25Hz Traction Rail Breaker

Product Description

PEECO's 25Hz Traction Rail Breakers are a unique design developed for the rail industry by Philadelphia Electrical Equipment Company for traction rail breaker applications. From the NEMA 3R enclosure down to the stainless steel bolts, every component and detail  of the 25Hz Traction Rail Breaker has been designed to exceed the standards and specifications of the rail industry.

PEECO's Traction Rail Breaker features well known vacuum breaker technology in conjunction with high ampacity insulated bus and industry proven high voltage bushings. PEECO's Traction Rail Breakers are tested and approved by KEMA™ per IEEE STD C37.09. PEECO's Traction Rail Breakers are certified for:

  • 12kV, single phase, 25 Hz
  • Continuous current of 1500 amps at 25 Hz
  • Interrupting capacity of 50kA
  • Both single & two pole rated for 125kV B.I.L.

Traction Rail Breaker Use

PEECO teamed up with SEPTA for an extensive breaker & control upgrade for multiple locations they operate in the Philadelphia area. Because of our unique design which allowed for the most efficient application use, SEPTA  chose to implement PEECO's cutting edge Traction Rail Breaker technology for the job. Below are a few pictures of our Traction Rail Breakers and the Traction Rail Breaker used for our SEPTA project.
