Electronic circuit protector REX12
Description
The new electronic overcurrent protection REX12 consists of the
supply module EM12-T and the single or double channel electronic
circuit protector REX12-T which allows modular side-by-side mounting.
The modules with a width of only 12.5 mm feature push-in
technology including press release buttons and allow time-saving and
maintenance-free wiring without tools. The supply module is designed
for DC 24 V and 40 A and accommodates max. 10 mm² with wire
end ferrule as a plus (+) supply. On the load output side the circuit
protector can be wired with 2.5 mm².
The new generation of electronic overcurrent protection REX12
combines flexibility with a compact design. It is exactly tailored to the
needs of machine and panel builders. And what is more: no additional
accessories are required when connecting the individual components
electrically and mechanically. This helps save time and money!

Temperature factor / continuous duty
The time/current characteristic depends on the ambient temperature.
In order to avoid premature trip, the rating of the circuit protector has
to be multiplied with a temperature factor and has to be accounted
for when mounted side-by-side (see chapter Technical Information).
Temperature factor table:

Note: When mounted side-by-side, the devices can carry max. 80 %
of their rated load or a different rating has to be selected (see chapter
Technical Information).
Note:
With high temperatures, the load current warning threshold “warn limit
typically 0.8 x IN” will be reduced in accordance with the temperature
factor.

Electronic circuit protector REX12
Description – EM12-T supply module
Dimensions EM12-Txx supply module
The EM12-T supply module receives the DC 24 V supply voltage, e.g.
from a switched mode power supply, and distributes it to the mounted
circuit protectors via the integral connector arm of the REX12-T.
The potential-free auxiliary contact in the EM12-T indicates
any detected failures through the circuit protector, e.g. to the
superordinate control unit (CPU).
