Description
The compact and flexible all-in-one solution REX consists of several
coordinated modules. It comprises the EM12-T type supply modules
for the plus and minus potential, via a single or double channel
REX12-T electronic circuit protector, which can be mounted side by
side in any number, and the PM12-T potential extension modules
for plus and minus multiplication. The 12.5 mm slim modules are
designed completely in push-in technology and thus allow a tool-free
and time-saving wiring.
The protection modules can be mounted on the mounting rail side by
side in combination with the EM12-T and the PM12-T, just as needed.
Furthermore, no additional accessories are required, as they can
be connected electrically via flap-hinged mechanism. The REX12-T
circuit protector offers selective overcurrent protection, by reacting
faster to short circuits and overload than the connected switch
mode power supply. Capacitive loads up to 20.000µF are switched
on without any problem. The circuit protectors are available in all
common fixed and adjustable current ratings ranging from 1 A to 10 A.
Besides the UL508listed approval, UL 121201, Class Division and
NEC Class2, REX12-T exclusively meets the requirements of cable
protection according to EN60204- 1.
