Will the new web server be available for all models who have the current webserver via firmware upgrade?

Yes!

Why are switch mode power supplies used?

Switch mode power supplies are smaller, lighter and more efficient than the conventional power supplies that used large and heavy transformers.

RCBO /RCB use - do we need both?

RCCBs and RCBOs are both part of the same family, RCD’s - devices that performs residual current protection (earth leakage). The RCBO combines this with overcurrent protection, it’s a circuit breaker and residual current breaker in one single unit. The RCCB is a residual current circuit breaker only, it is used together with circuit breakers.
K
L

Neutral disconnect protection - why?

Put simply, the neutral connection is essential for maintaining the 230V voltage between live and neutral. It can be seen as an “anchor point”. If the neutral connection is lost (or weak), the live to neutral voltage will instantly drift away, some to a higher voltage, some to a lower voltage. Worst case, two thirds of all connected loads will be subjected to destructive overvoltage and stop functioning. This is not something that circuit breakers or RCDs can protect against and modern equipment being powered (lights, video screens etc) have no protection against it either.

Why switch both L and N on load circuits?

Our RCBOs and our 3-phase MCBs (circuit breakers) also break the neutral connection when tripped or manually switched off. This is a legal requirement in many countries and since our products are designed to be used globally, we fit this as standard.

Can you reset a breaker from the remote software?

No.

How often do I have to service and test StageSmarts products?

Service and testing intervals can vary depending on local regulations. We recommend checking the specific requirements in your country or region to ensure compliance. Always follow national safety standards and guidelines for electrical equipment.

K
L

Why have variable RCD’?

The requirement for residual current protection depends on the application and where in the electrical distribution system the RCD sits. The main rule is to have 30mA RCD protection for all final circuits but distribution units further up the chain may (should) have RCD set at a higher current or be disabled.

Are emergency stop buttons dangerous due to accidental activation?

They can be triggered unintentionally, but they’re legally required in many countries and are essential for safety.

What is a Harting earth connection?

It’s a special quick connection for external grounding, it’s an alternative to the more common bolted connection.

Can the emergency stop b e activated from the software?

No.

Powerlock through connection - protected by MCCB or not?

There is no rule that dictates that a Powerlock connection must be able to carry a certain current. The most common Powerlock type connectors are rated 400-500A but its not uncommon to see such connectors fitted to cable rated for much less (95mm2, 120mm2) and in those cases a protected Powerlock out connection makes sense of course.
K
L

Are all 19-pole “Socapex” style connectors compatible?

Unfortunately there is no published standard for this very common and popular connector type. Originally developed by French company Socapex and brought into our industry in the 1970’s by the late Eric Pearce of Showlites, it has since been copied and cloned extensively. From experience we know that certain Chinese made plugs may have too thick pins which can lead to sockets being expanded and later, when mated with normal sized pins, may lead to overheating due to poor contact.
K
L

Are all powerlock type connectors compatible?

Generally speaking yes, but from a liability standpoint, it is best to only mate the same brands wherever possible.
K
L

How much power does a 12/24/48 way distro need?

That depends entirely on what is being powered by the distro. The distro itself does not consume much power, maybe 10-15W.

K
L

Using 3-phase cables as load cables instead of multipins - pros and cons?

It can be tempting from a cost perspective to use common 3-phase cables between the distro and the loads instead of 6/8 circuit cables. But this means running twice as many cables and it’s not possible to do from a distro using RCBOs since such protectors need individual neutrals to each load.

K
L

Are distros built in plastic enclosures more safe than those in metal?

No, this is a myth. We build our distros in metal enclosures because that creates a more rugged product that easier to service and repair than they plastic types. Each panel has a ground connections to ensure electrical safety and to keep electromagnetic interference signals from entering or exiting the unit.

K
L

Can I use a European distro in North America?

No, it is an entirely different electrical system with its own requirements for certification.

K
L

Outdoor vs indoor distros and the IP ratings?

IP-rating is a measure of two things, what size objects that can enter a device and also its ability handle water ingress. Distros intended for indoor or protected outdoor use, are typically rated IP20. Distros suitable for outdoor use are typically rated IP54 or higher.

K
L

Are all Harting 16 connectors wired the same?

Unfortunately not, there are 6-circuit and 8-circuit types and at least two different ways to wire each.
K
L

What constitutes a “final circuit” and why does it need residual current protection?

A final circuit is one that supplies power to appliances via a socket, power to a fixed piece of current consuming equipment. This is called a final circuit because it is the final part of the system
K
L

Power factor, what is it?

The power factor (PF) is defined as the ratio of the real power absorbed by the loads to the apparent power flowing. Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electrical energy. Apparent power is the product of the RMS voltage and current. In a perfect situation, the power factor is one (PF=1.00) but it is typically slightly below that.

Is it possible to make a remote E-stop on the B12?

Yes, it is possible, and we have implemented this for some customers in the past, including several laser companies in the UK. However, please note that the units will need to be returned to us for this modification.

We add a special connector on the back of the unit to which a normally closed E-stop (single pole) can be connected. When the remote E-stop is not in use, a "shorting plug" is inserted into the socket to close the loop and ensure proper functionality.

Can you read out every circuit individually when it comes to leakage to the ground?

No, this feature is not available on the C-Quad, but it is an option on the B-Quad.

Can the C12 be supplied with a cable tail with CEE 63A plug?

There is an option to have a fixed (not removable) input cable for the C12. It consists of a 2m cable fitted with a CEE 63A plug. Exactly the same as we have as a standard for the B12 and B24 units
K
L

Can the C24 be fitted with regular sockets (Schukos, UK13A) instead of True1’s (Channel 21-22-23)?

No, there is not enough space on the rear panel to fit 3x such sockets.

Does the C-Quad come with load monitoring and integrated web server?

Can the Cquad 63A be equipped with 125A CEE instead of powerlocks?

No, please consider our B-Quad unit instead.
