Mersen Modulostar CMC101 DIN Rail Cartridge Fuseholder 32A 690V 10.3x38.1mm

The Mersen Modulostar CMC101 is a compact, single-pole DIN rail mounting cartridge fuseholder designed for 10.3mm x 38.1mm fuse-links. Part of the highly reliable Modulostar range, it is constructed from robust and durable thermoplastic or thermoset materials, ensuring long-term performance in demanding electrical environments.

This modular fuse-holder adheres to strict safety standards, offering finger-safe protection to IP20 grade, even during fuse changes, which can be performed with a simple flick of a finger. Its space-saving, compact design makes it ideal for installations where panel space is at a premium. For multi-pole applications, units can be easily field-assembled using an optional pin-ties assembly kit.

Key Applications

Engineered for versatility, the CMC101 is suitable for protecting a wide array of circuits up to 690V AC/DC. Its typical uses include the protection of motors and transformers, low-voltage distribution systems, control circuits, drive protection, metering applications, and non-load operations. It is rigorously tested and approved for challenging environments, including marine and railway applications, where it meets specific shock and vibration requirements.
