Overview

The Mersen ESK25 HRC MISC Class C Fuse (SKU: ESK25) provides high rupturing capacity (HRC) short-circuit protection for industrial applications. Rated at 600V AC/DC and 25A, this fuse is designed for Class C applications requiring fast-acting response to fault conditions. It features BS88 dimensions for compatibility with British standard fuse holders and is suitable for motor controllers, power distribution panels, and industrial machinery where overload protection is provided by separate overload relays. Key specifications include a 200kA interrupting rating (AC) and 40kA (DC), ensuring reliable operation in high-fault current environments. The fuse is CSA Certified HRCII-MISC and meets IEC 269-2-1 standards. Its ceramic body construction provides durability in harsh industrial settings. The ESK25 is part of Mersen's Class C fuse series, offering precise short-circuit protection without dimensional interchangeability with North American fuse types. Ideal for short-circuit and backup protection in motor controllers, industrial machinery, and power distribution systems. The 25A rating balances moderate current demands with robust fault interruption capability.
