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.

sealed type) should considered for
applications atm osphere with dust,

If relay and magnetic switch are
mounted next each other single
plate, the relay contacts may separate

when the agnetic switch operated
and result faulty operation.
In addition, when transporting storing

there are cases when the tem perature

In this case, use substitute that not

In this situation, sure consult the
individual specifications.
