Ideal for 3-phase voltage asymmetry.
monitoring for industrial facilities and equipment.
Monitor voltage asymmetry, phase sequence, and phase loss,
for three-phase 3-wire or 4-wire power supplies with just one Unit K3HB-RPB Communications Manual.
Switch setting for 3-phase 3-wire or 3-phase 4-wire power supply K3HB-RPB
One SPDT output relay, 6 A at 250 VAC (resistive load).
World-wide power specifications supported by one Unit (switchable).
Relay status can be monitored using LED indicator. Type: Medium-sensitivity models.
Sensed current: 500 mA/1,000 mA(switchable).
Type: Delayed models.
Operating time: 0 K3HB-RPB Communications Manual. 3/0.8 s (switchable).
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.
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 K3HB-RPB Communications Manual.
The through-type ZCTs are equipped with test terminals,
allowing operation tests for Ground Fault Relays to be performed withease. Ideal for current monitoring for,
industrial facilities and equipment.
Monitor for overcurrents or undercurrents.
Manual resetting and automatically resetting supported by one Relay.
Startup lock and operating time can be set separately.
One SPDT output relay, 6 A at 250 VAC (resistive load).
Output relay can be switched between normally open and,
normally closed.
Process control signal (4 to 20 mA) and commercial CT input,
(0 to 1 A or 0 to 5 A) supported.
Output status can be monitored using LED indicator.
Inputs are isolated from the power supply. Models: UVR+OVR.
Protection of distributed power supply connection to power system,
The relay is smaller, and the protection unit is more enriched.
Waste heat generation system improve the comprehensive energy efficiency and the use of natural,
Energy of wind power generation, the spread of power is becoming more and more popular.
This relay is used to detect the internal fault of the user in the distributed power supply,
Power line accident of distributed power supply and relay protection system.
The relay can be meet in Japan (system connected instant points specified in the standard model),
Function, can be through more than 20 kinds of products to establish the best protection system.
Can also correspond to the generator and the electric side / internnal tributaries K3HB-RPB Manual.
Unit with 2 relay elements.
In each unit, the variable action time circuit is hidden, so that the coordination design is more convenient.
All aircraft equipped with a locking relay terminal.
DSR can correctly determiine the direction of the sudden drop in the voltage to 0 of the short-circuit accident K3HB-RPB Manual.
2 stage cross terminal stand with cover with convenient wiring.
