8 Insulation resistance

Relay’s every electric terminals are connected together. To the non-electrification metallicoutside part

or shell, its insulated resistance is less than 300MΩ measured by tramegger with opening voltage is 500V.

9 Medium intensity

Relay’s every electric terminals are connected together. And it can endure a 2000Vand 50Hz AC

voltage(virtual value) to the non-electrification metallic outside partor shell. There is no insulated breakdown

or flashover phenomenon

10 Anti-disturb capability Relay’s anti-disturb is accord with DL478-92 (<<Static Relay Protection and Security Auto-device currency Tech>>)
