ZS4-S-R3 screw clamp terminal blocks
Disconnect with lever - 8 mm 0.315 in spacing

Description
4 mm²
Simplify the disconnect operations for the disconnect terminal blocks installed next to fuse terminal blocks ZS4-SF1:
10 AWG – With the same profile as ZS4-SF1, the ZS4-S-R3 disconnect lever is easily operated by hand and the wiring
of the alternated disconnect and fuse circuits is easier.,
– Neutral cartridge CN5 5x25 included.

8 mm 0.315 in spacing Recommendation for best usage: in horizontal assemblies, disconnect terminal blocks should be mounted
with fixed foot on top (power side) so that the disconnect lever does not partially close through gravity.
Furthermore, as specified per IEC 60947-7-1, disconnect terminal blocks are intended to be used for temporary
disconnection at zero potential and at no load.
The connecting capacity data for one Rigid: Solid/Stranded, or one Flexible conductor (when applicable) is a mandatory information required by IEC, UL and CSA standards (Copper conductors).
All other data are provided as supplementary information only. For more details, please consult our CB, UL or CSA certificates and technical datasheet available on http://www.TE.com
