Description

BUSS MIDGET FUSE

Features

  • Standardized in the popular 10mm x 38mm (midget) footprint, this cartridge fuse is designed for precision fitment in dedicated fuse blocks, multi-pole holders, and disconnect switches. The compact ferrule design allows industrial engineers to save significant space within high-density control panels while maintaining robust circuit protection.
  • Featuring a specialized dual-element construction, this 20-amp fuse provides a critical "slow-blow" response that absorbs high initial inrush currents from small motors and inductive loads. By distinguishing between a harmless temporary surge and a dangerous sustained overload, it ensures continuous uptime for your HVAC equipment and industrial machinery without frequent, unnecessary replacements.
  • Built with a high-grade fiber tube body and nickel-plated brass endcaps, this fuse is engineered to withstand the thermal stresses of continuous operation in demanding electrical enclosures. The rugged construction ensures the fuse maintains its structural integrity and electrical characteristics even when subjected to the vibration and heat typical of manufacturing and commercial HVAC environments.
  • Listed as a "supplemental" overcurrent protection device, the FNM-20 is optimized to protect the individual components within a piece of equipment, such as control transformers or solenoids. By isolating faults at the device level, it prevents a single component failure from tripping the entire branch circuit breaker, allowing the rest of your facility's operations to continue uninterrupted.
