Type: CWMDF112A-P
Product Name: PROTECTOR BLOCK
|
Product Description ...
1?Protection connection block is mounted on the vertical side of MDF, which is used for termination between external line cable and jumper wire, it can protect the MDF against over voltage and over current,
2?Perfect and reliable over-voltage and over-current protection with sound and light alarm, and self resulming fail protection; (With Protector unit)
3?it is designed in such structure: the line side and the jumper wire side is disconnected before the protector is inserted into the protection connection block, they will be connected after inserting the protector,
4?when the line side suffer danger, only pull out the protector, the exchange side will be disconnected with the outside line,
5?The performance of anti-burn: PPT(UL94V-0) or anti-burn ABS(UL94V-0), combustibility achieved GB/T 5169.7-1985 standard
6?Each protection block has termination capacity of 100 pairs and consist of vertical module, 100 alarm plug, back-mounting frame etc. both the outside line and the jumper wire side have the wiring board.
