Schneider three-phase differential switch without neutral

tableIn this Opportunity in Differential Switches, we will talk about the installation of three-phase differentials without neutral.

Use of Schneider RCDs in three-phase networks without neutral

 

To maintain the correct functioning of the differential standard IDs in all its aspects, when they are used in three-phase networks without neutral, the following connections must be taken into account.

 

Case 1. Network without neutral with 220 to 240 V AC between phases.

Case 1. Network without neutral with 220 to 240 V AC between phases.

If these connections are not followed exactly, the ID test button will be inactive, it must be pressed at least once a month, to ensure correct operation of the device when it has to trip before a real leakage current. As a rule. UNE EN 61008 it is mandatory that the test button works.

 

Case 2, network without neutral with 380 to 415 v AC

If the resistance indicated here is not used at the output of the differential, but only a jumper with cable, we run the risk of destroying the internal test resistance of the differential in the ortho term and, furthermore, when pressing the test button, a current will flow of defect superior to the one admitted by the norm.

There are also special AC class IDs, for 400V three-phase installations without neutral, which, as you can see on this page, is necessary for standard 4P differentials used in 400V lines between phases without neutral.

You can follow the same document for the three-phase connection without neutral.
>> If you are using the Acti9 RCCB range, you don’t need to add the resistor with iID Acti9 RCCB. You can directly connect phase 3 in 3 poles of RCCB (without neutral).

>> If you are using the Multi9 RCCB ID range we need to add a resistor with specific resistance values ​​to meet 380-415V. See attached sheet for connection and resistance values ​​used with RCCB multi9 range.
The devices have a torus that is activated by the unbalance of currents and trips.
The torus does not care if there are 2 or 3 or 4 lines connected as far as the out of balance current is concerned.
If there are 3 phases + N, then all phases and N conductors will vectorize the sum to zero, unless there is an out of balance current = trip if it exceeds the threshold.
If there are 3 phases and there is no N conductor then exactly the same applies = sum of the 3 currents = zero or you have a trip condition if the unbalance current is greater than the threshold.
We can get by without having an N conductor connected to the RCCB as shown below, because the test button creates a resistive load off the toroid at rated voltage to test the device.

Price of Schneier Three-Phase Differential Switches Without Neutral

Here you will find the best prices on the market since combined with the quality you will be able to acquire a totally professional durable product.

When looking for the right type of switch for what you need you will notice that we have a catalog full of all the products you need.

Why do you need to install schneider three-phase non-neutral differential switches

The specific operation that these devices present are very useful. It is impossible to think of a home or company that does not have these devices installed, since they would always be at the expense of damage to electronic devices without proper protection.

Characteristic of shcneider Three-Phase No Neutral RCCBs

The three-phase differential switch without neutral is a special electromechanical switch that, thanks to its internal devices, has the ability to detect the difference between the current absorbed by a consumer device and the return current. When this difference exceeds a value (30 mA), the device interrupts the circuit, cutting off the current supply to the entire installation.

The Three-Phase Differential Switch without Neutral is an electromechanical device, that is, its operation involves both electrical and mechanical energy, which is used as an automatic protection system.

This is installed in any electrical installation that has contact with people and its purpose is to protect people from any electrocution they may suffer.

How a shcneider Three-Phase No Neutral Differential switch works

To understand how a Three-Phase Differential Switch without Neutral works, you must first know how an electrical circuit works. If we have a circuit where a current intensity enters, it runs through different loads that can be the electrical elements of the home, the intensity of the electrical current that leaves the circuit is the same as that which entered.

Parts of a shcneider Three-Phase No Neutral RCCB

The oroid part: Central core of the phase, neutral and residual current coils.
Phase coil: It is the coil through which the incoming current passes to the home to generate the first magnetic field.
Neutral coil: It is where the outgoing current of the home circulates to generate the magnetic field that is equal to that generated by the phase
coil. Residual current coil: It is the coil that generates current in the event of a magnetic field. This residual current is the one that warns that there is a difference between the incoming current and the outgoing current.
Solenoid:It contains a coil through which the residual current passes. If this current exists, it means that the magnetic fields were not canceled, so the input current is different from the output current. This residual current generates a magnetic field that attracts the side of the solenoid, generating a movement that causes the circuit to open.
