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.

Brand Prok dv's Phase Three Phase Changeover Source Type Dual Source Display Type 2 Line,16 Character Back Lit LCD display Mounting Din Indication LED Indications for presence of EB & DG Degree Protection IP20 Dimension 143 x 158 x 136 mm Tolerance +/- 1 mm Material ABS Fire Retardant Plastic Indications LED Indication for Presence of EB & DG Conditional Shot Circuit Current 1 kA Features :
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.
