Heater Element Burnout Detector
K2CU
Accurate Detection of Heater Element
Burnout Regardless of Heater
Capacities
Accurately detects a burned heater element or
elements incorporated by a molding machine or
packing machine and outputs an alarm signal.
Precisely singles out the burned element even if
one heater element among several heater
elements has been burned out.
Applicable to small- to large-capacity heater
elements.
All K2CU-F large-capacity, built-in current trans-
former models work with both single-phase and
three-phase heaters.
Voltage fluctuation compensation function elimi-
nates false alarms due to variations in the supply
voltage.
