WebThe overcurrent relay SPAJ 131 C is designed to be used for two-stage phase overcurrent protection of distribution feeders, large low-voltage motors, high-voltage motors, medium-sized and large generators and power transformers. The relay can be used both as main protection relay and back-up protection relay. WebOvercurrent protection is generally a protection against short circuit where excessive current starts to flow in the circuit which leads to damage the connected equipment. Fuses, circuit breakers, overcurrent relays, current limiters, temperature sensors and solid state power switches are used against overcurrent protection devices.
