RA2A
Applications
This relay is designed for use
in applications in which it is
exposed to high surge condi-
tions. Care must be taken to
ensure
when the relay is to be used at
high sustained currents. Ade-
quate electrical connection
between relay terminals and
cable must be ensured.
Thermal characteristics
The thermal design of Solid
State Relays is very important.

heatsinking
It is essential that the user
makes sure that cooling is ad-
equate and that the maximum
junction temperature of the
relay is not exceeded.
If the heatsink is placed in a
small closed room, control panel
or the like, the power dissipation
can cause the ambient tem-
perature to rise. The heatsink
is to be calculated on the basis
of the ambient temperature and
the increase in temperature.
