1-Phase Transition (By-Pass) Device
Ref. SS 428 91 01, EN 61230
The device is for use on underground rails at rail joints to ensure the earthing connection remains unbroken.
Earth clamps are made of hardened aluminium and equipped with contact plates of nickel-plated copper. Other parts
are of stainless steel. The clamp JK 361 has an integrated tool for cleaning the base of the rail. The clamps are equipped
with 1/2″ connection pins for tightening with e.g. ratchet wrench BV 5217. The earthing cable, made of highly flexible
ESTPR-insulated copper strands, has sealed cable connections, which prevent humidity from penetrating the cable. The
earthing cable is connected to the clamp with a cable lug. The clamps are equipped with stainless steel spring washers,
which give a constant contact pressure. The earth clamps are connected to the base of the rail, which allows rail vehicles to pass.
