To ensure that the solid state relay is fully protected, we recommend the use of quick-blow fuses. Their role is to protect the solid state relay against
short-circuits. The fuse rating is determined as follows : I
state relay you have selected.
These fuses can be obtained from your usual “FERRAZ” distributor (please consult us for a list of stockists).

Characteristics
Particular attention must be paid to thermal considerations in order to improve the
reliability and power of solid state relays. It is extremely important to consider the
quality of the interface between the relay and the heatsink (ROcs). Air pockets or
gaps risk causing hot spots and a significant rise in temperature. Compared with
the published thermal dissipation curves, performance is likely to be inferior or
inconsistent. See the power curves and the description of heat transfer and of the
heatsink presented in the corresponding individual technical data sheets.
We are pleased to offer cut-out pads of Thermstrate® thermal interface which
replace messy and uneven heat transfer compounds. This pad is made of an
aluminium substrate covered on each side with a "touch-dry" thermal compound. If
the temperature exceeds 51°C, the thermal compound wetting action allows it to fill
any gaps, while its natural capillary action draws it to the edge of the interface
between the mating surfaces, thus preventing it spreading.
To order a supply of pads with the corresponding relay, please specify:
– For the G, GA5, GF and GT ranges
– For the 3-phase GA0 range and the GA3 range
