Reliable Protection for Three-Phase Circuits
Cylindrical fuse holders provide a secure mounting and connection point for fuse-links used to protect electrical equipment against overloads and short circuits. When installed with a correctly selected 22 × 58 mm fuse-link, the CMS223 helps isolate a faulty circuit before excessive current can damage cables, machinery or other electrical components.
The three-pole design makes the CMS223 particularly suitable for three-phase systems where each phase requires individual fuse protection. Its modular construction and DIN rail mounting arrangement allow it to be incorporated efficiently into industrial control cabinets, distribution boards and machine control systems.
