Dual stage Track Arrester, 0-30 VDC (0-24 VAC), 15 ampere load current, with multiple fail safe open mechanisms, indicating fuse, test terminal. Mount on standard AAR 2 3/8” terminal binding posts for equipment and ground; with ring terminal lead 6.4” long (connect to line). For installation on each line (equalizer not required nor desired).

Performance :

Rating 40 KA, 8/20 µs (extreme maximum 75 KA) ; 5 KA, 10/1000 µs. Let-through energy (voltage and current) insignificant to cause damage to equipment. Fail safe operates 100% of time even with destruction of the arrester. The equipment avoids damage.

At 1000 amperes, 10/1000 µs the let-through voltage momentarily measures 130V for very short (microseconds) duration and drops to 30V for the balance of the surge current flow. The performance is same on either polarity of the surge.

Multiple fail safe open mechanisms provide redundancy in protection :
  1. Fail safe fuse (indicating type)
  2. Fail safe spring-loaded contact to semiconductor
  3. Fail safe gas tube braid to ground
  4. Fail safe spring-loaded gas tube contact to ground
  5. Fail safe open of the semiconductor to ground (shatter).

Vibration and shock per AAR Manual Part 11.5.1
Temperature range -55o to +75o C.
Manufactured in U.S.A.
ISO 9001 certification.
