Overview

The Mersen Q226311 BS88 gM Type B1 fuse-link is a motor protection fuse designed for industrial circuits. Rated at 415VAC and 240VDC, this fuse-link delivers a rated current of 100A with a gM (motor protection) rating of 125A, ensuring optimal overload and short-circuit protection for motors and transformers. It meets IEC 60269-2 section II and BS 88 part 2 standards, providing reliable performance in demanding environments. Key specifications include a breaking capacity of 80kA AC and 40kA DC, a pre-arcing I²t of 16,000 A²s, and a clearing I²t of 78,400 A²s for fast fault interruption. The central bolted tag design allows secure mounting onto busbars or within fuse interruptors/disconnectors, preventing unauthorized replacement with higher-rated fuses. With a compact design (82g weight) and low power dissipation of 9W, it ensures energy efficiency and ease of integration. Ideal for motor protection in industrial machinery, HVAC systems, and power distribution panels, the Q226311 fuse-link is manufactured in the US by Mersen. Compatible with BTIS42V100M125 fuseholders and similar systems, it provides a cost-effective solution for critical circuit protection.
