Product De scrip tion

The industrial, 1-phase relay

with antiparallel thyristor out-

put is the most widely used

indus trial SSR due to its

multiple application possibil-

ities. The relay can be used

for resis tive, inductive and

capacitive loads. The zero

switching relay switches ON

when the sinusoidal curve

crosses zero and switches

OFF when the current cross-

es zero. The built-in varistor

secures transient protection.

The LED indicates the status

of the control input. The clip-

on cover secures touch pro-

tection (IP 20). Protected

output terminals can handle

cables up to 16 mm

RAM..G Short Circuit Protection Protection Co-ordination, Type 1 vs. Type 2: Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. In type 2 co-ordination the device under test will still be functional after the short circuit. In both cases, however, the short circuit has to be interrupted. The fuse between enclosure and supply shall not open. The door or cover of the enclosure shall not be blown open.
