Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.

GENERAL APPLICATION GUIDELINES
A relay may encounter variety of
am bient conditions during actual use
resulting unexpected failure.
[1] METHOD DETERMINING SPECIFICATIONS
In order use the relays properly, the
characteristics the selected relay
should well known, and the conditions
of use the relay should investigated
to determine whether they are matched
to the environm ental conditions, and at
the same time, the coil conditions,
contact conditions, and the ambient
conditions for the relay that actually
used must sufficiently known in
