Protector combinado de sobretensión y corriente de rayo DEHN DCB YPV 1200 para instalaciones fotovoltaicas (900070)

The DEHN DCB YPV 1200 stands out as a combined lightning current and surge arrester specifically engineered for photovoltaic systems, integrating Type 1 and Type 2 protection in a single compact unit. Its spark-gap-controlled, short-circuit-free technology ensures reliable protection without the risk of short circuits, making it a robust choice for demanding PV installations.

Highlights

• Combined Type 1 + Type 2 surge protection for PV systems
• High maximum continuous operating voltage of 1200 V DC
• Lightning impulse current of 6.25 kA per pole (10/350 µs)
• Potential-free remote signalling contact for status monitoring
• DIN rail mountable for easy installation

In daily use

Designed for photovoltaic systems, this arrester protects against both direct lightning strikes and surge voltages. Its three protection paths (DC+/PE, DC-/PE, DC+/DC-) ensure comprehensive coverage, while the remote signalling contact allows integration into monitoring systems. The unit operates reliably in temperatures from -40 °C to +80 °C and supports conductor cross-sections up to 35 mm² solid or 25 mm² stranded.
