30R185 Frequently Asked Questions (FAQs)

  • The recommended mounting torque for the 30R185 fuse is 0.5 Nm (5 in-lbs) to 1.5 Nm (10 in-lbs) as specified in the Littelfuse application notes.
  • While the 30R185 fuse is designed to withstand normal vibration, it's not recommended for high-vibration applications. For such applications, consider using fuses with specialized vibration-resistant designs, such as those with flexible leads or epoxy-filled bodies.
  • The 30R185 fuse is rated for operation up to 125°C (257°F). However, its melting I²t value may decrease at higher temperatures. Consult the datasheet and application notes for specific guidance on using the fuse in high-temperature environments.
  • The 30R185 fuse is designed for use up to 2,000 meters (6,562 feet) above sea level. For applications above this altitude, consult the datasheet and application notes for guidance on potential derating or alternative fuse selection.
  • Yes, the 30R185 can be used in DC circuits. However, the fuse's DC rating is typically lower than its AC rating. Consult the datasheet and application notes for specific guidance on using the fuse in DC circuits.
