- Boat, yacht and marine DC power‑distribution
Installation Warning
- This fuse is rated DC32V only, never apply voltage beyond specification.
- Fasten mounting bolts with proper torque; loose connection will result in abnormal overheating.
- Select fuse ampere rating slightly higher than equipment steady working current, avoid nuisance blowing from normal startup surge current.
- Always cut off power before replacing fuse. Install exact‑rating replacement fuse, do NOT use higher‑ampere substitute.
Custom & Packaging Options
- Silk‑screen: Standard print EssFuse and amperage rating; accept custom‑client logo. Please provide vector artwork for logo customization.
- Packaging: Bulk packing or color box packing are both available.
Preguntas frecuentes
Q1: What voltage does EssFuse‑0860 bolt‑on fuse support?
A1: EssFuse‑0860 series is rated for DC 32 Volt, it is designed for direct‑current heavy‑duty circuits for automotive, RV, marine and energy‑storage systems. Do not use for AC or higher‑voltage circuits.
Q2: Can I print my own brand logo on this 0860 fuse?
A2: Yes. Standard silk‑screen mark is EssFuse (START removed). Custom logo, part‑number and amperage printing are supported. Vector logo file required for custom order.
Q3: Are all amperage versions share same mounting dimension?
A3: Yes. 300A‑1000A fuses keep same outer mechanical size and mounting hole dimension. Only internal fuse element changes for different current ratings.
Q4: What material are the terminals and housing made of?
A4: The outer insulating shell is bakelite (phenolic resin, flame‑retardant). Conductive terminals are high‑purity red‑copper for low‑resistance and low temperature‑rise performance.
Q5: How to choose correct ampere rating for my RV / battery‑bank system?
A5: Choose fuse rating slightly higher than your system continuous working current, reserve margin for normal startup surge. Never pick excessive high amperage which loses circuit‑protection function.
Q6: What mounting torque should I apply for installation?
A6: Ensure firm bolt connection to avoid bad contact & overheating. Do not over‑torque to crack bakelite housing. Power must be disconnected during installation and replacement.
