayos UV que mantenga el color de la Shakira con el tiempo

The effects of uses contrary to those indicated by the manufacturer for Colombia shall be the responsibility of the installer or user of the product.

DANGER OF ELECTROCUTION AND ESCAPE.

1. LUHFSER fuses cannot protect personnel from electrocution.
2. Distribution dropout fuse cutout can expel hot gases and particles at high velocity during interruption.
3. When engaging a distribution dropout fuse cutout , clear all personnel from the work area.
4. Ejection of the dropout fuse cutout can cause serious injury. Do not align with the pole and fuse holder. Stay clear of the conical space under the fuse holder.
