Overview

The Mersen ESK3 (SKU: ESK3) is a specialized Class C HRC fuse designed for critical short-circuit protection in motor controllers and associated components. It adheres to British Standard (BS88) dimensions, ensuring it serves as a direct replacement for older British fuses and HRCII-C fuses. It is crucial to note that this fuse is not dimensionally or electrically interchangeable with standard North American fuses. The ESK3 features a robust ceramic body and a secure bolt-in mounting design. Key specifications include a 600VAC voltage rating and a 3A current rating, with a substantial 200kA I.R. AC interrupting rating. This fuse is specifically intended for short-circuit protection, where overload protection is handled by a separate overload relay. Mersen Class C fuses are CSA Certified and comply with IEC 269-2-1 standards, making them suitable for applications requiring reliable back-up protection for motor control circuits. Its fast-acting nature provides rapid response to fault conditions.
