The wide range of auxiliary input for both AC & DC
Independent contacts for both Under & Overvoltage
Self-reset & site selectable reset gap
Built-in fixed instantaneous Under & Overvoltage highest trip
User-friendly setting modes using keypads
Low power consumption
Tropicalized design using microcontroller & Ideal for industrial environment
Prok dv's make Digital microprocessor/microcontroller based Earth Leakage Relays (ELR) with Core Balance Current Transformer (CBCT / ZCT) are used to detect leakage currents in electrical power systems.
ELR transmits a signal to activate the trip coil of the MCCB/ACB/OCB/CONTACTOR in the event of earth leakage resulting in automatic isolation of the load. ELR have been widely used and accepted because of field adaptability and are economic.
Current ratings 1 Amps to 63Amps continuous duty when the load on EB/DG
While monitoring the Generator supply, it allows only a limited load and functions as Load limiter as per desired current (Factory set)
Whenever Load Current exceeds the present limit, power is automatically switched off and on automatically after 9 seconds and trips again if the overload still exists this cycle(3sec ON & 6sec OFF) is repeated every 9 sec, ACCL will enter into LOCKOUT mode after 5 ON & OFF cycles if overloading of DG still exists.
On resumption of EB mains, ACCL automatically changes from DG to EB and allows full current. ACCL comes out of LOCKOUT mode when EB resumes
The unit can be Reset manually by RESET switch
The ON/OFF cycles can be set according to customer requirements (optional)
If the unit has entered LOCKOUT mode due to OV/UV, the unit has to be reset manually.
