IFDM-WRDUHZ Schneider Communication Protector

IFDM-WRDUHZ Schneider Communication Protector

Shanghai Hanshi Electric Automation Equipment Co., Ltd. is the regional manager of Schneider EOCR motor protectors in China. The company has always been committed to promoting, selling, and providing technical services for the full range of Schneider EOCR (formerly known as Sanhe) electronic relays The products are widely used in many fields such as steel, petrochemicals, electricity, machinery, OEM, etc. Schneider EOCR products have the characteristics of exquisite design, reliable and accurate action, and comprehensive protection functions, and are deeply trusted by users.

Schneider IFDM Korea Sanhe EOC Motor ProtectorThe EOCR-IFDM intelligent split motor protector can be selected from three types based on the main circuit cable threading method: window type, through type, and terminal type. Due to its split installation feature, the display panel can be installed on the distribution panel.

Schneider IFDM Korea Sanhe EOC Motor Protector

◆ Built in MCU (microprocessor control unit)

Real time monitoring/high precision

◆ Protection functions: overcurrent, undercurrent, reverse, phase loss, stall, current imbalance

◆ Additional functions: power failure protection, pre alarm, accumulated running time, recording the cause and current of three faults and multiple reset modes to choose from

◆ Strengthen monitoring function: three-phase current cycle display&trip reason display

◆ Time limit/inverse time limit/overheat inverse time limit can be selected

The current amplitude bar can display the real-time operation status of the load

Communication method: Modbus RS-485

For split type products, even if not connected to PDM approval, it provides normal protection functions

IFDM-WRDUHZ Schneider Communication Protector

EOCR-IFDM-WRDUHZAndEOCR-IFDM-WRDUWZThese are two commonly used models in this series.

These two models are identical in terms of core functions, protection performance, and communication capabilities, both possessing:

• Comprehensive motor protection functions (overload, phase loss, locked rotor, current imbalance, etc.);

• Built in MCU for high-precision measurement (± 1%);

• Supports Modbus RTU (RS-485) remote communication;

• Split design for easy installation and wiring;

• 0.5~80A direct measurement range, expandable to 3600A.

TheyThe difference lies in the threading method of the main circuit cable‌：

• ‌WRDUHZH represents "Hole Type", where the cable needs to pass vertically through the protector body from top to bottom, suitable for control cabinet structures with upper and lower wiring.

• ‌WRDUWZW represents "Window Type", where the cable runs horizontally from front to back and is suitable for installation environments with front to back wiring.

Due to the diverse wiring methods in industrial sites, these two models are adapted to different distribution cabinet layouts and are therefore commonly used in practical applications. The selection is mainly based on the on-site cable routing and spatial layout.

In addition, this series is also commonEOCR-IFDM-WRDUTZ(Terminal type), suitable for low current or fixed wiring situations, but with a slightly lower frequency of use than the previous two.
