ZS4-S-R2 screw clamp terminal blocks
Disconnect with lever - 6 mm 0.236 in spacing

Description
4 mm²
Simplify the disconnect operations for the disconnect terminal blocks installed next to fuse terminal blocks ZS4-SF:
10 AWG – With the same profile as ZS4-SF, the ZS4-S-R2 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
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
6 mm 0.236 in spacing 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).
