Module 17plus is a power distribution system for use with electronic
circuit breaker *S20-0...
Each module accommodates two breakers with an individual housing
width of only 12.5 mm and fits onto all industry standard mounting
rails.
The two-way modules can be interconnected to provide as many
ways as required with a terminal block fitted at each end for
connection of signalling circuits. A distribution busbar can be fitted
on the supply side of the modules (positive pole) though each pole of
multipole circuit breakers must be individually connected.
Electrical connections are by means of spring-loaded terminals. The
reference potential for the *S20-0.. (Gnd pin 11) is also looped
through and connected to the terminals at the sides.
The integral make contact of the *S20-001 (SC-SI) can be tapped at
terminal 12 of the relevant channel (individual signalisation).
The integral make contact of the *S20-002 (SC-SI) can be tapped at
terminal 12 of the relevant channel (individual signalisation).
The *S20-003 has an integral signal contact (change-over contact). The
contact SC-SO is used for group fault signalisation. For this purpose the
contacts for signalisation are connected in series in the Module 17plus
and are connected to the terminal blocks via two terminals (13,14). It is
possible with a test probe to contact the series connection in each
module and detect possible interruptions.
All internal wirings for the ground potential and the group signal are
established by the modular mounting of the individual Modules 17plus.
Meets the requirements of UL60950.
