MEM Memera 2000 - ALB161 - 16a Type B Single Pole MCB

Product Information

Fortunately the situation with Bill and MEM MCCB's is not as confusing. Firstly MCCB's are made to a different standard to MCB's, BS60947-2. Whilst that standard has been updated to allow for new technologies it still remains as the current British Standard. After 1994 the British Standard of BS60898 came into effect and the range was changed to Types B, C & D and now included double pole mcb's as well. RCBO's were now being widely used and theses were available in Types B & C although it's rare to see Type B in use as most installations were commercial.

Not all pods are the same, some have long leads for triple pole boards and some have short leads for use in domestic boards. Also worth mentioning that the pods will fit the Memera 2000 range of MCB's as well but only the part numbers that start ALB or ALC. Square D was bought out by Schneider in 1991 and although they changed the appearance of the circuit breakers the later versions will still fit the older boards. 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. The Polestar range of breakers was unique because they had a higher than usual fault rating of 16kA where standard breakers at the time were 6kA and 9kA. What this meant was that Polestar could be used in areas where a high kA was required without having to use Moulded Case Breakers (MCCB's) or HRC fuse carriers. Crabtree Polestar breakers are also unique in that they are much wider (25mm) than a standard mcb (18mm). This extra width was needed for the bigger arc splitter to allow for a higher kA rating.Loadcentre – This was a new range introduced by Schneider but using the brand name of Square D. This is more of a commercial range with types B,C & D available (B type only in single pole). They have a breaking capacity of 10kA and. Later versions were branded as Schneider but are identical to the Square D. These will also fit the Qwikline II boards.

Initially the range was made to BS3871 standards so Types 2 & 3 were available from 6A up to 63A in single and triple pole. RCBO's were also available but they were initially referred to as MCB/RCD units as the term RCBO was not really established as yet.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. 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? Qwikline – This is the most common Square D breaker and the part numbers will always start QO. Available in types 2,3 & 4 with M6 or M9 breaking capacities for early BS3871 breakers or types B,C & D with 6kA or 10kA breaking capacities. These styles have the push-fit electrical connection and push-fit mechanical connection. These are available in single, double and triple pole.

All MCCB's in MEM's Memshield 2 range or Bill's Talisman Plus range are branded as such. Even though Eaton bought out Delta in 2003 they maintained the old branding until they came out with the latest range, Memshield 3. Even though they are using the Memshield brand all breakers are now marked as Eaton. Still Confused? You can also buy MCB's pre-fitted with a pod in both the Memshield 2 and Memera 2000 ranges. These are usually just the 30mA size but field fit versions are availble is the following sizes:The older RCD does seem to be affected by spikes, so likely a SPD would stop it, but a consumer unit is a type tested distribution unit, and to retain the type testing only items recommended by the manufacturer can be used, even if they seem to fit.
