The Westhomes WCU8-B Surge Protection Device is a high-performance 3-pole (3P) SPD engineered to protect power systems operating at AC 50Hz/60Hz with rated voltages of 230V and 400V.
Designed to suppress transient over-voltages from lightning strikes and electrical switching surges, WCU8-B 3P 60kA Surge Protection Device for residential, commercial, and industrial applications.
Westhomes WCU8-B 3P 60kA Surge Protection Device for AC 230V/400V Power Systems
With a maximum discharge current (Imax) of 60kA, the WCU8-B ensures efficient voltage clamping, safeguarding your electrical network and connected devices from damaging surges.
When installed at terminal points, it effectively reduces residual voltage, offering secondary protection for high-value electronics such as TVS, air conditioners, audio equipment, and computers.
The WCU8-B is suitable for environments requiring a higher over-voltage category, acting as a step-down protection layer in power distribution systems.
It can also be integrated with other modular or digital protective devices, forming a complete and adaptive surge protection solution.
Delivering reliable surge suppression and improved equipment longevity, the Westhomes WCU8-B 3P 60kA SPD is the smart choice for enhanced power safety in multi-phase systems.
Application: Power line surge protection against lightning and switching over-voltage
Protection for: Televisions, high-fidelity audio systems, HVAC units, computers, and more
Modular Design: Compatible with digital and modular protective components
Installation: Ideal for main power distribution panels and terminal protection
