Mem EATON 100 AMP 30mA DOUBLE POLE RCCB RCD A100HE

Product Information

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. It is more a physical size & shape of fitting onto the Din rail inside the fusebox & if the main live bus-bar has a blade or a fork type fixing to the RCD and each MCB.

Memshield 2 – These are also a commercial breaker and come in types B,C & D. These also will fit into all Memera 2000 range boards. MEM first started manufacturing circuit breakers in 1965 and were one of the UK's biggest names in circuit protection. Now they go under the trade name of Eaton but still use the MEM name on some products. 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.The method of installation relating to protective earthing will depend on the operational leakage current (protective conductor current) – see 543.7. The use of a 30mA RCD may be required for several reasons; cable installation, location / application area for the pump etc. Take note of 531.3.2 Operational leakage current (protective conductor current) for the circuit should not exceed 30% of the RCD sensitivity. Designing to pass an immunity test at 200V/m from 10kHz to 6GHz (the Def Stan) is far more demanding that one at 3V/m (CE marking for type B, domestic situations) or even 10 V/m (CE marking industrial), there is a reason that all the geen boxes are milled from solid metal and have EMC gaskets everywhere. In your own words - It is not appropriate electrotechnical language, its generic and anyone following that as a lead will not carry out an appropriate assessment.

To be honest that is even sillier, as there the thing that has to radiate for its correct operation is being screened. For existing installations, problems associated with the following may indicate that Type F is required in place of Type A: If it is the main switch.. this would involve removing and reconnecting the main incomming supply tails.. 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. High frequency current components can saturate the RCD, preventing detection of 50Hz residual currents.

Would you be able to reveal the make and model of the RCD that trips, and the make and model of the smart meter? So question one does it pass when tested with a RCD tester? If so what makes you think it is faulty? I am sure the one in my old house was tripping due to surges when a neighbour was welding. Two identical RCD's would hold for 18 months without a problem, then trip for seeming no reason for couple of weeks, then again two years no tripping.

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. 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 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 DC link values of capacitance and voltage, do not result in smooth dc values < 10 mA, being imposed on the AC pulsed wave form.

Memera 2000AD – These have a narrow terminal and only fit boards specifically marked Memera 2000AD. They won't fit in older boards. Otherwise, I'm not quibbling the need for proper spur to garage, which will separate off two freezers from kitchen, but how do you people feel about this diagnosis? My own insulation tests with mega meter to each unplugged appliance have found no resistance issues, which given he found no wiring issues, leaves no obvious cause except as he thinks maybe too much total freezer earth leakage. Intermittent faults like tripping can send you mad as we all know, is this a good course of action? RCD failing to trip when the appliance is running, and the RCD test button is operated, could be an indication that the appliance is affecting the RCD. 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. Should be neutral - but I accept the motivations of the reader may focus on what is more important to them.
