Mem EATON 100 AMP 30mA DOUBLE POLE RCCB RCD A100HE

Product Information

Type A RCDs are not designed to detect smooth dc residual currents. They will still trip within safe limits with < 6 mA smooth dc superimposed on a 50Hz pulsed residual current. This information should be held on record, with other design criteria and the Installation Test Certificate for the premises. This will be required in the event of claims for negligence (Public liability insurance). 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. The method of installation requires 30mA RCD protection – e.g. Regulation 415.1 & 522.6.202. Dedicated circuit feeding an immersion heater, conventional oven or cooker, with resistance heating elements. UK electricians can still make informed technical decisions. This is explained in Chapter 12, 13 and Chapter 30. The Electrician is responsible, not the Technical committee, to make the decision on which device is appropriate for the installation. 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. and the RCD should be selected based on the characteristics of the connected loads.

Memera 2000 – There are several different styles of MCB's in this range but all will fit any Memera 2000 board. 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. Should be neutral - but I accept the motivations of the reader may focus on what is more important to them.

My topics

The MR 30 is one of their most popular products. The Memshield 2 MR30 RCBO Pod is a residual current operated circuit breaker that can be added to any standard 1 pole or 1 pole + N Eaton MCB. It is a Miniature Circuit Breaker with the function of a Residual Current Circuit Breaker and is fully compliant with IEC 61009. but mounted above the old Wylex fuse boxes, however done before the rules changed as to electrical equipment in the control of an ordinary person. But still today we have isolators before the CU to comply with HSE rules an live working, so not sure if we can still mount SPD or RCD in separate box before or after main CU?

Interesting Comments you are entitled to your view, but I am not sure about your motivations - as the article does not say that you cannot use Type AC RCDs.

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. There's never going to be a perfect solution but there does need to be a less complex solution than there is. What I would say is look at the article as a whole, as it makes it quite clear that 531.3.3 refers to 4 Types of RCD, and the points to consider when selecting RCDs for circuits containing various items of equipment. It also makes the point about consulting the manufacturer of the equipment for advice. Type AC RCDs are in clause 531.3.3 of BS7671 2018, because they are still in EN 60364-5-53 2015. The UK have just adopted this line from the EN standard. 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.
