OMRON K2CM-Q1H Product information and technical parameters:
Brand: OMRON
Name: Motor Protective Relay
Model: K2CM-Q1H
Time specification: Instantaneous type.
Current setting range: 50 to 160 A.
Operating voltage: 100/110/120 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.

Functions: Phase sequence and phase loss monitoring.
Rated input voltage: 200 to 500 VAC.
Three-phase Phase-sequence Phase-loss.
Relay Using Voltage Detection Method.
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 OMRON K2CM-Q1H.
Voltage detection method enables application for any load current K2CM-Q1H
One SPDT output relay, 6 A at 250 VAC (resistive load).
Output status can be monitored using LED indicator. Water- and Environment-resistive FA.
Connectors Save Wiring and Maintenance Effort.
Compact FA connectors meet IP67 requirements and ensure a,
94V-0 fire retardant rating OMRON K2CM-Q1H.
A wide array of connectors makes a wiring system more modular,
simplifies maintenance, and reduces downtime.
Connectors with Cables and Connector Assemblies are available.
Three types of Connector Assembly: Crimping, soldering, and screw-on.
Connectors with Cables are UL certified.
Based on IEC61076-2-101 (IEC60947-5-2) and NECA 4202. Specifications: Connector with DC line not connected (Not for parallel operation) OMRON K2CM-Q1H.
Number of Connectors: 1 Connector.
Block-type Switch Mode Power Supply That.
Mounts to DIN Rail.
One model covers 30 to 120 W (12-V models).
One model covers 60 to 240 W (24-V models).
Easy creation of multi-power supply configurations with different,
output power supplies connected together (5-V, 12-V, and 24-Vmodels).
Improve power supply system reliability by creating N+1 redun,
dant systems (12-V and 24-V models).
RoHS-compliant.
Input conditions: 80 to 370 VDC supported for DC input too,
(EC Directives and safety standards are not applicable.)

Weight: Approx. 1150 g.
Comprehensive Lineup of Single,
Double, and Triple Axial Fans with,
Easy One-step Mounting.
Mounts in a square cutout and conceals the holle-cut to,
simplify installation work K2CM-Q1H.
Cover can be set to open either upward or downward for,
convenience in confined spaces.
Enhanced accessories (finger guard, filter, plug cord,
mounting screws).
Optional Replacement Filter and VVent Attachment K2CM-Q1H.
The lineup includes Single, Double, and Triple Box Fans,
with eight models with plastic blades and eight models with,
metal blades.
