Protection Unit

 

·Insulation Resistance:

 

Under normal ambient conditions, the insulation resistance, between any two independent contacts, and between any contact and metal parts should be grater than 100V (DC)

 

·Contact resistance between conductor and reed: ≤7 mΩ

·Breakdown DC voltage: UDC=190×260v

Impulse breakdown voltage Umax≤800V (1KV/s escalating rate)

Alarm and FS protection:

When a line or b line encountering over-voltage meanwhile its current to earth reaches up to 2.5A (virtual value), the protector will alarm within 5×15 seconds, at the same time a line and b line will be grounded.

·Resistance under normal temperature: (at 25 2)

Resistance between a line and b line under normal temperature: initial value≤22 mΩ

Resistance difference between a line and b line: initial value≤2 mΩ

·Unresponsive current: 100mA, (test voltage: 60(DC), Environmental temperature 40°C)

·Plastic fireproof capability: approved National Standard: GB/T5169.71985.
