Description
14 x 51 mm Cylindrical Fuse 400V AC 50A 120 kA Breaking Capacity Class aM
Features
- ? Engineered specifically as a Class aM (switchgear protection) partial-range fuse, this unit provides highly targeted short-circuit protection for motors and industrial switchgear. Unlike general-purpose gG/gL fuses that can blow prematurely under temporary electrical stresses, its time-delay characteristics effortlessly absorb the intense, momentary inrush currents typical of heavy machinery start-ups. This targeted functionality prevents unnecessary operational downtime and eliminates the costly labor and material expenses associated with replacing falsely cleared fuses
- Featuring an outstanding short-circuit interrupting rating of 120 kA at 400V AC, this industrial cartridge fuse delivers robust overcurrent containment for highly demanding automated systems and main distribution circuits. This massive breaking capacity ensures that severe faults are completely isolated before they can cause catastrophic damage to downstream motor starters, contactors, or control circuitry. Utilizing high-grade ceramic body material and silver-plated copper ferrule ends, the assembly offers superior structural integrity under thermal stress, effectively neutralizing high-energy arc faults.
- Built to standard European and international cylindrical dimensions (14.3 mm diameter by 51 mm length), this ferrule-style fuse is perfectly optimized for swift, tool-free installation into standard low-voltage distribution frameworks. It provides seamless drop-in compatibility with the Eaton Bussmann CH14 modular fuse holder series, including single-pole, multi-pole, and neutral-integrated configurations like the CH141DU and CH143DU. This precise dimensional compliance speeds up scheduled preventative maintenance cycles and panel modifications, eliminating physical installation headaches.
- With a low maximum power loss rating of just 2.9 Watts at nominal current, this low-voltage cartridge fuse runs highly efficiently to prevent excessive thermal buildup inside tightly packed control panels. Minimizing internal watt losses directly protects neighboring DIN-rail components and sensitive solid-state electronics from heat degradation. This sustained thermal management ensures reliable, long-term performance across continuous duty cycles while reducing the cooling load requirements of your industrial enclosure.
