Mersen

Mersen es nuestra colección de fusibles y protecciones eléctricas para instalaciones solares e industriales. Incluye cartuchos y portafusibles de alto rendimiento para seccionamiento y protección frente a sobrecargas y cortocircuitos, con gamas específicas para CC fotovoltaica (gPV) y para CA (gG).

Elígela cuando necesites seguridad certificada, curvas de fusión estables y formatos normalizados (p. ej., 10x38, 14x51, 22x58). Nota: en esta categoría encontrarás referencias gG 690 V para cuadros de corriente alterna y, según disponibilidad, fusibles gPV para corriente continua FV.

What is the Mersen collection and what does it cover?

The Mersen collection brings together industrial-quality fuses, cartridges, and fuse holders for the protection of lines, equipment, and solar strings. Mersen manufactures specific ranges: gPV (photovoltaic DC up to 1000–1500 V) and gG (AC distribution up to 690 V), as well as disconnection solutions and accessories. In this family you will find, among others, 22x58 gG 690 V references designed for main and sub-distribution boards.

Advantages and limitations

  • Precise melting curves: high breaking capacity and selectivity compared to downstream circuit breakers.
  • Standardized formats (10x38, 14x51, 22x58) compatible with standard fuse holders.
  • gPV options for photovoltaic DC and gG for AC.
  • Limitations: choose the correct type (gPV vs gG), appropriate rated voltage and breaking capacity; do not interchange AC/DC uses outside specification.

Applications

  • Protection of PV strings (gPV) in combiners and DC boxes.
  • Protection of lines and loads in distribution boards (gG 690 V).
  • Safe disconnection during maintenance and O&M operations.

How to choose the right Mersen fuse

  • Network type: gPV for photovoltaic DC; gG for general AC.
  • Rated voltage: equal to or higher than the service voltage (e.g., 690 V AC for gG; 1000/1500 V DC for gPV).
  • Rated current: define according to line/string current and temperature conditions (do not oversize excessively).
  • Breaking capacity: check the breaking capacity against the expected short-circuit current.
  • Format: 22x58, 14x51, 10x38, etc., compatible with the available fuse holder.

Indicative specifications (highlighted series)

Types gPV (DC PV) / gG (AC distribution)
Rated voltage Up to 690 V AC (gG) / up to 1000–1500 V DC (gPV)
Formats 10x38 · 14x51 · 22x58 (ceramic cartridge)
Breaking capacity High Icc according to standard (see each model's datasheet)
Accessories Fuse holders, disconnectable bases, blown fuse indicators

Best practices

  • Select the correct type (gPV/gG) and check the circuit voltage.
  • Coordinate with circuit breakers and disconnectors to ensure selectivity.
  • Install in DC boxes or AC boards with adequate heat dissipation.
  • Record Isc/Voc values (in PV) and estimated short-circuit currents to validate breaking capacity.

Quick comparisons

  • 22x58 gG 690 V: distribution and line protection in industrial boards.
  • 10x38 gPV: individual PV strings in combiner boxes.
  • 14x51 gPV/gG: compromise between size and breaking capacity.
