Westhomes WCU8-PV-40 DC SPD 600V
Westhomes WCU8-PV-40 single-phase DC SPD delivers 40kA surge protection at 600VDC for solar systems & household power distribution. DIN rail mount, 34S MOV, seamless module replacement.
Prioritize PV system safety with the Westhomes WCU8-PV-40 DC SPD. Delivering 40kA robust protection at 600VDC, this T2 device ensures stable operation for solar inverters and power distribution units.
Key Features：
PV-Specific DC Design: Optimized for direct current (DC) photovoltaic systems, supporting a maximum continuous operating voltage of 600V DC, specifically tailored to solar panel array requirements.
Dual Grade Protection: Boasts a nominal discharge current of 20kA (In) and a maximum discharge current of 40kA (Imax), effectively absorbing high-energy surges and lightning strikes.
Real-time Monitoring: Integrated Status Indicator allows quick visual inspection of the SPD’s operational health, ensuring the protection layer is active when needed.
Efficient MOV Technology: Utilizes high-quality 34S MOV (Metal Oxide Varistor) core for rapid voltage response, clamping the surge voltage down to a safe 3.0kV to protect sensitive electronics.
Applications:
Residential Solar PV Systems
Commercial Solar Farms
Solar Energy Storage Systems
