RE: FW: 60950-1:2006 clause 2.5 - Limited power sources
That's my feeling - it's an illogical exclusion. At most the standard should disallow the use of any (ie technology neutral) device that has not been tested to a relevant standard that takes cycle life into account, but to pick on auto-reset electromechanical devices while allowing auto-reset solid state devices seems very odd, especially since the latter are more likely to be damaged by surges and the like.

The language from '950 that I objected to was regarding automatically resetting overcurrent protective devices, so rather than a circuit breaker it would be something like a thermal auto-reset device that I would call a current limiter or a circuit protector not a breaker. Semantics to some extent, but auto-reset was the main attribute for this discussion. Well, if it's not a circuit-breaker (electromechanical, and therefore reliability is an issue), it makes even less sense to allow PTCs. I suspect that the ban on auto-reset was lifted for PTCs because if not it would be an absolute ban on their use. But it's not logical. -- OOO - Own Opinions Only.

RE: ENEC european complaince
While not mandatory the ENEC Mark can be useful on components as some Agencies will accept this Mark as showing compliance to the applicable component standards. I have found this useful when getting a CB report for a product which incorporates an ENEC Marked safety critical component.

Of course, the LVD doesn't apply to components, but even so, a certificate from an accredited test lab that the component complies with the relevant IEC or UL standard is just as acceptable for CB, without attracting the licence fee for the ENEC mark. -- OOO - Own Opinions Only.
