Overview
The EOCR-FEZ Schneider External ZCT Type Protector $r $nEOCR3EZ EOCR-FEZ Ground Leakage Protector not only monitors and protects against motor overload, phase loss, locked rotor, and current imbalance faults, but also monitors and protects the insulation and leakage conditions of the motor and its circuits. A B C three-phase and leakage current values are displayed cyclically, and the fault cause and fault current value can be displayed.
Product Details
EOCR-FEZ Schneider External ZCT Type Protector
The EOCRFEZ protector has been widely used due to its excellent product performance and cost-effectiveness, and has received high praise from users. In 2022, Schneider Electric upgraded the product to the ECOR3EZ-05AUH/05AUT/05CUH/05CUT model; Eight models, EOCRFEZ-80AUH/80AUT/80CUH/80CUT, are sold by Shanghai Hanshi Electric as agents! This product has protection functions for overcurrent, undercurrent, phase loss, locked rotor, reverse phase, phase imbalance, and leakage
Residual Current Device (RCD)Technically, the following requirements should be met:
The sensitivity of electric shock protection should be correct and reasonable, and the general starting current should be within the range of 15-30mA.
The action time of electric shock protection should generally not exceed 0.1 seconds.
3. The protector should be equipped with necessary monitoring equipment to prevent it from losing its protective function when the operating state changes. For example, for voltage type electric shock protectors, a neutral grounding device should be installed.
EOCR-FEZ Schneider External ZCT Type Protector
