Key Features:

  • Transparent housing allows instant visual verification of fuse condition
  • High interrupt rating (10,000A @ 14VDC) meets ABYC requirements for DC main circuit protection on large battery banks
  • Ignition-protected design (SAE J1171/ISO 8846) safe for installation in compartments with potentially explosive gases
  • IP66 sealed construction protects against dust and water intrusion in harsh marine and automotive environments
  • Color-coded for quick amperage identification
  • Shock and vibration resistant for demanding mobile applications
  • Wide voltage range supports 12V to 48V nominal systems (58 VDC rated)

Technical Specifications:

  • Continuous Current Rating: 30 Amps
  • Maximum Voltage: 58 VDC
  • Interrupt Rating @ 14 VDC: 10,000 Amps
  • Interrupt Rating @ 48 VDC: 5,000 Amps
  • Interrupt Rating @ 58 VDC: 2,000 Amps
  • Ingress Protection: IP66
  • Warranty: 4 Years

Protects electrical circuits from short circuit events and over-current loads, preventing wire insulation damage and ensuring long-term system reliability. Ideal for battery management systems, inverter protection, and main DC distribution circuits in marine vessels, RVs, and off-grid power systems.

I did not receive mounting hardware and had to buy my own. Chatted with customer service and they said they would inform the warehouse. Nothing happened.

Good price fast service

Need a taller Springfield plug-in post for pontoon boat to create a small grill table. You had the best price at the time . Item arrived and is a perfect fit. Very happy customers! Will consider your company for any further boat items.

Thank you fast service
