Trip and Lockout Relays (F86) – BF-3RP (Model) – BF-4RP (Model) – BJ-8RP (Model)

The Arteche F86 series Trip & Lockout Relays (BF-3RP, BF-4RP, BJ-8RP) are designed to safely isolate faulty equipment and ensure coordinated protection scheme operation. These high-speed, mechanically latching relays provide reliable control for breaker trip commands, interlocking, and lockout functions in substations. With multiple contact configurations, robust mechanical construction, and high dielectric strength, they ensure secure operation during fault events. The relays maintain their position even during power loss, guaranteeing lockout integrity. Compliance with IEC standards and long mechanical life make them ideal for modern protection systems.
