ABB Inora 4 Gang 1 Way 10AX Switch Classic Grey BL104-G

Four gang means the unit contains four independent switch controls. One way means each connected circuit is operated from a single switching location rather than from two locations. The 10AX marking indicates a 10 A switch rating with additional suitability for certain lighting loads that can produce higher starting currents, subject to ABB specifications and the connected load design.

The four rockers can independently control separate lighting groups or other compatible switched circuits. Typical applications include controlling ceiling lights, wall lights, decorative lighting and outdoor lighting contactors from one point. The connected current, load type and switching arrangement must remain within the manufacturer's rating.

Yes, it is suitable for appropriately designed indoor electrical installations in UAE villas, apartments, offices, shops and other buildings. Compatibility must be confirmed against the project's supply voltage, wiring system, approved product schedule and the requirements of the relevant UAE utility or authority having jurisdiction.

It may be used to switch compatible LED lighting circuits, but the total driver load and, importantly, the LED drivers' inrush current must be checked. A circuit can draw a low running current while producing a much higher startup current. For large LED groups, an electrician may specify a suitably rated contactor or relay instead of switching the complete load directly.

No, the BL104-G is a one-way switch designed to control each circuit from one location. Lighting that must be operated from two points, such as at both ends of a corridor or at the top and bottom of a staircase, normally requires compatible two-way switches and the appropriate interconnecting wiring.

Installation should be completed by a licensed electrician with the circuit isolated, locked out where applicable and verified as de-energised. The electrician should confirm the back-box and wiring compatibility, identify the incoming live and four switched-live conductors, terminate them according to ABB's wiring diagram, secure the mechanism without trapping cables, fit the cover correctly and test polarity, insulation, continuity and operation before energising.

A conventional mechanical one-way switch generally interrupts the live conductor and does not normally require a neutral connection at the switch mechanism. However, the actual wiring arrangement must follow the ABB terminal markings, project drawings and local electrical regulations. Neutral conductors present in the box must be safely terminated and must never be connected to a switch terminal unless the manufacturer's instructions specifically require it.

Use a back box and mounting arrangement confirmed as compatible with the ABB Inora BL104-G dimensions and fixing pattern. Because four circuits may enter the box, adequate depth and cable capacity are important to prevent overcrowding, sharp cable bends or damaged insulation. Check the ABB technical documentation and project specifications before first-fix installation.

It should not be assumed to be weatherproof. For outdoor areas, bathrooms, wash zones, kitchens or dusty construction environments, verify the product's declared IP rating and the required installation zone. Where exposure to water, humidity or dust is possible, use an appropriately rated weatherproof enclosure or a purpose-designed outdoor switch in accordance with local requirements.

Do not select this lighting switch solely by comparing a load's normal current with the 10AX marking. Air conditioners, pumps, water heaters and motors can have high startup currents or require double-pole isolation and dedicated control equipment. Such loads should normally be controlled through correctly rated isolators, contactors or motor-control devices designed by a qualified electrical professional.

Contractors should verify the approved material submittal, ABB technical data, rated voltage and frequency, load type, prospective inrush current, back-box compatibility, cable size, terminal capacity, required IP rating and colour schedule. Installation must also comply with applicable UAE regulations, project specifications and the requirements of the relevant authority, such as DEWA or the applicable emirate utility.

A four-gang one-way switch is commonly installed where several lighting zones need independent control from one entrance point. Examples include villa living rooms, majlis areas, offices, retail units, meeting rooms and open-plan spaces. Combining four controls in one unit can provide a cleaner wall finish and simplify room-level lighting operation.

Isolate the electrical supply before inspection or maintenance. Clean the visible surface with a soft, dry or slightly damp cloth and avoid abrasive pads, solvents and excessive water. If a rocker becomes loose, discoloured, unusually warm, noisy or intermittent, stop using the affected circuit and have the wiring, terminals and connected load checked by a qualified electrician.

The BL104-G combines four independent one-way controls in a single coordinated accessory and provides a neutral Classic Grey finish suitable for many contemporary interiors. It is a practical option for residential and commercial lighting layouts where multiple circuits must be controlled from one location, provided the electrical rating and installation requirements match the project design.
