Mem EATON 100 AMP 30mA DOUBLE POLE RCCB RCD A100HE

Product Information

For single phase inverters used in motor speed control, the characteristics of the equipment will determine if Type A, F or B is required, to meet Regulation 531.3.3 For 3 phase inverters which do not incorporate isolating transformers, Type B RCDs must be used to meet the requirements of Regulation 531.3.3 For additional information. I feel like BIG BUSINESS is trying to pull a fast one with the new 18th edition regs, they are trying to shift responsibility for their sometimes obvious poor standards onto the little man at the bottom of the food chain. It's pretty obvious that insurance companies are trying to get out of paying for damage caused by products that quite frankly should not be in peoples homes in the first place. For the person who asked about Smartmeter, yes one fitted in last year and quite close to CU (2 meters?). Though similar episode of nuisance tripping preceded its installation and went away of its own. What are you thinking about this? In some other countries in Europe (perhaps not coincidentally the ones commonly using 3-phase supply to homes), it's much easier to find type-A or even type-B.

Type F RCDs are not designed to detect smooth dc residual currents. They will still trip within safe limits with < 10 mA smooth dc superimposed on a 50Hz pulsed residual current. Add to that the changes that have been imposed on the local supply networks i.e. green energy they have caused a situation that is going to result in frequent surges and transient voltages being produced all the time hence we now need to install surge protection or the likelihood is that if a surge occurs at a property and there is no surge protection then the blame will be passed on to the little man again.So - please help me - have I lost touch with the right places to buy RCDs in the UK? Where can one get a fairly broad selection of different types (A, B) at reasonable price? Why do I find almost entirely AC? The revised RCD guidance in 531.3.3 is precise. The appropriate Type of RCD must be selected, based on the characteristics of the residual current and the equipment that is likely to be connected to the RCD protected circuit.

This handy RC Unit (residual current unit) has been designed for installing on to any standard 1P or 1P+N Eaton MCB with a 10kA, 15kA & 6kA rating to create an RCBO. The MR30 RC POD unit is ideal for standard applications with a 230-240 VAC voltage rating and 30 mA breaking capacity and is field fitable. Fully compliant with Standard 61009, this capable MR30 POD is utilised in numerous industrial and commercial applications due to its versatility and ease of assembly. Memera 2000AD – These have a narrow terminal and only fit boards specifically marked Memera 2000AD. They won't fit in older boards.I believe the article makes it clear that the their are 4 Types of RCD that may need to be considered - Quote from the article -

Memshield 1 – These are a commercial breaker and come in various types (Type 2,3,B,C & D) depending upon the age. Most are M9 rated. Single-phase inverter designs, applied in washing machines and handheld appliances, containing variable speed features, may produce mixed frequency leakage currents. Appliances containing inverters and motors, can be used with Type A RCDs, if:Requirement for a transient resistance feature < 3 kA and short 10 ms time delay. **Note: Type A transient resistant RCDs only meet EN 61008/9 for general UK 50Hz residual currents. There's never going to be a perfect solution but there does need to be a less complex solution than there is. The term general purpose relating to Type AC devices should not be taken out of context i.e. it is the most basic RCD, suitable for detecting a simple full sine wave residual current at 50Hz.
