BG Nexus NBN53 13A Switched Fused Spur with LED Indicator & Flex Outlet – Double Pole - Black Nickel

BG Nexus Metal NBN53-01 Black Nickel 13A Switched Fused Connection Unit with LED & Flex Outlet

Create a premium fused connection point for a suitable fixed appliance or spur circuit with the BG Nexus Metal NBN53-01 Black Nickel 13A Switched Fused Connection Unit with LED Indicator and Flex Outlet.

Commonly searched for as a Black Nickel fused spur, switched fused spur, 13A FCU or appliance isolator, the NBN53-01 combines double-pole switching, fused protection, a visible power indicator and a front flex outlet in one decorative metal accessory. BG specifically describes the product as ideal for spur circuits and hard-wired power appliances.

Switched Fused Spur with LED Indicator

Unlike a basic switched fused spur, the NBN53-01 incorporates a power indicator. BG confirms Main Power Indicator: Yes, while the official FCU technical sheet describes Nxx53 products as having a flush LED power indicator.

This makes the product highly relevant to customer searches such as:

• Black Nickel fused spur with indicator
• fused spur with LED
• switched FCU with power light
• 13A fused connection unit with indicator
• appliance isolator with indicator
• double pole fused spur with LED

The indicator provides a clear visual feature on the faceplate for installations where a power-status indication is wanted.

Front Flex Outlet for Hard-Wired Equipment

A major difference between NBN53-01 and NBN50/NBN52 is the front flex outlet.

BG specifies:

• Flex Out: Yes
• Flex Out Position: Front Face
• Cable Outlet: Yes

The manufacturer also states that the flex outlet incorporates a removable blanking piece.

This makes NBN53-01 particularly relevant where a suitable appliance flex needs to leave directly through the face of the FCU rather than through a separate connection point.

Strong customer searches include fused spur with cable outlet, FCU with flex outlet, appliance fused spur with cable exit and switched fused connection unit with front flex outlet.

13A Double-Pole Switching

The NBN53-01 is rated 13A and uses double-pole switching. BG’s official technical sheet gives the full electrical rating as 13 Amp 250V AC and confirms the switch type as Double Pole.

For SEO, this gives strong relevance to:

• 13A double pole fused spur
• DP fused connection unit
• double pole appliance isolator
• 13A switched FCU
• 250V fused connection unit

Designed for Spur Circuits & Hard-Wired Appliances

BG explicitly describes the NBN53-01 as ideal for spur circuits and hard-wired power appliances.

Depending on the electrical design and appliance manufacturer's instructions, customer searches may include terms such as:

• boiler fused spur with indicator
• heating controls fused spur
• extractor fan fused spur
• kitchen appliance fused spur
• fixed appliance isolator
• hardwired appliance FCU

These are useful search-intent phrases, although suitability for a particular appliance must always match its installation requirements and circuit design.

Fused Connection Point

The accessory incorporates a dedicated fuse carrier, distinguishing it from a standard double-pole appliance switch. BG confirms that the NBN53-01 is fused, and the manufacturer's technical specification certifies the FCU range to BS 1363 Part 4.

Premium Black Nickel Finish

The NBN53-01 is finished in Black Nickel, creating a darker decorative appearance suitable for customers coordinating sockets, switches and fixed-appliance controls across contemporary interiors.

BG describes Nexus Metal products as having a sleek and slim premium-metal profile with softly rounded edges.

This makes the product especially relevant to searches for:

• Black Nickel electrical accessories
• premium dark metal fused spur
• designer appliance switch
• contemporary fused connection unit
• decorative Black Nickel FCU
• modern kitchen appliance switch

Colour-Coordinated Fuse Holder

BG identifies the fuse-holder colour as Black Nickel – RAL9004 (Signal Black) on the exact NBN53-01 product specification.

This helps maintain a coordinated dark appearance rather than introducing a contrasting white fuse carrier.

Angled Colour-Coded Terminals

BG equips NBN53-01 with angled terminals and confirms that the terminals have colour-coded printing, helping make identification and conductor access easier during installation.

Captive Backed-Out Terminal Screws

The exact product page confirms both captive terminal screws and backed-out terminal screws.

The combination is installer-friendly: backed-out screws leave the terminals ready for conductor insertion, while captive screws help prevent screws becoming separated from the accessory.

Twin Earth Terminals

The NBN53-01 provides two earth terminals. BG's wider FCU specification also highlights the Nexus Metal range's twin-earth arrangement.

Terminal Capacity

The current exact NBN53-01 product page lists:

3 × 2.5mm².

BG's official FCU technical sheet additionally gives the wider range terminal capacities as:

• 3 × 2.5mm²
• 2 × 4.0mm²
• 1 × 6.0mm²

For a SKU-specific Shopify specification, I would prioritise the 3 × 2.5mm² live-page figure and keep the broader technical-sheet capacities as supporting manufacturer information.

35mm Minimum Back Box Depth

BG specifies a 35mm minimum mounting-box depth, and this figure agrees between the current exact NBN53-01 page and official technical sheet.

This is an important buying specification because the combined switch, fuse carrier, indicator and flex-out mechanism requires more mounting depth than many simple light switches.

86 × 86 × 29mm Dimensions

BG’s technical drawing shows the Nxx53 configuration at approximately:

86mm high × 86mm wide × 29mm deep.

The manufacturer’s dimensions table independently confirms 8.6 × 8.6 × 2.9cm for N**53 products.

60.3mm Fixing Centres

The NBN53-01 uses 60.3mm fixing centres. BG also confirms that fixing screws are supplied.

Moisture-Control Gasket

BG incorporates a moisture-control gasket designed to protect the metal edges and help prevent tarnishing associated with new plaster.

This is particularly useful for decorative metal wiring accessories installed during renovation, extension and new-build work.

IP20 Indoor Rating

NBN53-01 is rated IP20, so it should be treated as an indoor wiring accessory rather than a weatherproof exterior fused spur.

BS 1363 Part 4

BG certifies the Nexus Metal FCU range to BS 1363 Part 4. The official technical specification additionally lists:

• 13A 250V AC
• Double-pole switching
• Intertek licence 1015
