WCU8-D 1P 20kA DIN Rail Surge Protection Device
With a maximum discharge current (Imax) of 20kA, the WCU8-D offers dependable surge suppression performance for single-phase applications, is also ideal for terminal protection where refined voltage control is critical.
The Westhomes WCU8-D Surge Protection Device (SPD) is a compact and reliable 1-pole (1P) surge arrester engineered for DIN rail mounting, ideal for AC 50Hz/60Hz power systems with 230V and 400V operational voltage.
Designed for both residential and light commercial use, this SPD provides targeted protection against transient over-voltages caused by lightning surges and switching operations.
It acts as the first line of defense in safeguarding sensitive electronics like televisions, computers, sound systems, air conditioners, and other household appliances by minimizing over-voltage exposure and extending equipment lifespan.
Its modular structure allows easy integration into existing power panels and compatibility with digital and analog protective devices.
Mounting Style: Standard DIN rail
Application: Surge protection for residential and light commercial systems
Protected Devices: TVS, PCS, air conditioners, audio systems, and more
Compatibility: Works with modular and digital protection modules
Installation Location: Power panels, control cabinets, or terminal circuits
