Why Choose the Mersen CMS221I Modulostar® Fuse Holder?
The Mersen CMS221I, manufacturer item number B331086, is a compact single-pole modular cylindrical fuse holder designed for 22 × 58 mm fuse links. Part of the Mersen Modulostar® CMS22 series, it provides dependable overcurrent protection for industrial control panels, electrical distribution equipment and machinery.
The CMS221I includes an integrated visual blown fuse indicator, helping maintenance personnel identify an operated fuse quickly while power remains available to the indication circuit. This can reduce fault-finding time and simplify servicing in panels containing multiple protected circuits.
Rated at 125 A and up to 690 V AC or 690 V DC under IEC ratings, the CMS221I is suitable for demanding industrial electrical systems. Its IP20 finger-safe construction helps protect against accidental contact with live components, including during normal fuse replacement.
Key Advantages
- Single-pole modular fuse holder for 22 × 58 mm cylindrical fuse links.
- Integrated visual blown fuse indicator for faster fault identification.
- 125 A current rating for demanding industrial circuits.
- Rated for up to 690 V AC and 690 V DC.
- IP20 finger-safe construction under applicable IEC requirements.
- Compact modular format helps conserve control-panel space.

Reliable Protection with Visual Fuse Indication
The CMS221I securely accommodates a 22 × 58 mm cylindrical fuse link, providing a convenient connection between the fuse and the protected circuit. When excessive current or a short circuit occurs, the correctly selected fuse link interrupts the supply to help protect cables, machinery and electrical equipment.
Its integrated visual indicator makes it easier to locate an operated fuse within a busy control panel. Combined with finger-safe construction and DIN rail mounting, this makes the CMS221I well suited to professional panel-building and industrial maintenance applications.
