The P50 Agile P153 protection relay is a compact offering from GE's P50 Agile series serving the distribution and industrial markets.

The compact P153 relays are the ideal choice for primary or back up protection and monitoring of feeders deployed in medium and low voltage applications. It offers non directional overcurrent and earth fault protection, with its functions designed to cover a wide range of applications in the protection of cables and overhead lines deployed in industrial installations, public distribution networks, and substations.

The P153 relays offer supervision features such as measurement, monitoring and recording functions. Communication protocols available are site selectable for transmitting relay data to a supervisory control system via communication networks. The operator interface allows reading of measured values and simple configuration of the relay. The setting software facilitates configuration and access to all the stored information for monitoring, maintenance and troubleshooting purposes. P153 relays are housed in a robust metal case suitable for panel mounting.

Key Benefits:

• Cost effective, compact size
• Measurement / protection / monitoring in one box
• Continuous self-diagnostics
• Advanced communication including front USB, user selectable communication protocols
• Simple configuration and easy setup from front HMI

The Multilin™ 350 is a member of the Multilin 3 Series protective relay platform and has been designed for the protection, control and management of feeders or related applications as a primary or backup protection device.
