Why are specialty small physical sized fuses common in the commercial food service equipment industry?

In the commercial food service equipment industry, specialty small physical sized fuses are often common due to regulatory requirements set by UL codes and other safety standards. UL (Underwriters Laboratories) is an organization that develops safety standards for various products, including electrical equipment. These standards often specify that certain equipment must be designed with multiple protective devices, such as fuses, to ensure safety and prevent electrical hazards.

Using more fuses in designated physical spaces allows for improved circuit protection, as each fuse can handle different parts of the system and respond to faults independently. This not only helps in maintaining the integrity of the equipment but also aligns with safety regulations mandated by UL, thus making compliance easier for manufacturers.

Smaller fuses occupy less space, making it feasible to incorporate them into equipment without requiring significant redesign or excessively large enclosures. The compact size helps in maintaining the design, functionality, and efficiency of the equipment while ensuring that all safety requirements are met.
