| EUCR Overview ✔ Undercurrent protection ✔ Wide current setting range ✔ Operating current confirmation function ✔ Definite time overcurrent characteristic ✔ Manual (immediate)/remote (reset) ✔ Freely adjustable reset time or option to disable this function ✔ Strong environmental adaptability ✔ Ultra-low power consumption ✔ Only produces type R products (non-fail-safe) ✔ Undercurrent operation required when no current in the main circuit (with the NLT dip switch set to ON) |
EUCR Applications
✔ Prevent motor burnout of the water pump due to lack of water
✔ Monitor damage to heating rods in electric heating systems
EUCR Protection Features
✔ Low current (operates after U-Time)
