Why Choose the Mersen CMC81I Modulostar Fuse Holder?
The Mersen CMC81I, item number X1062689, is a compact single-pole cylindrical fuse holder designed for reliable overcurrent protection in industrial electrical distribution, control and machinery applications. Part of the established Mersen Modulostar® CMC8 series, it accepts standard 8.5 × 31.5 mm and 8 × 32 mm cylindrical fuse-links.
This model includes an integrated visual blown fuse indicator, allowing maintenance personnel to identify an operated fuse quickly without removing it from the holder. Its finger-safe construction provides an IP20 degree of protection, including during fuse replacement, helping improve operator safety inside electrical control panels.
Rated for operation at up to 400 V AC and 25 A, the CMC81I is suitable for protecting motors, transformers, low-voltage distribution circuits, control equipment and metering systems. Its slim 17.5 mm modular width and DIN rail mounting arrangement help conserve valuable panel space while simplifying installation.

Compact Protection for Electrical Control Circuits
Cylindrical fuse holders provide a secure connection and accessible mounting point for replaceable fuse-links. When an overload or short circuit occurs, the installed fuse-link interrupts the current to help protect conductors, transformers, motors and connected control equipment.
The Mersen CMC81I combines compact dimensions with finger-safe protection and clear visual fuse-status indication. Its modular design allows multiple units to be installed side by side, while optional assembly accessories can be used to create coordinated multi-pole arrangements where required.
