Built for Safety and Performance
Designed with a neutral structure and permanent magnet, these relays only activate with the correct voltage polarity. A leakage strip between the coils and armature ensures controlled operation.
Built to perform under tough conditions, they’re ideal for DC high-percentage release track circuits – up to 20,000 feet long. With a low 0.5-ohm resistance (coils in parallel), they provide fast response and high shunting sensitivity, even in poor ballast.
Available in B1 and B2 sizes, with two B1 relays fitting in the same space as one B2, they offer flexibility and strong protection against foreign currents.
