1.The Protector Block with capacity of 100 line-pairs is composed by
10 pieces of 10 line-pairs module and is adopted for double-sided and
single-sided MDF. Outside-cable wire via the left-side distribution
hook and is terminated on the back. Jump wire enters wire slot via the
right-side distribution hook and is terminated in the front.
2.Maintenance operators may get more work space because of the blocks
can rotate up to 90 degree to fit different working habits.
3.Torsional Clamping Reed is applied for terminating wire, so the
connection is reliable. Cable terminal is single-slot, but jumping
terminal is double-slot, it could clamp two wires.
4.In the left-side cover plate the alarm-signaling connective wires are mounted.
The row (every 10 line-pairs) alarm-signaling indicators are
mounted in the front.
5.All plastic parts are made by fire-resistant material.
