AZO DIGITAL Protector contra sobretensiones DC Tipo 2 1000V 20kA 3 polos para instalaciones fotovoltaicas

The AZO DIGITAL AZO00D1240 is a high-performance Type 2 DC Surge Protective Device (SPD) designed specifically for photovoltaic (PV) systems. It provides reliable protection against transient overvoltages caused by lightning or switching operations, safeguarding your solar installation and connected equipment. With a maximum continuous operating voltage of 1000 V DC and a nominal discharge current of 20 kA, this 3-pole SPD ensures robust protection in both common and differential modes.

Advantages

Integrated thermal disconnector for enhanced safety; visual fault indication (green/red flag) for easy status monitoring; compact DIN rail mounting for simple installation; high surge handling capacity with fast response time (<25 ns); flame-retardant thermoplastic housing (UL94 V-0).

Suitable for

• Photovoltaic (PV) systems up to 1000 V DC
