Overview of EOCR-i3MZ

✔32-bit MCU+True RMS measurement, accuracy ± 1%

✔Protection functions: overload (OC), underload (UC), phase loss (PL), reverse phase (RP), imbalance (Ub), startup stall (Sc), running stall (JA), leakage (lg)

✔High frequency component filtering - the function of measuring and removing high-frequency components and pulse noise components of leakage current

✔Action time characteristics: timed limit, inverse time limit, thermal accumulation inverse time limit

✔THD total harmonic distortion monitoring: real-time monitoring of three-phase, adjustable alarm threshold

✔Modbus RTU/RS-485 2400-38 400 bps remote communication

✔Display: Bar load graph+5-digit seven segment digital tube LED

Three phase current automatic rotation display/manual locking of a certain phase display (manual locking function)

✔Operation/Fault Records:

• Reasons for tripping and current records of the last 3 faults

Accumulated running time and timeout alarm records

• Limit the number of startup records

✔Fail Safe mode: independent start stop function (safe mode)

✔Password protection function: Three digit password to prevent accidental operation; Long term shutdown can restore factory settings

✔Reset mode: manual, automatic, power-off, remote communication

✔Structural selection: Terminal T, Bottom hole H, Window W

✔Three phase/single-phase mode Menu switchable

✔Compliance and certification: UL, CCC, compliant with EU RoHS
