Product details

The MGN15712 is a Schneider Electric Acti9 SBI fuse-disconnector — 3 poles plus neutral, rated 50 A at 690 V AC, built for 14 x 51 mm fuses with an AM GG curve.

The 690 V AC rated operational voltage covers standard industrial supplies. The 50 A maximum rating is the fuse-limited current; the disconnect itself carries the full 50 A through screw-clamp terminals accepting 2.5 to 25 mm² cable, tightened to 3.5 N·m.

Frequently asked questions

Where can I buy MGN15712 and how is it quoted?

We source the MGN15712 to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here because the supply is per-request.

What is the closest alternative to MGN15712 in the Acti9 range?

The MGN15712 is a 3P+N 50 A fuse-disconnector for 14x51 mm fuses. A direct functional replacement would be another Acti9 SBI variant with the same pole count and fuse size — but since the entire SBI series is being phased out, check the current Acti9 catalog for a comparable fuse-switch-disconnector. No single pin-compatible drop-in exists; verify footprint and terminal spacing before substituting.

What compliance documentation does Schneider provide for MGN15712?

The MGN15712 carries IEC EN 60947-3 compliance, which covers the disconnect and fuse-switch standard. Schneider typically provides a Declaration of Performance and CE marking for Acti9 devices; RoHS and REACH declarations are available on request through the RFQ process.
