Switch setting for 3-phase 3-wire or 3-phase 4-wire power supply K7L-UD
One SPDT output relay, 5 A at 250 VAC (resistive load).
World-wide power specifications supported by one Unit (switchable).
Relay status can be monitored using LED indicator K7L-UD PDF. Type: High-sensitivity models.
Sensed current: 30 mA (fixed).
Type: High-speed models.
Operating time: Less than 0.1 s.
Economical, Compact, High-performance,
DIN 48 × 48-mm Ground Fault Relay for Low,
Voltages.
Performs continuous monitoring and detection of ground faults,,
in low-voltage circuits due to the deterioration of insulation in,
electrical devices K7L-UD PDF K7L-UD Manual.
Higher reliability ensured with improved resistance to high-fre,
quency noise when used for inverter loads.
Ground Fault Relays and through-type ZCTs (zero-phase current,
transformers) are mutually compatible.
The through-type ZCTs are equipped with test terminals,
allowing operation tests for Ground Fault Relays to be performed withease OMRON Communications Manual. Time specification: Instantaneous type.
Current setting range: 8 to 26 A.
Operating voltage: 100/110/120 VAC.
Resetting method: Manual.
Solid-state Relay Enables Choice of Three OMRON Communications Manual.
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 OMRON Communications Manual.
The set time value can be checked easily because operation time,
is inddicated from the start of operation K7L-UD 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 K7L-UD Manual. Error will occur in the operating,
values of the overload elements. It is recommended to test operation,
before using the K2CM.
