Three-phase Phase-sequence Phase-loss.
Relay Using Voltage Detection Method K3MA-F-A2 PDF.
Fixed phase Asymmetry monitoring.
Prevents reverse motor rotation due to incorrect wiring.
Distinguishes between positive phases, reversed phases, and phase,
loss when power is turned ON.
Voltage detection method enables application for any load current K3MA-F-A2
One SPDT output relay, 6 A at 250 VAC (resistive load).
Output status can be monitored using LED indicator. Control supply voltage: 110 VAC; With voltage fluctuation compensation K3MA-F-A2 PDF.
Operating current: 8 to 20 A.
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 K3MA-F-A2 Manual.
Precisely singles out the burned element even if one heater el,
ement among several heater elements has been burned out K3MA-F-A2 PDF.
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 OMRON Communications Manual. Time specification: Inverse type.
Current setting range: 20 to 65 A.
Operating voltage: 200/220/240 VAC.
Resetting method: Automatic (See note.).
Solid-state Relay Enables Choice of Three.
Operating Functions (Overcurrent, Open,
phase, and Reverse-phase) OMRON Communications Manual.
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 operatiion OMRON Communications Manual K3MA-F-A2 Communications Manual.
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 K3MA-F-A2 Manual. Error will occur in the operating,
values of the overload elements. It is recommended to test operation,
before using the K2CM.
