ZS4-S-R3 screw clamp terminal blocks

Disconnect with lever - 8 mm 0.315 in spacing

4 mm² Description
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.

Recommendation for best usage: in horizontal assemblies, disconnect terminal blocks should be mounted
32.9 1.30" with fixed foot on top (power side) so that the disconnect lever does not partially close through gravity.
8 mm 0.315 in spacing 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 - Flexible conductor (when applicable) is a mandatory information required by IEC, UL and CSA standards (Copper conductors).
