Inline Fuse Holder — Waterproof Replaceable Inline Fuse Holder
The Rich Solar Inline Fuse Holder adds single-circuit overcurrent protection to any DC solar wiring run — sealed against moisture and dust at IP67, rated for 1000V DC, and available with a replaceable 10A, 15A, 20A, or 30A fuse to match your panel and wiring setup. Solar connector leads on each end with auto-lock male and female points make installation a simple plug-and-play addition to your existing array wiring, protecting panels, charge controllers, and downstream components from damaging overcurrent events.
Replaceable Fuse — No Need to Replace the Whole Unit
If the fuse blows from an overcurrent event, simply replace the internal fuse element rather than the entire holder and connector assembly — a meaningful cost and convenience advantage over fixed-fuse inline protectors.
IP67 Waterproof for Any Outdoor Wiring Run
Fully sealed against moisture and dust ingress — suitable for installation anywhere along an exposed solar wiring run, including rooftop junctions, ground-mount cable routing, and marine deck installations.
Plug-and-Play Solar Connectors
Auto-locking male and female connector leads on each end integrate directly into standard solar connector wiring — no splicing, soldering, or additional hardware required to add this protection point into your existing array.
Product Overview
The Rich Solar Inline Fuse Holder is a single-circuit overcurrent protection device designed to sit directly in a DC solar wiring run between a panel (or group of panels) and the rest of the system. It uses standard solar connector leads on each end with auto-locking male and female contact points, so it installs the same way any other inline solar connector does — no cutting, splicing, or soldering required to add it to an existing array.
The holder is available with a 10A, 15A, 20A, or 30A fuse depending on the current rating you need for your specific circuit — choose based on your panel's rated current, your wiring gauge's ampacity, and your charge controller's input limits. If the fuse blows due to an overcurrent fault, it can be replaced on its own; the housing and connector leads don't need to be discarded along with a single blown fuse, which keeps ongoing maintenance costs low compared to a fixed, non-replaceable inline fuse.
Built for outdoor solar applications, the holder carries an IP67 waterproof rating and an IP2X rating for dust and finger-touch protection on the connector interface. The 1000V DC rated voltage, CAT III overvoltage category, and UL94-V0 flame-retardant PPO housing reflect a design intended for the demanding electrical environment of a permanently installed solar array rather than a general-purpose automotive or low-voltage fuse holder. Copper, silver-plated contacts and a low 1mΩ contact resistance keep voltage drop across the connection minimal, preserving more of your system's available power.
Why a Solar Array Needs Inline Fuse Protection
- Prevents Overcurrent Damage: Protects panels, wiring, and downstream charge controllers from damage caused by excessive current — whether from a wiring fault, a short circuit, or an unexpected surge condition.
- Complete Single-Circuit Protection: Designed to protect one specific circuit branch in your array — pair multiple fuse holders with parallel-wired panel branches for protection at each connection point.
- High Current-Carrying Capacity: Rated to handle the full operating current of its rated amperage without excess heat buildup or premature failure under normal conditions.
- Standard Practice for Parallel Wiring: When combining multiple panels in parallel, individual branch fusing is a widely recommended safety practice — this holder provides that protection without custom fuse panel fabrication.
- Protection Class II Rated: Double-insulated construction provides an added layer of electrical safety beyond basic single-insulation designs.
Replace the Fuse, Not the Whole Unit
- User-Replaceable Fuse Element: If the fuse blows, open the holder and swap in a new fuse of the same rating — no need to purchase and re-wire an entirely new inline connector.
- Lower Long-Term Cost: A single spare fuse costs a fraction of a full replacement fuse holder assembly — keep a few spares on hand for fast field repairs.
- Faster Troubleshooting: A blown fuse is often the first thing to check when a panel circuit stops producing — having a replaceable design means diagnosis and repair happen in the field without ordering a new part.
- Compatible with PV Cables of Varying Insulation Diameters: The holder accommodates different PV cable insulation thicknesses, giving flexibility across a range of common solar wire gauges and brands.
- Touch-and-Insertion Reed Connector Design: Inner-knob style contacts provide a secure mechanical and electrical connection that resists loosening from vibration in mobile installations.
Built for the Outdoor Electrical Environment
- IP67 Waterproof Rating: Fully sealed against water immersion and dust ingress — appropriate for rooftop, ground-mount, marine, and any other exposed outdoor wiring location.
- UL94-V0 Flame-Retardant PPO Housing: Self-extinguishing plastic housing rated to the highest UL94 flammability classification, reducing fire risk in the event of an internal fault.
- 6000V Test Voltage (50Hz, 1 min): Insulation tested well beyond its 1000V DC rated voltage, providing significant safety margin against insulation breakdown.
- CAT III Overvoltage Category: Rated for the overvoltage transient environment typical of fixed installation wiring — appropriate for permanently installed solar circuits.
- Wide Operating Range, -40°F to +257°F: Functions reliably from arctic cold to extreme heat — covering the full range of conditions a permanently installed outdoor fuse holder will encounter.
Drop-In Installation, No Special Tools
- Solar Connector Leads on Each End: Male and female solar connector leads integrate directly into standard solar wiring — splice it into an existing run or build it into a new array from the start.
- Auto-Lock Connection: Male and female connector points lock automatically on insertion, providing a secure, reliable connection without additional clips or fasteners.
- ≤50N Insertion / ≥50N Withdrawal Force: Easy enough to connect by hand during installation, but secure enough to resist accidental disconnection from vibration or cable tension during regular use.
- Designed for a Wide Range of DC Applications: While built for solar, the connector and protection format suits other DC wiring applications using compatible solar-style connectors.
- No Splicing or Soldering Required: The plug-and-play design means most installations take minutes — disconnect the existing connector pair, insert the fuse holder in between, and reconnect.
