Solid State Relay Dissipated Power Calculation
Heatsink Thermal Resistance Calculation
Maximum surrounding air temperature 40°C suitable for use in pollution degree 2 or better.
- Procedure for mounting on heat sink: The module-heat sink contact surface must have a maximum planarity error of 0.05mm. and
maximum roughness of 0.02mm. The fastening holes on the heat sink must be threaded and countersunk.
Attention: spread 1 gram of thermoconductive silicone (we recommend DOW CORNING 340 HeatSink) on the dissipative metal sur-
face of the module. The surfaces must be clean and there must be no impurities in the thermoconductive paste. As alternative it is
also possible to use the graphite film SIL-GQ available as accessory.
Alternately tighten the two fastening screws until reaching a torque of 0.4...0.6 Nm (3,5 - 5,3 lb.in). Wait 5 minutes for any excess
paste to drain. Alternately tighten the two fastening screws until reaching a torque of 1.2...1.4 Nm (10,6 - 12,3 lb.in).
Short circuit protection The product variants listed in the table "SCCR COORDINATION FUSES" are "Suitable For Use On A Circu-
it Capable Of Delivering Not More Than 100,000 A rms Symmetrical Amperes, 600 Volts Maximum when Protected by fuses.
Attention: the opening of the branch-circuit protective device may be an indication tha a fault has been interrupted. To reduce the
risk of firee or electric shocks, currentcarryng parts and other components of the device should be examinated and replaced if dama-
ged. If burnout of the device occurs, the complete device must be replaced or equivalent.

(#) Nel caso di inserimento di due conduttori nello
stesso morsetto essi devono essere di uguale
sezione.
Nota: Le sezioni minime e massime indicate sono
riferite a cavi in rame unipolari isolati in PVC.
(#) When inserting two leads in the same terminal
they must have the same cross-section
Note: The minimum and maximum sections shown
refer to unipolar copper wires isolated in PVC.
Ingombri:
Fissaggio a dissipatore:
Connessioni:
- Utilizzare cavi di collegamento rame 75°C il cui diametro é riportato in tabella Fig. 3.
- Applicare sui morsetti una coppia di serraggio indicata in tabella Fig. 3.
- I gruppi statici devono essere collegati con protezione al corto circuito da fusibile come indicato in Fig. 4.
Dimensions:
Installation on sink:
Connections:
- Use 75°C copper (Cu) conductor only, for diameter see Fig. 3.
- The terminal tightening torque is indicated in table Fig. 3.
- The solid state group must be connected using proper fuses against short circuits, as showed Fig. 4.

Pd GQ..15/25 = 1.45 * IRMS [W] Pd GQ..50/90 = 1.35 * IRMS [W]
IRMS = single-phase load current
Rth = (90°C - max amb. T) / Pd
Max. amb. T = max air temperature inside the electrical cabinet.
Use a heatsink with thermal resistance inferior to the calculated one (Rth).
