What is the product lifespan? Does it need to be replaced regularly?
Resettable overvoltage and undervoltage protectors have a certain service life (for example, the electrical life is typically over 100,000 cycles). We recommend regular inspection and replacement based on usage to ensure reliability.
Can circuit breakers replace overvoltage and undervoltage protectors?
No. Circuit breakers and overvoltage and undervoltage protectors provide different protections. Circuit breakers primarily interrupt short-circuit currents, tripping to protect equipment when a short-circuit occurs. Overvoltage and undervoltage protectors, on the other hand, operate when they detect system voltage anomalies (over- or under-voltage). While the two functions complement each other, they cannot replace each other.
What should I do if the protector itself malfunctions?
If you encounter a malfunction that cannot be resolved yourself, or if the product is severely damaged and malfunctions, please stop using it immediately and contact our professional after-sales service personnel for inspection and repair. Never disassemble or repair the product yourself, as this may cause safety hazards or further damage to the product.
Whatcertifications or standards does the product have?
Most products have CE and 3C certifications. Different products have different certifications. Please contact us for specific information.
