Panel mount fuse holder for 6x30mm cartridge fuses adopts high‑temperature bakelite insulating base, built for reliable over‑current protection of low‑voltage AC‑DC systems. This 6×30 fuse base uses 0.4 mm phosphor‑bronze contact terminals, delivering stable contact performance, high‑grade arc‑suppression and excellent dielectric strength. M15*1.0 threaded panel‑mount construction allows quick front‑side fuse replacement without opening equipment housing. Widely deployed in industrial control cabinets, bench‑top power supplies, laboratory instruments and commercial appliance front panels.
Características principales del producto
- Compatible with standard 6×30 mm glass / ceramic cartridge fuses, covers mainstream medium‑power low‑voltage protection requirements
- Electrical rating: 10A, 250V / 125V AC/DC; 50A breaking capacity for safe fault‑current interruption
- Bakelite (phenolic resin) base, UL94 V‑0 flame‑retardant grade; superior heat‑resistance and arc‑quenching performance
- 0.4 mm thick phosphor bronze terminals, spring‑contact design, contact resistance below 5 mΩ
- 3000V AC power‑frequency withstand voltage; insulation resistance greater than 100 MΩ for high‑safety operation
- M15*1.0 metric thread panel‑mount, standard panel cut‑out dimension, easy assembly and maintenance

Guía de selección y solicitud
When selecting this bakelite panel mount fuse holder for 6×30 mm fuses, verify fuse dimension, system AC‑DC voltage and continuous operating current first. Select matching‑rating 6×30 glass/ceramic cartridge fuses and keep a 1.25‑1.5× safety margin to avoid over‑heating under continuous load. Prefer bakelite‑base variants for applications requiring enhanced arc‑suppression and high‑temperature resistance. Confirm M15*1.0 thread panel cut‑out matches drawing specifications to achieve secure installation and stable electrical contact. This threaded‑nut panel‑mount design enables front‑panel fuse replacement without taking equipment housing apart, which lowers field‑maintenance workload.
