Interruptor-seccionador de fusíveis ABB STOTZ-KONTAKT E91/32PV, bipolar, 32 A, 1000 V DC, gPV cilíndrico 10x38 mm, calha DIN 2CSM204713R1801

Rated for 1000 V DC and 32 A, the ABB E91/32PV is a two-pole fuse switch disconnector built for photovoltaic string protection. It accepts 10 x 38 mm cylindrical gPV fuses and mounts on a standard DIN rail, making it a direct fit for solar combiner boxes and inverter DC inputs.

Overview

The E91/32PV combines a load-break switch with a fuse holder in a compact 3-module housing. It provides visible fuse status indication, so a blown fuse is immediately apparent without disassembly. The unit is designed for use in PV systems up to 1000 V DC, where reliable isolation and overcurrent protection are critical.

What stands out

• High DC voltage rating: 1000 V DC, suitable for modern PV strings.
• Compatible with 10 x 38 mm gPV cylindrical fuses, a common PV fuse size.
• Visual fuse status indication for quick fault identification.
• DIN rail mounting (EN 60715) for easy installation in standard enclosures.
• High mechanical durability: 8500 cycles, ensuring long service life.
