Schneider Easergy P3M30 and P3M32 Motor protection relay
Description
The Schneider P3M30 Motor Protection Relay has a modular design and it can be optimized to almost all types of motor applications in low and medium voltage distribution systems.
Main characteristic and options
• The relay has all the necessary motor and feeder protection for industrial power distribution networks.
• The relay has an optional interface for connecting four arc flash point sensors.
• The relay has optional arc flash communications and high speed outputs to allow for simple arc flash system configuration.
• Two alternative display options
◦ 128 x 128 LCD matrix
◦ 128 x 128 LCD matrix detachable
• Power quality measurements and disturbance recorder enable capture of transients
• Wide range of communication protocols, for example:
◦ Modbus TCP/IP
◦ Profibus
◦ IEC61850
The following options depend on the order code:
• power supply options
• earth fault overcurrent input sensitivity
• number of digital inputs
• number of trip contacts
• integrated arc-options (point sensors)
• various possibilities with communication interfaces:
◦ high-speed outputs
◦ simple arc flash system communications (BIO)
◦ fiber loop
• front panel protection of IP54
Protection functions of Schneider P3M30 Motor Protection Relay
• Universal, adaptive protection functions for user-configurable applications like
feeder, motor and voltage protection from basic non-directional to directional
overcurrent protection and thermal overload
• Neutral voltage displacement, overvoltage and frequency protection including
synchrocheck for two breakers
2 Product introduction Motor protection relay
