Class C surge protection device is designed to protect against high-energy surges typically caused by indirect lightning strikes or large power surges from utility grid disturbances. These devices are commonly used to protect sensitive electronic equipment and systems, such as industrial machinery, data centers, and telecommunications equipment.
Class C surge protection devices are installed at the main electrical panel or distribution board to provide protection for the entire electrical system. They are designed to handle high surge currents and are often used in conjunction with Class B and Class A surge protection devices to provide comprehensive protection against all levels of surge events.
These devices typically employ a combination of metal oxide varistors (MOVs), gas discharge tubes, and other surge suppression components to divert and dissipate surge energy away from the protected equipment. They are also designed to provide visual indication of their status and may include remote monitoring and alarm capabilities.
Overall, Class C surge protection devices play a critical role in safeguarding electrical and electronic systems from the damaging effects of high-energy surges, ensuring the reliable operation and longevity of sensitive equipment.
