Fast, Reliable, and AREMA-Compliant

These relays come in a wide range of coil resistances, contact layouts, and materials, and are available in both B1 and B2 sizes. The clear housing makes it easy for maintainers to see if the relay is picked up or released. For convenience, they mount directly to a plugboard, allowing for quick installation and testing.

All B-Series relays use the same wiring terminals, mounting hardware, and tools, making them easy to integrate and maintain.
