Parallax Power Supply Fuse Blocks: Purpose-Built RV Circuit Protection
When it comes to managing the 12-volt DC electrical circuits in a recreational vehicle, few names carry the credibility of Parallax Power Supply. With more than 50 years of innovation in the RV electrical industry, Parallax approaches fuse block design the same way they approach every product — with a deep understanding of the demands that life on the road places on an electrical system.
A fuse block serves as the central hub of a vehicle's DC circuit protection strategy. Rather than relying on scattered, individual fuses, a quality fuse block consolidates multiple circuits into a single, organized panel. This not only makes wiring cleaner and more logical, but it significantly simplifies troubleshooting and maintenance when something goes wrong in the field.
The M036-7100-002: Parallax's 12V DC Fuse Block
The flagship Parallax fuse block in this category is the M036-7100-002, a 12-volt DC, 11-position board engineered specifically for use with Parallax's own 7100 and 7300 Series Power Centers. This design integration is a key differentiator — because the fuse block is purpose-matched to Parallax's converter and power center ecosystem, RV owners benefit from a seamless electrical architecture rather than a patchwork of mismatched components.
The unit consolidates multiple fused DC load circuits into one compact panel, making it an ideal solution for trailers, fifth wheels, and motorhomes where space is at a premium and circuit organization is critical. Multiple large non-fused input terminals accept heavier-gauge wiring from the battery, shore power converter, and tow vehicle charging leads, while individual fused output positions protect each downstream circuit.
Why Parallax Fuse Blocks Stand Out
Parallax's heritage traces back through companies like Phillips, BW Manufacturing, and MagneTek — giving them a depth of institutional knowledge that newer offshore manufacturers simply cannot replicate. Their products are built in North America using steel-based construction, consistent with how residential and industrial electrical systems are engineered. This commitment to material quality means the fuse block is built to withstand the vibration, temperature swings, and moisture exposure that RV environments routinely deliver.
Parallax also subjects its products to extensive cycle testing as part of their reliability promise, and the company's integration of innovative diagnostics into their broader power center lineup means the fuse block isn't working in isolation — it's part of a thoughtfully engineered system. For RV owners who already rely on a Parallax 7100 or 7300 Series Power Center, sourcing the matching Parallax fuse block ensures true electrical compatibility and simplifies any future service or replacement work.
- 12V DC rated for standard RV house battery and converter systems
- 11-position board accommodates a full range of DC circuit loads
- Designed for 7100 and 7300 Series Parallax Power Centers for seamless integration
- Heavy-gauge input terminals support multiple supply sources (battery, converter, tow vehicle)
- North American construction with a track record spanning 50+ years
Whether you're replacing a worn fuse board in an aging travel trailer or upgrading a power center installation, Parallax's approach to fuse block design reflects the same engineering discipline that has made them a trusted name across the RV industry.
