Overview

The ABB E 91/50 (SKU: E91/50) is a single-pole fuse holder designed for industrial circuit protection, specifically for cylindrical fuses rated up to 50A. This unit is part of the ABB E 90 50/125 series, engineered to protect against overloads and short circuits. It is compatible with 14x51 mm cylindrical fuses and operates at AC-20B. The housing is constructed from self-extinguishing, high-temperature-resistant thermoplastic, with all materials UL listed. The contact clips are made of silver-plated copper, ensuring reliable conductivity. For enhanced operator safety during maintenance, the E 91/50 can be sealed or padlocked in the open position. Versions with a blown fuse indicator (LED) are available for quick visual confirmation of fuse status, reducing downtime. This fuse holder occupies one module on a DIN rail and is fully compatible with ABB UL 508 busbars for efficient installation in industrial control panels and machinery. With cURus approval, the E 91/50 is suitable for integration into UL certified machines. The rated current (In) is 50A. Manufactured in the US, this fuse holder is ideal for applications requiring precise current control and rapid fault isolation, such as motor control centers, power distribution systems, and renewable energy installations. The E 91/50 provides robust circuit protection for industrial environments, supporting currents from 50A to 125A within the E 90 50/125 range.
