The Schneider Electric VZ13 is an add-on neutral-pole module for TeSys VARIO switch-disconnectors, rated 125-175 A at 690 V for use with V5 and V6 switch bodies. Its early-make, late-break contact sequences the neutral ahead of the phase poles on closing and after them on opening.
Fit the VZ13 to either side of a V5 (VBF5) or V6 (VBF6) switch body when the circuit needs a switched neutral alongside the three phase poles; for the smaller V0-V4 bodies, use the matching main-pole or neutral accessory sized for that frame instead, since the VZ13's 95 mm2 terminal does not fit the smaller housings.
