Product details

The LV846342 is a Schneider Electric MasterPact MTZ2 20 HH switch-disconnector, rated 2000 A continuous at 440 V AC in AC-23A and AC-3 utilisation categories. That 2000 A figure is the operational current it carries in distribution service — sized for main incoming feeders or large bus couplers in industrial switchboards. It is also rated for isolation per EN/IEC 60947-3, so it provides a visible-gap-equivalent disconnection for safe maintenance access.

The making capacity Icm is 220 kA peak, which handles the asymmetrical first half-cycle of a short circuit.

Fixed-mount design — 537 mm wide, 352 mm high, 300 mm deep. Four-pole configuration with right-side neutral. IP30 front protection means it is suitable for enclosed switchboard installation where the door provides the environmental seal. Mechanical durability is 15,000 cycles with periodic preventive maintenance; electrical durability is 8,000 cycles at 440 V in AC-23A duty and 6,000 cycles in AC-3 motor-switching duty.

Frequently asked questions

Where can I buy LV846342 and what is the lead time?

The LV846342 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price.

What is the closest alternative to LV846342 in the MasterPact family?

Within the MasterPact MTZ2 range, the LV846342 is the 2000 A, 4-pole, fixed-mount, right-neutral variant. The closest alternative would be a different frame size (MTZ1 or MTZ3) or a different pole/neutral configuration, but those change the physical footprint and ratings — there is no pin-compatible drop-in substitute. For a direct replacement, this exact order code is the fit.

What compliance documentation does Schneider provide for LV846342?

The LV846342 is designed and tested to EN/IEC 60947-3 (switch-disconnector standard) and EN/IEC 60947-2 (for the breaking capacity ratings). It carries a suitability-for-isolation declaration per EN/IEC 60947-3. Standard Schneider documentation includes a declaration of conformity, test certificates, and installation manuals — available on request with the RFQ.
