Voltage and current display relay is a microprocessor-based voltage monitoring device for sinale-phase AC networks to protect electrical equipment from surge voltage. The device analyzes the main voltage and displays its curent value on a digital indicator. Load is switched by electro magnetic relay. The user can set the current voltage value and delay time through the button.The value is stored in non-volatile memory. Aluminum wires and copper wires can be used for connection.

This automatic reactive power compensation controller.It is suitable for automatic regulation of capacitor compensation device in low voltage distribution system (hereinafter referred to as controller).It makes the power factor reach the user’s predetermined state, improves the utilization efficiency of the power transformer, reduces the line loss, and improves the voltage value of the power supply, so as to improve the economic and social benefits.

The AFDD9NL-40 series Arc Fault Detection Device are assembled from 18mm – wide double – pole leakage circuit breakers (RCBO) and arc – detection modules. The products have functions of short – circuit protection, over – current protection, over – voltage protection, leakage protection, and arc – fault protection.

The AFDD9NL-40 series Arc Fault Detection Device meet the performance requirements of the standard IEC62606 – 2013. The AFDD9NL-40 series is designed in particular for UK market.

AFD9-63 , a three phase four wire Arc Fault Detection Device (AFDD), designed to reduce the risk of electric fire, can effectively detects electric arc faults, disconnects the affected circuit and offers complete protection in residential,non-residential building, energy sources, industry and infrastrutures. Installation of AFDD is strongly recommended in location with sleeping accomodations, place with fire risks due to big quantity flammable materials, place with combustible building materials, place with irreplaceable goods and beyond.

The AFDD9-63 three – phase four – wire Arc Fault Detection Device is assembled from a miniature circuit breaker(MCB) and an arc – detection module. The AFDD9-63 Arc Fault Detection Device has functions of short – circuit protection, over – current protection, and arc – fault protection. It can simultaneously detect the A – phase, B – phase, and C – phase fault arcs in three – phase circuits, and can also detect the fault arcs between phases. When the Arc Fault Detection Device detects an arc fault in the circuit, it will immediately cut off the power supply to play a protective role.

The AFDD9LE-63Y series Arc Fault Detection Device are assembled by residual current circuit breakers (RCBO) and arc detection modules.The AFDD9LE-63Y Arc Fault Detection Device possess the functions of short-circuit protection, overload protection, residual current protection and arc-fault protection. They are suitable for being installed in branch circuits and can quickly cut off the circuits to play a protective role when overcurrent, short-circuit, leakage or arc-fault occurs in the branch circuits.
