CHT1-B series surge protector (hereinafter referred to as SPD) is suitable for IT, TT, TN-C, TN-S, TN-C-S and other power supply systems of low voltage AC power distribution system, and protects against indirect lightning and direct lightning or other transient overvoltage surges. It is a Class II surge protector based on IEC61643-1:1998-02 standard. Class C surge protector. SPD has common mode (MC) and differential mode (MD) protection modes. The product complies with GB18802.1 and IEC61643-1 and other standards.
The response time of a DC SPD is also an important parameter. The shorter the response time, the faster the protector can start when a surge occurs, thus better protecting the equipment. The installation method and environmental conditions also need to be considered to ensure that the protector can operate stably in a specific working environment.
