TOMZN AC SPD 50KA T1 T2 385V 255V House Surge Protector AC Surge Protective Device lightning arrester (TZG40-C) 1P+NPE

The modular design with plug-in inserts allows simple and quick replacement of function modules in case of MOV is beyond if its lifespan due to often occurrence of overvoltage peaks.

The design of AC Surge Protective Device T2 is based on Metal Oxide Varistors. 

Such a design provides a very low response time. 

Surge Protective Devices are designed to protect against transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure. 

However, lightning and utility power anomalies only account for 20% of transient surges. The remaining 80% of surge activity is produced internally. 

Although these surges may be smaller in magnitude, they occur more frequently and with continuous exposure can degrade sensitive electronic equipment within the facility.
