Product Description

We are famous in the market for providing Motor Protector. Our offered Motor Protector is useful for protection of 3-phase AC induction motors against various hazards. This protector has unique advantages which help in eliminating use of a thermal or bimetal relay for motor protection. Our provided motor protector is available with various features such as fixed or adjustable setting for under or over voltage, current , load, fixed or adjustable trip delays,fixed or adjustable unbalance settings, resetting automatic or manual. 

Specifications

  • motor protector : overload, over current, phase failure, over voltage etc. 
  • measure volt, amp, watt, kwh 
  • Modbus/Profibus

Features:

  • Use module framework. Several modules can be selected flexibly.
  • PMAC802 provides 12 protection functions such as start overtime protection, overload protection, overcurrent protection, phase failure protection, current unbalance protection, earth fault/leakage current protection, short circuit protection, underload protection, external fault protection, overvoltage protection, undervoltage protection, under power protection, phase sequence error protection, EEx e overload protection, temperature (PTC/NTC) protection, analog input protection.
  • Provides measurements of three phases current, three phase /phase voltage, zero phase sequence current, active power, reactive power, power factor, frequency, and active energy measurements.
  • Provides protection, direct starter, reversing direct starter, star/delta starter, and autotransformer starter etc motor starting control modes.
  • Main module provides 9 DIs for start, stop and reset etc. signals input. If more DIs are needed, an extended digital module can be selected. Some of the DIs are programmable.
  • Main module provides 5 DOs to meet varies of starting control modes and protection action. If more DOs are needed, an extended digital module can be selected. Some of the DOs are programmable.
  • Provides 4~20mA analog output for DCS.
  • Through an extended analog module, 2 analog input or 1 analog and 1 hot resistance input can be added.
  • Small size and compact configuration.
  • Easy installation. Proper for 35mm DIN rail.
