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.

In addition, when transporting storing
relays while they are tube packaged,
there are cases when the tem perature

relay, switching the contacts the
presence its gas causes silicone to
adhere the contacts and may result in
contact failure (in plastic sealed types,
too). This corrodes the internal
metal parts and adversely affects
operation.
