Leakage and analog output motor protector EOCR-PMZ

Leakage and analog output motor protector EOCR-PMZ

EOCR-PMZ is the new generation electronic motor protector product of Schneider EOCR. It is a split type leakage protector designed for distribution cabinets and the power grid industry. Its main protection functions include overcurrent, undercurrent, phase loss, reverse phase, locked rotor, current imbalance, leakage, etc. It also has a 4-20mA current output function,

Leakage and analog output motor protector EOCR-PMZProduct performance：

◆ Current indication function: Three phase current value and grounding current value are displayed in a 5-second cycle

◆ Switch from automatic loop display mode to manual mode through button operation, and display a fixed phase current value or grounding current value

◆ Overcurrent/Undercurrent/Grounding Fault/Analog Output of Current

◆ Wide current range: 0.1~3600A - Wide range: 0.5~60A; 5 turns: 0.1~2.0A; External CT: 1~3600A

◆ Fault code and current value display

◆ Record the causes and current values of the last three faults, even if the power supply is interrupted and restored, it can still be queried

◆ Built in timer function, used to query the total running time and prompt managers to maintain regularly, such as bearing replacement

The current amplitude bar indicator can help managers check the load factor of the motor

◆ Equipped with sensor function (4-20mA current analog output) for centralized management

◆ Overcurrent time characteristic curve, with definite time/inverse time/overheat inverse time selectable

Grounding fault current detection: zero sequence current detection method

The definite time/inverse time limit also applies to the working characteristics of grounding current faults

◆ For terminal types, they can be disassembled and installed in a through type for combination

EOCR is the abbreviation for Electronic Over Current Relay, which originated from SAMWHA EOCR Ltd, a company founded in 1981

This company originated from Sanhe SAMWHA Co., Ltd. in South Korea and is a manufacturer of electronic motor protectors. It specializes in producing overcurrent relays, undercurrent relays, motor protectors, voltage protection relays, DC current protectors, voltage protection relays, surge protection relays, leakage protection relays, etc. The initiator is Dr. Jin Renxi (currently the Korean executive officer of Schneider Electric Group) who studied in the United States.
