Thermal specifications .
Current according ambient temperature :
Ø The curve "1" gives the limits of the product.
The temperature reached are acceptable for the com-
ponents. These values are in compliance with most of
SSRs manufacturers.
In a cabinet with a minimum of ventilation or a non
permanent current, these values are correct.
Ø The curve "2" gives the limits of the product
according to EN60947-4-3 with a maximum rise
temperature of 50°C (@40°C) for a permanent
working and in air calm ( test during 8 hours).
Ø For a non permanent current, you can calcule
the average power = Pd x duty cycle and check the
rise temperature : Tj = Pd x Rthj/a (Pd and Rthj/a are
given page 2)). The junction temperature must not
exceed 125°C at the maximum ambient temperature.
The maximum current is limited to the size of the
thyristors = 50A.
Ø The thermal constant (Cth) of the product is 7
minutes. That means the rise temperature is only 63%
of the stabilized temperature after a running time of
7 minutes.

Overload current .
1 - No repetitive Itsm is given without voltage
reapplied . This curve is used for the
determination of the protection.

Warning ! semiconductor relays don't provide any galvanic insulation between the load and the mains. Always use in
conjunction with an adapted circuit breaker with isolation feature or a similar device in order to ensure a reliable isolation in the
event of wrong function and when the relay must be insulated from the mains (maintenance ; if not used for a long duration ...).
