NEW CHT1-B40KA 4p Surger Protective Device(SPD)

Surge refers to a sudden increase in voltage or current that occurs in an electrical system, usually for a short period of time. Surges can be caused by a variety of factors, including lightning strikes, switch operations, and electrical equipment failures. The magnitude of the surge voltage may be much higher than the rated voltage of the device, resulting in serious consequences such as device damage, data loss, and even fire. The use of surge protectors becomes necessary.

Advantages

4p surge represents a higher surge voltage level and is suitable for environments subject to severe disturbances, such as civil overhead lines, unprotected high-voltage substations, etc. In these environments, the equipment may face high-intensity surge shocks from lightning, power system switching operations, etc. By conducting 4p surge immunity tests, the reliability of the equipment in extreme electromagnetic environments can be ensured.

Reduce failure rate: The internal circuits and components of the equipment that has undergone 4p surge testing have been strictly screened and verified to maintain normal operation under high voltage shocks. This helps to reduce the failure rate of the equipment and improve the stability and service life of the equipment.
