Feed-through Double Deck Ground Disconnect for Fuse
20% Size Reduction High Wiring Density
for Space Savings
Reliable Rail Connection Time saving for test circuit operations Optimized Circuit Protection
Compact Expert Aligned with fuse
A unique profile for smart use
Easy and ergonomic mounting thanks to the unique profile
of the terminal blocks:
- Easy to handle,
- Reverse mounting error-free.
Clear marking areas
Marking surfaces can be read clearly from any angle in
an enclosure and are larger than standard markers in the
market.
Maximized flexibility
The two terminal blocks central channels-aligned from
4 mm² 10 AWG up to 16 mm² 4 AWG terminal blocks-offer
exibility of use:
- Common and polarity distribution with JB screwless jumper
bars,
- Power distribution with JB85-3 cross-spacing jumpers,
- Continuity control with TP4 or TP2 test adapters,
- Advanced testing (simulation, dielectric control, etc.) prior
customer acceptance with TC test connectors,
- Overvoltage protection and temperature control with
PG5-R2 components holder.
Reduce use of accessories
- One unique end section and circuit separator fits all feed-
through terminal blocks.
Offers efficient space reduction for
switchgears with space constraints
or sensors with multiple connection
constraints.
All Double Deck terminal blocks have
two marking areas as well as two central
channels per deck for:
- Common and polarity distribution with JB
screwless jumper bars.
- Continuity control or Advanced testing
(simulation, dielectric control, etc.) with
TP4, TP2 test adapters and TC test
connectors, on the upper deck only.
Snap-in rail connection for rapid installa-
tion and removal for 4 mm² 10 AWG up to
16 mm² 4 AWG ground terminal blocks.
Simply snap it on the DIN3-TH35 rail and it
is connected to the rail.
Strict qualification tests, in addition to those
required in IEC standard 60947-2, have
been performed to guarantee the reliability
of the snap-in rail connection in mechanical
endurance and lifetime performance.
Our smart design enables block removal
without any risk of damaging the rail
connection part.
Robust screw rail connection for higher
rated sections 35 mm² 0 AWG up to
95 mm² 000 AWG ground terminal blocks.
The ZS4-S compact
version has an identical
profile to the ZS4 feed-
through terminal block
for many benefits such as
identical end section use
The ZS4-S-R1 expert
version has two central
jumper channels aligned
with the ZS6 feed-through
terminal block for conven-
ient alternated distribution
Perfectly adapted for
use with fuse terminal
blocks
The ZS4-SF fits 5x20 mm
fuses for circuit protec-
tion
It has two central jumper
channels for convenient
common distribution and
it is aligned with ZS4-S-R1
and ZS4-S-R2 disconnect
terminal blocks, as well
as the ZS6 feed-through
terminal block for convenient
alternated distribution and
reduced wiring.
The ZS4-SF1 fits 5x20 mm
and 5x25 mm fuses for
circuit protection
Available with blade or plug for easy circuit opening without disconnecting
the wiring.
Also available with built-in test socket screws convenient direct connection
to the test equipment for the following operations:
- Voltage control, voltage continuity control or dielectric tests.
- Total or partial equipment testing.
- Maintenance.
The ZS4-SF and ZS-SF1 are based on the latest version
of the IEC60947-7-3 standard.
The wiring of the terminal block is facilitated and can
be done when the fuse holder is in closed position.
- Easy blown fuse control with the ZS4-SF-R1 and
ZS4-SF-R3 available with blown fuse indicator
24-60 V or 110-230 V for quick identication of fuse failures,
with low leakage current (< 0.5 mA). This feature enables
use on high impedance PLC inputs.
- Also available with built-in test socket screws for convenient
direct connection to the test equipment for test opera-
tions such as voltage control, voltage continuity control or
maintenance.
