Overview

The ABB E93N/50S is a 3-pole fuse holder designed for industrial circuit protection against overloads and short circuits. Rated for 50 A, it accommodates cylindrical fuses measuring 14x51 mm, making it ideal for applications where precise current protection is critical. This model includes a blown fuse indicator (LED) for immediate visual confirmation of fuse status, simplifying maintenance and troubleshooting. Constructed from self-extinguishing thermoplastic with UL-listed materials, the housing resists high temperatures and ensures safety during operation. Silver-plated copper contact clips provide reliable conductivity and low contact resistance, enhancing long-term performance. The E93N/50S is fully compatible with ABB UL 508 busbars, enabling quick and easy installation in industrial control panels and machinery. For operator safety, the fuse holder can be sealed or padlocked in the open position during maintenance. With cURus approval, it meets UL 508 standards for installation in certified machines. Part of ABB Electrification’s E 90 50/125 series, this fuse holder is manufactured in the USA and supports industrial applications requiring 50 A to 125 A protection. The 3-pole design ensures balanced current distribution across phases, making it suitable for three-phase systems in manufacturing, automation, and power distribution environments.
