ZE4125 Demonstration Panel for the Study of the Protection Devices for Safety and Continutity of Electric Power Supply


This panel can be used by teachers for their lessons and by students for an easy learning and testing on actual protection electric devices that ensure the safety of both people and system, besides the continuity and quality of electric power to power consuming devices. The panel supplies means for verifying the rule of art and the relevant technical standards.

The various electrical devices installed, connected partially with each other and with safety terminals, become operating with very simple and fast operations, offering the possibility of creating, modifying and checking the safety devices of the installation.

The panel is made of insulating material and it represents thesupport for the necessary devices for carrying out the testing Programme.

The apparatuses are represented on the panel with their standardized international symbols and, when necessary, test points correspond to standardized educational terminals with high protection degree against accidental contacts.


This panel includes some innovatory electric devices for the protection of people and of installations against the effects of electric current that ensure continuity of power availability, besides safety of people. The fi eld of application of these devices includes both civil installations and those of business and/or production (craft-industrial) sectors.

Main topics dealt with:

Protection by earthing
Protection by differential circuit breaker, automatic reset
Protection by differential circuit breaker, emergency stop in positive safety
Protection by differential circuit breaker, double sensitivity
Switch for reducing electric fi elds (bio switch)
Coordination of antijamming protection devices
(overvoltage limiter, SPD) at several levels
Uninterruptible Power Supply (UPS) for single-phase lines
These devices can be used and studied one by one, or in
coordination with each other.


Framework is made of sheet steel chemically treated and painted with several coats of epoxy varnish; its base is provided with rubber feet and it can be positioned on a
working top.

All the necessary electric components for the correct power supply of circuits are included in the panel.
Main components installed:

1 differential circuit breaker; Idn = 30 mA; type A; with devices of automatic reset
1 magnetothermal differential circuit breaker; In = 1 A; curve [C]; Idn = 0.3 A; type AC; with emergency stop circuit in positive safety 1 power line of 230 Vac -1 A for powering auxiliary devices
1 magnetothermal differential circuit breaker of double sensitivity; In = 10 A; curve [C]; Idn = 30/200 mA; type AC
1 switch for reducing electric fi elds (bio switch)
3 antijamming protection devices (overvoltage limiters, SPD with current of 15 – 40 – 65 kA)
1 Uninterruptible Power Supply (UPS) for single-phase with output rated current of 500 VA at 230 V
1 single-phase isolation transformer of 230 / 230 V 500 VA
1 simulator of user earth resistance of 1, 2, 20, 200 Ω
1 simulator of earth fault adjustable between 5 and 35 mA
1 simulator of earth fault adjustable between 100 and 300 mA
Dimensions of demonstration panel: 800 x 600 mm
Dimensions of framework: 840 x 450 x 680 mm
Net weight: 40 kg

1 single-phase power cord with UNEL plug
1 set of cables and jumpers with safety plugs (Ø 4 mm)
230 V / PE 50-60 Hz
Max. absorption: 500 VA
