6 Contact capacity

Signal contact :30VDC 5A;250VAC 5A

Main contact: 250VAC COSФ=1.0 5A

250VDC making 5A

250VDC τ=5mS breaking 500W

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>>)
