Blue Sea 12V 15A Below-Deck Accessory Switch Panel with 1 SOC Feature and 2 USB Ports
Pre-Wired Harness - UV-Stabilised Face - Prevents Parasitic Draw

DESCRIPTION
Centralised 12V DC Power Distribution and Device Charging
Managing multiple onboard electronics and charging interfaces in a marine, caravan, or off-grid vehicle setup requires a clean, dependable power hub. The Blue Sea Systems 4365B Below-Deck Accessory Switch Panel consolidates 12V DC power delivery and device charging into a single, low-profile unit. Engineered specifically for 12V DC electrical architectures, this panel provides a dedicated control point for your auxiliary accessories while eliminating the clutter of individual inline fuses and loose wiring.
Eliminate Parasitic Battery Drain
One of the most common risks in mobile and marine 12V systems is parasitic current draw. Dedicated USB chargers and backlit sockets continuously consume small amounts of power even when no devices are connected, which can flatten a house or starter battery over time. This accessory panel resolves this issue by integrating an illuminated 15A circuit breaker switch directly into the faceplate. With a single flick of the switch, you can completely isolate the charging ports and socket when the vessel or vehicle is in storage, preserving your battery bank without needing to disconnect main battery terminals.
Engineered for Harsh Marine and Off-Grid Environments
Standard automotive switch panels often fail prematurely when exposed to coastal air, high humidity, or constant vibration. Constructed with a heavy-duty polycarbonate and ABS faceplate, the Blue Sea 4365B is fully UV-stabilised, flame-retardant, and impervious to corrosion. Whether installed in a boat cabin, a camper trailer kitchenette, or a 4WD canopy, it delivers reliable long-term performance.
- Integrated 15A Circuit Breaker: Combines switching and overcurrent protection into one illuminated rocker switch, removing the need for separate fuse blocks.
- Versatile Charging Layout: Features one 12V DC socket and two dual USB charger modules, allowing you to power 12V appliances and charge up to four USB devices simultaneously.
- Pre-Wired Harness Included: Supplied fully pre-wired from the factory to reduce installation time, minimise wiring errors, and ensure secure electrical terminations.
- Ingress Protection: Equipped with a silicone breaker boot, protective socket dust caps, and a rear mounting gasket to guard internal connections against dust and moisture ingress.
- Customisable Configuration: The modular design allows the 12V charging and monitoring ports to be swapped or upgraded in the future as your system requirements evolve.
Streamlined Installation and System Integration
Designed for straightforward below-deck or cabin mounting, this panel simplifies custom dashboards and electrical cabinetry. Because the rear harness is pre-assembled with marine-grade tinned wire, connecting the panel to your primary 12V DC positive bus and negative ground is fast and tidy. Please note that while the front face includes a sealing gasket and protective boots, this below-deck series is intended for sheltered cabin areas, consoles, or interior vehicle panels rather than direct, unprotected exposure to heavy deck washdowns.
Upgrade Your Onboard Power Control
