Terminal Fuse Block 150A 58V DC Marine Rated Compact MRBF Fuse Block

Description

Product Overview

The JXJXQU Terminal Fuse Block 150A is engineered to deliver robust protection for DC power systems up to 58 volts. Constructed from high‑temperature ceramic, the fuse body resists corrosion and heat buildup, while the PPS thermoplastic seat adds structural stability. The ring terminal is tin‑plated, providing a reliable, low‑resistance connection that minimizes voltage drop and enhances safety. Designed for marine environments, the block meets stringent MRBF marine‑rated standards, ensuring it can withstand the harsh conditions of saltwater exposure, vibration, and temperature fluctuations. Its compact footprint—measuring just 2.43 x 2.43 x 1.83 inches—allows it to fit into tight engine bays, battery compartments, and control panels without sacrificing performance. The single stud (5/16″ M8) mounting simplifies installation, requiring only a standard bolt and a few minutes of work. With a current rating of 150 amps, the fuse block protects critical components such as inverters, windlasses, bow propellers, and charging stations from overloads and short circuits, extending the lifespan of expensive equipment and preventing costly downtime.

Usage

This fuse block is ideally suited for a wide range of applications where reliable DC protection is essential. In marine vessels, it safeguards the main battery bank, ensuring that propulsion and navigation systems remain operational even under heavy load conditions. Recreational vehicle (RV) owners benefit from its ability to protect auxiliary power systems, including lighting, HVAC, and entertainment units, from sudden surges that could damage sensitive electronics. The block also excels in new‑energy vehicles, where high‑current battery packs demand precise over‑current protection to maintain safety and efficiency. Industrial settings such as cranes, charging piles, and renewable energy installations (solar and wind) rely on the fuse block to prevent damage to power converters and control modules. Its easy‑install design means technicians can quickly replace a blown fuse without disassembling large sections of the system, reducing service time and labor costs. The product’s versatility makes it a go‑to solution for any DC system requiring a compact, durable, and marine‑grade fuse holder.

FAQ

What voltage range can this fuse block safely handle?

The block is rated for a maximum of 58 V DC, making it suitable for most marine, RV, and renewable‑energy battery systems that operate below this threshold.

Can the fuse block be used with batteries larger than 150 A?

Yes, the block is available in multiple current ratings (100 A, 150 A, 200 A, 250 A, 500 A). Choose the rating that matches your system’s maximum load to ensure proper protection.

Is the fuse block compatible with standard automotive battery terminals?

Absolutely. The 5/16″ (M8) stud size aligns with common automotive and marine battery terminals, allowing seamless integration without the need for adapters.

How do I replace a blown fuse in this block?

First, disconnect the power source. Then, using a standard fuse puller or needle‑nose pliers, remove the damaged fuse from the ceramic holder. Insert a new fuse of the same rating, ensuring it seats firmly. Reconnect the power and verify operation.

What warranty does JXJXQU offer for this product?

JXJXQU provides a one‑year limited warranty covering manufacturing defects. Our support team is available to assist with any installation or performance questions throughout the warranty period.
