UNBALANCE, NVR, MANUAL-RESET & TEST)
1. The 3 phase load currents are displayed in sequence.
2. Possible setting with volume knob.
(overcurrent, current signal output, delay time, operating
time)
3. High reliability.
4. Combined type of Ammeter, OCR and Current Transducer.
5. Every trip is identified by LED on the screen.
6. DIP switches enable Fail-safe and phase reverse protection.
Usage
Overload protection for motor and other load.
Overload, Phase Loss, Phase Reverse and Phase
Unbalance protections for power distribution.
Ordering method
Caution
Check the preset values of current, range(4бн20mA), delay time
and operating time before starting, and check the operating
conditions of operating-relay(O.L) then.
Confirm the connection cable between Display and P-05/60
(Converter).
When install, the serial No. of units(converter and display
