Why Choose the ABB E9320S Fuse Holder?
The ABB E9320S, type designation E 93/20S, is a compact and reliable three-pole fuse switch disconnector designed for overcurrent and short-circuit protection in industrial and commercial electrical installations. As part of the ABB E 90 series, it accommodates standard 8.5 × 31.5 mm cylindrical fuse links and provides a modular DIN-rail-mounted solution for three-phase electrical distribution and control systems.
The E 93/20S combines fuse protection with switching and isolation functionality, allowing three protected poles to be disconnected together when required. The S version incorporates an LED blown-fuse indicator, providing convenient visual indication of fuse status and helping maintenance personnel identify a failed fuse more quickly.
With a rated operational current of 20 A, the E9320S supports AC-22B operation at 400 V AC and AC-20B operation at 690 V AC. Its three-module DIN-rail format, IP20 protection and compatibility with ABB S 200 series busbars make it well suited to compact industrial distribution boards and machinery control panels.
