K7L-AT50 User's Manual ()

Detect abnormal voltages applies to equipment to,
protect against equipment failure.
Monitor for overvoltages and undervoltages,
simultaneously with one Relay.
Monitor AC or DC voltages with one Relay.
Settings for the operating value, hysteresis, and operating time.
Width of 17.5 mm to reduce space required in panels K7L-AT50 User's Manual.
Push-In Plus Terminal that reduce wiring work.
The use of cage clamps enables wiring with bare stranded wires K7L-AT50
Double-insertion holes for crossover wiring (all terminals).
UL listed for easy shipping to North America.
Models added with transistor outputs for superior contact reliability. Setting range: 10 to 100 A AC, 20 to 200 A AC.
Power supply voltage: 24 VAC/DC K7L-AT50 User's Manual.
Ideal for Current Monitoring for.
Industrial Facilities and Equipment.
Monitor for overcurrents and undercurrents simultaneously.
Separate settings and outputs supported for overcurrents and undercurrents.
Use commercially available CTs (CT current on secondary,
side: 0 to 1 A or 0 to 5 A).
Manual resetting and automatically resetting supported by one Relay.
Startup lock and operating time can be set separately K7L-AT50 User's Manual.
Two sets of SPDT output contacts, 5 A at 250 VAC (resistive load).
Output status can be monitored using LED indicator.
Inputs are isolated from the power supply. Time specification: Instantaneous type.
Current setting range: 2 to 8 A.
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 indiccated from the start of operation K7L-AT50 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-AT50 Manual. Error will occur in the operating,
values of the overload elements. It is recommended to test operation,
before using the K2CM.
