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

Operating voltage: 200/220/240 VAC.
Resetting method: Manual.
Solid-state Relay Enables Choice of Three.
Operating Functions (Overcurrent, Open,
phase, and Reverse-phase).
Protects 3-phase induction motors and their loads from damage.
Selection and combination of operating functions from overcur,
rent, open-phase, and reverse-phase.
Circuit and output relay operation can be checked by just operat,
ing the test button.
The set time value can be checked easily because operation time,
is indicated from the start of operation.
Space-saving, integrated construction.
Note: If the K2CM is used with an inverter, the operating conditions will,
depend on the load wiring length, inverter carrier frequency, basic,
frequency, and load conditions. Error will occur in the operating,
values of the overload elements. It is recommended to test operation,
before using the K2CM.
