DC Surge Protective Device (SPD) Type 1+2 HKB/HKU-PV40 | 3P 40kA DC1000V Lightning Arrester for PV Systems | Red=Replace Indicator, CE Certified

☀️ Ultimate DC Surge Protection for High-Voltage Solar Arrays – Type 1+2 Combined

• Hybrid A/B Type (Type 1+2): Protects against both direct lightning strikes (10/350µs) and switching surges (8/20µs).

• 1000V DC Rating: Designed for commercial and utility-scale PV systems up to 1000V.

• 3-Pole Configuration: Protects positive (+), negative (-), and ground – complete isolation.

• 40kA Surge Capacity: High-energy dissipation for the most demanding installations.

• Red=Replace Visual Indicator: At-a-glance status monitoring – green = good, red = replace.

• CE Certified: Meets European safety standards for photovoltaic applications.
