| EOCR-SS Overview ✔ Economical electronic overcurrent protection relay✔ Built-in MCU microprocessor, small size ✔ Built-in current transformer, support threading measurement, more convenient installation ✔ 0.5~60A protection range; time-limited protection, tripping time can be adjusted at will ✔ Start time and overcurrent action time are designed separately for accurate setting ✔ LED diode with different flashing frequencies indicates fault ✔ RESET button manual reset and power-off reset mode ✔ DIP switch sets power-off protection mode (N and R) ✔ Can be used for single-phase motor protection ✔ Can be installed on DIN rail (35mm) or screw fixed installation ✔ CUL, CE, CCC, RoHS certification |
EOCR-SS Applications
✔ Hoisting, HVAC, grinding, mixing and other occasions where stalling is prone to occur
✔ Applications such as fans and pumps where the startup time is too long
✔ Frequent startup or periodic loads such as transmission
EOCR-SS protection functions
✔ Overcurrent (O-Time)
✔ Phase loss (O-Time)
✔ Stalling (O-Time+D-Time)
