in applications in which it is

exposed to high surge condi-

tions. Care must be taken to

ensure proper heatsinking

when the relay is to be used at

high sustained currents. Ade-

quate electrical connection

between relay terminals and

cable must be ensured.

In the design of the output

bonding of the copper layer

and the ceramic substrate has

been applied. This is to en-

sure uninhibited heat transfer

makes sure that cooling is ad-

junction temperature of the re-

lay is not exceeded.

rms

t_ON+ t_OFF

If the heatsink is placed in a

small closed room, control

panel or the like, the power

dissipation can cause the

ambient temperature to rise.

The heatsink is to be cal-

culated on the basis of the

ambient temperature and the

increase in temperature.

Ex: RA 24 50 -D 06:

Load current = 45 A

_ON= 30 s

_OFF= 15 s

The relay has been designed

for applications requiring lar-

ge numbers of load cycles.
