12-Way Blade Fuse Block W/Negative Bus – ATC/ATO Fuse Box Holder with Ground, LED Warning Indicator &Damp-Proof Cover Automotive Box Holder for Car Boat Marine RV Truck DC 12-24V

The Tawveml 12-Circuit Fuse Block Box is an exceptionally well-designed unit that delivers both functionality and safety. The construction quality stands out immediately — made from durable PBT and PC materials with nickel-plated copper terminals, it offers excellent conductivity and heat resistance. Installation is straightforward thanks to the clear layout and labelling system. The inclusion of both positive and negative terminals on each circuit keeps wiring organised and significantly reduces clutter. The LED warning indicators are a valuable safety feature, providing instant visual confirmation when a fuse has blown. This unit performs reliably under load, handling up to 30 amps per circuit and 100 amps total without issue. It’s ideal for automotive, marine, and off-grid electrical systems where performance and dependability matter. A professional-grade fuse distribution block that combines robust design, practical features, and peace of mind — highly recommended for anyone building or upgrading a 12V DC system.

Works as expected.

Decent little fuse box. Current detected on live side is due to the indicator circuit. This should allow voltage but next to no usable current

This is not an exciting component on the surface. But it is a structurally important one. Because once you move beyond basic wiring, you stop thinking in individual circuits and start thinking in distribution systems. And this is a distribution system. Organisation and structure The primary value here is consolidation. Instead of multiple inline fuses scattered through a loom, you get a single, centralised point of control. Twelve circuits in one place. Clearly separated. Clearly labelled. That immediately improves maintainability. Fault finding becomes significantly more efficient. Instead of tracing hidden inline holders, you can isolate circuits at a single access point. That reduces diagnostic time and removes ambiguity. Electrical clarity Each blade fuse slot provides a discrete protection point. That matters for safety and system integrity. If one circuit fails, it doesn’t cascade into others. It isolates the issue cleanly. The busbar design (on properly built units) ensures consistent feed distribution, avoiding voltage drop inconsistencies across multiple outputs. Build quality considerations The housing is typically polycarbonate or similar insulating material. That provides thermal resistance and mechanical stability. Terminal screws or spade connections need to be tight and secure—this is not an area for loose tolerances. Vibration resistance is important if this is used in automotive, marine, or mobile applications. A well-made unit will hold connections without gradual loosening under movement. Practical impact In real terms, this turns a wiring setup from “individual improvisation” into “structured system architecture.” You can expand, modify, and troubleshoot without dismantling the entire loom. That alone is a major operational improvement.

Nice compact board. Comes with two screws to mount it and a pack of various amp fuses. You will need to buy ring connectors and if you buy ring connectors make sure you have the proper crimping tool. (Update: ive brought another one) really impressed.

Very pleased,excellent quality

Blades missing

Love it easy to install on my boat nice tidy job and value for money

Habe den Sicherungshalter in meinen Lkw eingebaut. Da ich einige Led Lichter eingebaut habe hab ich vom Dauerplus und minus pol diesen Sicherungskasten dazwischen geschlossenen . Somit habe ich 12 Klemmen zum dazuschliesen. Und es sind einige Sticker als Beschriftung dabei . Und was mir am besten gefällt daran ist wenn eine Sicherung kaputt geht leuchtet eine Kontrolle Led . Somit muss man nicht erst alle Sicherungen raus und anschauen. Alles auf einen Blick und sehr gut und übersichtlich aufgebaut . Habe es auch schon in einige Lkw bei uns eingebaut . Dieser Sicherungskasten ist sehr zum empfehlen !!!!

Werkt perfect

Cumple bien su funcion

Excellent quality

Ik ben erg enthousiast over de UMISKY 12-Weg Zekeringhouder Box Zekeringkast en ik zou het zeker aanbevelen aan anderen. Deze zekeringhouder box is zeer eenvoudig te installeren en biedt een uitstekende bescherming voor de bedrading en elektronica in mijn boot. Het ontwerp van de zekeringhouder box is compact, waardoor het gemakkelijk is om het in een kleine ruimte te plaatsen. Het heeft 12 zekeringposities en is geschikt voor verschillende soorten zekeringen. Met handige leslampjes zodat in 1 oogopslag is te zien welke zekering stuk is. Het feit dat deze zekeringhouder box ook is uitgerust met een transparante hoes maakt het eenvoudig om de zekeringen te controleren en te vervangen als dat nodig is. Al met al ben ik zeer tevreden met de UMISKY 12-Weg Zekeringhouder Box Zekeringkast. Het is een geweldige aanvulling op mijn boot en ik zou het aan iedereen aanbevelen die op zoek is naar een betrouwbare en handige zekeringhouder box.
