Westhomes WCU8-D 4P 20kA Surge Protection Device
Featuring a modular structure suitable for DIN rail mounting, the WCU8-D ensures comprehensive protection across all four conductors (L1, L2, L3, N).
The Westhomes WCU8-D Surge Protection Device (SPD) is a high-performance 4-pole (4P) arrester engineered to deliver superior protection for AC 230V/400V systems operating at 50Hz/60Hz.
Designed with an advanced discharge capacity of 20kA, this model provides dependable surge suppression for three-phase power systems with a neutral connection, effectively mitigating transient over-voltages from lightning induction, power switching, and grid disturbances.
It is ideal for both residential and commercial environments where critical electrical devices, such as air conditioners, televisions, home theatre systems, and computing equipment, require reliable voltage clamping and spike suppression.
The device also serves as a core component in multi-level surge protection systems, and can be easily integrated with other digital or modular circuit protection solutions.
Applications: Three-phase surge protection in homes, offices, and light industrial facilities
Protection Targets: TVS, computers, HVAC systems, audio-visual devices
Integration: Works seamlessly with modular or digital electrical protections
