<p>A failsafe mechanism for protecting telecommunication equipment, having a tip (26) and ring (28), by shunting a sustained overvoltage or excessive current surge to ground, includes a failsafe clip (36), a diode bridge (11), and a trigger unit (12). The trigger unit is configured to bias the second end of the failsafe clip in the normally open position, but releases the failsafe clip when either the sustained overvoltage causes the module components to become excessively hot, or the current surge is high enough to cause a fusible link (34) to part, whereby the failsafe clip shunts all current to the ground.</p> |
