Rack Mount 100 Pair MDF Terminal Block , Grey / Blue Main Distribution Frame

Main Distribution Frame constitute by the frame body, connection block, test module, alarm systems, test equipment, protection unit and so on, MDF is use to connection with the switch and the user cable, patch cord, over current, over voltage protection and alarm test function, the implementation of YD/T694-2004 standard products.

Features:

1. All aluminum alloy frame, rigid, elegant appearance, a variety of cable connecting all with Built-in card access methods, safe and reliable.

2. There are many dimensions, structure for the use of protection unit and connection block to meet the new, update, modification, maintenance needs.

3. With four-grade alarm, can use access control, security and other system monitoring the implementation of centralized control or centralized alarm remote interfaces.

4. Contact reed plated with gold or bright tin, flame retardant engineering plastic used. Has a good over-voltage protection and over-current failure to protect.

5. The frame has perfect grounding system.
