U4 surge protector device, referred to as SPD, is suitable for AC 50/60Hz, rated voltage does not exceed 600V low-voltage power supply system, complies to both UL1449 and IEC 61643-11 standards.
The main function is to suppress the transient overvoltage below the equipment impulse overvoltage, discharge the surge energy, so as to protect the safety of the system circuit and equipment.

Miniature circuit breakers are widely adopted. They are used for branch circuit protection in many electrical systems. However, as solar photovoltaic technology continues to expand rapidly, one question arises: Can I use a general miniature circuit breaker for PV?
In today’s digital age, data centers have become critical infrastructure. They enable our increasingly online lives and economies. They store massive amounts of data and power cloud services and applications.
An RMU, or ring main unit, is a type of medium-voltage switchgear. It consists of one or more circuit-breaker units with associated disconnectors, earthing switches, and instrument transformers.
