Popular Electric WCU8-C 4P 40kA Surge Protection Device
The Popular Electric WCU8-C Surge Protection Device (SPD) is a premium-grade 4-pole (4P) surge arrester designed for AC 50Hz/60Hz systems with 230V and 400V rated operational voltage.
The WCU8-C Surge Protection Device delivers reliable protection against transient over-voltages caused by lightning strikes, power grid fluctuations, and electrical switching surges.
Engineered to handle a maximum discharge current of 40kA, the WCU8-C ensures the safe operation of electrical infrastructure by efficiently suppressing surge energy at the main power entry point or terminal protection level.
It plays a critical role in step-down protection strategies, lowering the over-voltage category to safeguard downstream devices such as televisions, audio systems, HVAC units, computers, and other sensitive electronics.
The modular design allows seamless integration with digital and analog protective systems, making it ideal for residential, commercial, and light industrial installations requiring comprehensive surge protection across all four wires (L1, L2, L3, N) in a three-phase + neutral system.
Application: Lightning and surge protection for three-phase power systems
Protection Scope: TV sets, computers, HVAC units, sound systems, and other digital electronics
Integration: Compatible with modular and digital protection schemes
Installation Points: Main distribution boards and terminal circuits
