NKK-A0051 14 Way DC Switch Panel with 1 Main and 13 Branch Circuits, Anodized Aluminum
The NKK-A0051 is a manually operated DC main distribution panel for boats: one main circuit feeds thirteen branch circuits, each with its own breaker, and fourteen green LEDs report switch status at a glance. The face plate is high intensity aluminium with an anodized finish, so it stays flat and corrosion free on a dash or bulkhead. Cabin appliances, deck equipment and lighting all land on one panel, with overcurrent and short circuit protection at the point of distribution.
NKK-A0051 At a Glance
- Configuration: 14 way panel, one main circuit plus thirteen branch outputs.
- Input: DC system, rated 12V DC, maximum input current 100A (optional rating).
- Breakers: main breaker DC50A (optional) and branch breakers at 10A / 15A / 20A / 25A (optional).
- Branch loading: up to 25A per branch (optional rating).
- Indication: one green LED at the input and thirteen green LEDs for the outputs.
- Protection: overcurrent and short circuit, for resistive and inductive loads.
- Face plate: high intensity aluminium, anodized.
- Mounting: flush mount with screws; W x H dimensions made to order.
- Customisation: silk screen circuit names, optional terminal board, optional backlight.
How the Panel Distributes Power
One feed in, thirteen circuits out. A single DC input lands on the main breaker, and the thirteen branch breakers take over from there, so each appliance or lighting group is isolated on its own switch instead of sharing one fuse.
Status is readable without a meter. The input LED shows the panel is live and the thirteen output LEDs show which branches are switched on, which shortens fault finding when a circuit drops out at night.
Breakers chosen to the load. Branch breakers are supplied at 10A, 15A, 20A or 25A depending on the circuit list, and the main breaker is normally DC50A, so protection matches the cable rather than a single compromise rating.
Built for a marine environment. Natural cooling, an anodized aluminium plate and an operating range of -25°C to 55°C suit engine rooms, lockers and helm consoles without a fan.

What the Panel Controls
- Cabin appliances: refrigeration, water pumps, ventilation and galley equipment.
- Vessel equipment: windlass, trim tabs, wipers and hydraulic control circuits.
- Lighting groups: navigation, deck, cabin and courtesy lighting on separate branches.
- RV and workboat builds requiring a fused DC distribution point with named circuits.
Installation Notes
- Prepare the circuit list first, including the breaker rating needed per branch, so the panel is built to that list.
- Confirm the panel W x H and the recess opening before cutting, because dimensions are made to order.
- Keep the input cable sized for the maximum input current and land it on the main breaker only.
- Leave natural ventilation around the housing and verify every LED after commissioning.

Buyer Questions
Q: How many circuits does NKK-A0051 provide?
Fourteen ways in total: one main circuit plus thirteen branch circuits, each with its own breaker and green LED.
Q: What are the breaker ratings?
The main breaker is normally DC50A and the branch breakers are supplied at 10A, 15A, 20A or 25A to match the circuit list; these are optional ratings confirmed at order.
Q: Does the panel protect against faults?
Yes, it provides overcurrent and short circuit protection and is rated for resistive and inductive loads.
Q: Is a backlight fitted?
Not as standard. Backlight and silk screen circuit names are available as customer options.
Q: Can the panel size be adapted?
Yes, the W x H dimensions are made to order, and the panel mounts flush with screws.
Q: What is the price basis?
Price is negotiable and depends on breaker ratings, dimensions, silk screen and the options selected.
