1 question about the product
 

Combined protection set against transient (earth arrester) and permanent overvoltages, associated with a 2-pole cut-off device (IGA) with a breaking capacity of 10kA according to UNE EN60898, curve "C".

The function of this protection module is to disconnect the single-phase electrical system when it is subjected to a voltage greater than it should receive, on a continuous basis, and to derive to ground the transient overvoltages caused by lightning strikes or the switching of electrical distribution lines.

This device, very compact and simple to install, provides very high protection, both against transient or permanent overvoltages, as well as against line overvoltages, by incorporating an IGA (magnetothermic) with a breaking capacity of 10kA. It has a visual indicator of the cutting status.

Suitable for use in domestic installations, electric vehicle charging points and industry.

The supply includes:

  • 2 Pole IGA (single phase): 2x25A.
  • Permanent surge protector.
  • Transient surge protector (ground arrester).

 

The entire assembly is supplied fully wired.

Neutral location on the right side, it is mandatory to respect the neutral position even if the IGA is 2-pole protected.

Technical characteristics:

  • Firing curve: "C".
  • Permanent upper trip voltage: 265Vac.
  • Permanent overvoltage response time:
    • 275Vac: approx. 7s.
    • 300Vac: approx. 3s.
    • 350Vac: approx. 0.5s.
    • 400Vac: approx. 0.15s.
  • Nominal transient discharge intensity (In): 5kA.
  • Maximum transient discharge intensity (Imax): 15kA.
  • Protection voltage (Up): =
  • Device type (class): II.
  • Maximum cable section in terminals: 10 mm 2 (IGA) 6 mm 2 (module).
  • Number of modules occupied on DIN rail: 4.
  • Regulations: EN 60898 / EN 50550 / IEC 61643-11.
  • Marking: CE.

 

Note: The surge protection capability is highly dependent on the quality of the ground.

Questions

Question
Buenos días , estoy pensando en montar el limitador combinado contra sobretensiones permanentes y transitorias, pero tengo alguna duda. En caso de que se active el limitador de sobretensiones transitorias, quedaría interrumpida la salida del IGA?, es decir, para volver a tener corriente aguas abajo, tendría que sustituir el cartucho? La otra duda que tengo es si ustedes venden los cartuchos del Limitador de sobretensiones transitorio, por separado, para poder reactivar la protección.. Muchas gracias de antemano. Un saludo
Answer

Buenos días,

En respuesta a su pregunta:

Buenos días , estoy pensando en montar el limitador combinado contra sobretensiones permanentes y transitorias, pero tengo alguna duda. En caso de que se active el limitador de sobretensiones transitorias, quedaría interrumpida la salida del IGA?, es decir, para volver a tener corriente aguas abajo, tendría que sustituir el cartucho?

El dispositivo protector de sobretensiones transitorias, como se puede ver en el esquema, se encuentra conectado a la entrada del dispositivo, esto quiere decir, que cuando actúa, deriva a tierra la sobretensión transitoria sin activar el IGA, no tendría que realizar ninguna acción para restablecer la tensión. Solo se producirá disparo del IGA por acción del protector de sobretensiones permanentes, en caso de actuar este si tendría que volver a activar el IGA para restablecer el suministro de tensión.

Con relación a la "sustitución del cartucho", cuando las sobretensiones transitorias sean las habituales, de relativamente poca energía", no tendrá que sustituir el cartucho, pero se ira deteriorando y con el tiempo se tendrá que sustituir, aparecerá una indicación en "rojo". En caso de disparo por rayo cercano, habitualmente si hay que sustituirlo, y en muchas ocasiones, todo el dispositivo.
