SARAH Electric's high quality 220V Low Voltage Surge Arrester, specifically models YH1.5W-0.28/1.3 and YH1.5W-0.5/2.6, are crucial devices used in the power system to protect electrical equipment from damage caused by lightning or operational overvoltages. For this product, we use zinc oxide valve plates as the core component, featuring excellent non-linear voltage current characteristics.
SARAH Electric is a supplier of durable 220V Low Voltage Surge Arrester, which is designed for low voltage power distribution systems and is useful for 380V/220V AC power grids. It is widely used for lightning protection and overvoltage protection of equipment such as distribution cabinets, transformers, motors, and capacitors. The structure is compact and easy to install. It is equipped with a screw type terminal at the top, which can be directly connected to wires or busbars. The bottom features a metal flange or threaded structure, making it easy to fix on supports or equipment.

Common Faults and Solutions
Failure Modes
Causes
Symptoms
Action
MOV aging/degradation
Cumulative damage from repeated surge strikes
Increased leakage current; overheating
Replace SPD module
Thermal runaway
Sustained overvoltage → increased leakage current → rising temperature (vicious cycle)
Casing becomes hot to the touch; discoloration
Disconnect power immediately and replace
Short-circuit failure
MOV breakdown/short circuit
Backup protection operates (tripping/fuse blows)
Replace SPD; check backup protection
Open-circuit failure
Thermal trip mechanism disconnects
Indicator window turns red; protection lost
Replace SPD module
External short circuit
Wiring errors or insulation damage
Backup protection operates
Check wiring; replace SPD
GDT follow current
Gas discharge tube fails to self-extinguish after conduction
Power-frequency follow current persists
Check for proper MOV coordination
