EOCR-PMZ



Main Features

- The current system automatically displays 3-phase current and leakage current in circulation every 5 seconds
- Can be switched from auto circulation display mode to manual circulation mode with the touch of a button,
  allowing focused display on a certain element (one specific phase out of 3 phases or leakage current) 
- Contains the overcurrent/undercurrent/earth fault/current signal output function in a single EOCR
- Wide range of use: 0.1-3600A - wide range: 0.5-60A; for 5 holes: 0.1-2.0A; with the use of an external CT: 1-3600A
- Easily identifiable characters and numbers displaying trip causes
- The last trip causes are remembered up to the 3 most recent trip causes and the current one at the time of the trip, and checks the operation even during the recovery of electricity after a power outage
- Includes a timer function for checking total operation time and to provide a reminder of maintenance tasks, such as bearing replacement
- Has a bar graph that helps the manager to set the current level conveniently and to check the motor load factor 
- Has a transducer function (4-20mA current signal output) for easy and focused management
- For the current operation characteristics, select from Definite, Inverse, and Thermal Inverse
- Earth fault Oeakage) current detection: zero-phase current detection method 
- For the arth fault current operation characteristic, apply either Definite or Inverse
- Overcurrent Protection Characteristics
- Thermal Memory Protection ("th"): When Inverse is applied, the cumulative calculation value of the heat generated during the motor's operation is remembered to be protected directly by the hot curve instead of the cold curve. (Automatically resets 20 minutes after the motor stops) 
- Non-thermal Memory Protection ("In"): When Inverse is applied, it is protected by the cold curve if the motor has started, and by the hot curve during normal operation
- Removable EOCR allows its use in the terminal type or the hole type (removable terminal strip)
