Why Choose the Mersen CMC84 Modulostar® Fuse Holder?
The Mersen CMC84 is a compact and durable four-pole cylindrical fuse holder designed for dependable overcurrent protection in industrial control panels, machinery and low-voltage distribution systems. Part of the established Mersen Modulostar® CMC8 range, it accommodates standard 8 × 32 mm cylindrical fuse-links and provides coordinated protection for four-conductor electrical circuits.
The CMC84 features a modular, finger-safe construction with an IP20 degree of protection, including during routine fuse replacement. Its robust PA6 thermoplastic housing is engineered for demanding industrial environments, while the DIN rail mounting arrangement allows straightforward integration into control cabinets, switchboards and OEM equipment.
Rated at 25 A and 400 V AC, the Mersen CMC84 is suitable for protecting motors, transformers, control circuits, metering equipment and low-voltage distribution circuits. This standard version is supplied without a visual blown-fuse indicator, providing a reliable and economical solution where local fuse indication is not required.

Reliable Four-Pole Circuit Protection
The Mersen CMC84 securely houses four cylindrical fuse-links, helping protect electrical equipment against damaging overload and short-circuit currents. Its four-pole arrangement makes it suitable for multi-phase or multi-conductor applications that require coordinated fuse protection within a single modular assembly.
The compact DIN rail design supports efficient panel layouts, while the finger-safe housing helps minimise accidental contact with live components. Easy access to each fuse-link also simplifies routine inspection, maintenance and replacement by qualified electrical personnel.
