The AD monopolar rail base is a single-pole fuse holder rated 32A at 1000Vdc, designed to accept 10×38mm cylindrical cartridges (Freder type). It clips onto a standard 35mm DIN rail and includes a built-in indicator light for immediate visual detection of a blown fuse.

The 1000Vdc rating makes it specifically suited for photovoltaic string protection, battery storage systems, and other DC distribution applications where the standard 500V AC rating would be insufficient. IP20 protection rating confines its use to indoor enclosures.

Key Features

• Single-pole (one-pole) configuration
