Weidmüller VPU PV I+II 0 1000 dispositivo de protección contra sobretensiones, tipo 1+2, 1000 V DC, 20 kA, 3 polos, enchufable, carril DIN

The Weidmüller VPU PV I+II 0 1000 is a high-performance surge protective device (SPD) designed specifically for photovoltaic systems. Combining Type 1 and Type 2 protection in a single pluggable module, it safeguards PV installations against both direct lightning strikes (10/350 µs) and switching surges (8/20 µs). With a maximum continuous operating voltage of 1060 V DC and a nominal discharge current of 20 kA per pole, this 3-pole SPD ensures reliable overvoltage protection for your solar power system.

Advantages

• Dual Type 1+2 protection in one compact device
• Pluggable design for easy replacement without rewiring
• High energy handling capacity: Iimp 6.25 kA (10/350 µs) per pole
• Clear optical fault indication (green/red) for quick status checks
• Suitable for high-voltage PV systems up to 1000 V DC
