3-Pole Type 1+2 DC Surge Protection Device for 1000V Photovoltaic Circuits
SPV340T 3-Pole Type 1+2 DC Surge Protection Device
The Live Electrical SPV340T 3-Pole Type 1+2 DC Surge Protection Device is designed to protect photovoltaic DC circuits up to 1000V DC from both direct lightning currents (Type 1) and indirect or switching surges (Type 2). It provides comprehensive protection for DC positive, DC negative, and protective earth (PE) conductors in solar PV installations.
Engineered for high-risk environments and lightning-prone locations, the SPV340T combines robust discharge capability with fast response time, making it suitable for DC combiner boxes and photovoltaic distribution boards in commercial and industrial PV systems.
Key Features – SPV340T 3-Pole Type 1+2 DC Surge Protection Device
- Combined Type 1+2 DC surge protection for lightning and switching events
- High-energy varistor technology for effective surge absorption
- Ultra-fast response time of less than 25 nanoseconds
- Designed for high-exposure photovoltaic installations
