Eaton Bussmann 110EET High Speed British Standard Fuse, 110A 690V, Class aR Offset Bolted Tags - Pack of 10

The Eaton Bussmann 110EET is a high-speed, British Standard (BS88) fuse designed for the specialized protection of power semiconductor devices. Featuring a sophisticated double-barrel construction with offset bolted tags, this fuse delivers excellent current-limiting performance and high interrupting capacity. It is specifically engineered to minimize energy let-through (I²t), thereby preventing damage to sensitive electronic components in industrial power systems.

Key Features

• Precision Semiconductor Protection: Utilization category aR ensures rapid-acting protection for diodes, thyristors, and other semiconductor components.
• Superior Interrupt Rating: Capable of clearing fault currents up to 200 kA RMS Symmetrical at 690 VAC and 50 kA at 500 VDC.
• Optimized Thermal Performance: High-efficiency double-barrel design results in low power dissipation (27W at rated current) and reliable operation in heavy-duty environments.
• Robust Bolted Terminal Connection: Equipped with M8 offset bolted tags and a 71 mm center-to-center distance for secure, vibration-resistant installation.
• International Safety Standards: Fully tested and certified to BS88 part 4 and IEC 60269-4 standards. It is UL Recognized, CE marked, and RoHS compliant.
