Explore MoreOld relays miss directional logic, struggle with SEF, misread breaker health, and fall short in mesh or ring systems. That leads to slow clears, mis-ops, and long recovery times.
P841 delivers comprehensive phase and earth-fault protection with directional logic, REF, SEF, thermal models, and voltage/frequency supervision. It controls one or two breakers, handles auto-reclose with mesh-corner intelligence, and performs synchro-check before every close. With PSL logic, breaker condition monitoring, and strong communication protocols, P841 becomes the brain of any feeder bay.
Every feeder stays visible, protected, and ready.
Multiple overcurrent stages with directional logic for every network type.
SEF and REF catch low-level internal faults that others miss.
Tracks wear, operating times, broken current and health.
Single/three-pole AR with skip-shot and leader/follower setups.
Safe synchronism, safe closing, stable network support.
PSL logic for interlocking, tripping, transfer schemes and workflows.
Modular hardware. Tough design. Modern comms.
Built for every layout. Trusted in every bay.
Wherever feeders run, P841 protects.
