详情

PMAC**1 Motor Protection Relay with Following Features: 

1>>. Use module framework. Several modules can be selected flexibly.

2>>. PMAC**0 Low Voltage Motor Protection Circuit Breakerprovides *2 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 protection.

3>>. 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.

4>>. Provides protection, direct starter, reversing direct starter, star/delta starter, and autotransformer starter etc motor starting control modes. 

5>>. Main module provides 9 DIs for start, stop and reset etc. signals . If more DIs are needed, an extended digital module can be selected. Some of the DIs are programmable.

6>>. 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.

7>>. Provides 4~*0mA analog output for DCS.

8>>. Through an extended analog module, 2 analog or 1 analog and 1 hot resistance can be added.

9>>. Small size and compact configuration.

*0>>. Easy installation. Proper for *5mm DIN rail.
