Feeder protection relay
PMAC813 Zhuhai Pilot Electronics

PMAC813 Low Voltage Feeder Protection Device is suit for outgoing feeder at 380Vac rated voltage or below. It is designed for monitoring and protecting the status of outgoing feeder. The device implement on-line detection in the circuit and displays real-time running status. When expection occurs in the circuit, the device will selectively take protective action according to the set value, meanwhile, it records fault information for tracking the cause of fault. Via the isolated communication bus, the device can instantly upload the data to monitoring system, then form an integrated and automotive control system for providing great guarantee of security, stability and cost-effective of power supply.

Features:

Measure three phase current, neutral current, line voltage, power, frequency, power factor, energy etc.
Provide optional self-own current transformers or protective current transformers.
Provide 7 kind of standard protection and 1 kind of optional leakage protection.
Provide standard 4 DI and 3 DO, optional one 4~20mA analog output and one leakage current input
Provide one RS485 communication port which support Modbus-RTU protocol
10 event logs of fault trip
Large LCD screen, operated buttons for data inquiry and parameter setting
All-in-one panel mounting
