NOTES:
1. Connections: For output terminals, the wire cross sections must be
adapted to the load current and to the
overcurrent protection device
characteristics. The relay rated voltage
must be adapted to the mains rated
voltage. These relays use screw clamp
connections.
2. Mounting: Only in vertical position.
Protect heat-sensitive materials as well
as people from contact with the heat
sink. For non-vertical mounting, the
load current must be derated by 50%.

The SSR requires air convection. Lack
of air convection produces an abnormal
heating. Keep a distance between the
upper SSR and the lower SSR (see
figure on the right). In case of zero
space between two SSRs, reduce the
load current. It’s suggested to maintain
the heat sink temperature under 90°C.
Forced cooling significantly improves the thermal performances.
3. Typical application loads: The DRS relay may handle motor and
resistive loads. For different loads, check the inrush current at turn-
ON and possible overvoltages at turn-OFF or contact the factory.
• Incandescent lamps — Inrush current is generally 10 times the
nominal current for 10ms.
• Electric discharge lamp — These loads often have overcurrent at
turn-ON and overvoltage at turn-OFF. Use 480Vac SSR on 240Vac
mains.
• Transformer loads — Very high inrush current, up
to 100 times the nominal current.
• Capacitive loads — Very high current at turn-On

and overvoltage at turn-Off. Use only zero-cross +
models.

4. Protection: To protect the SSR against a short-
circuit of the load, use a fuse with a I²t value = 1/2
I²t value.

5. EMC:
Immunity: lmmunity levels of the DRS comply with
EN61000-4-4 &5.
