ABB Inora 4 Gang 1 Way 10AX Switch White BL104

Isolate the electrical supply before inspection or maintenance. Clean the white faceplate with a soft, dry or lightly damp cloth and avoid abrasive cleaners, solvents or direct water spray. If a gang feels loose, becomes unusually warm, crackles, discolours or operates intermittently, stop using it and have the wiring and switch inspected by a qualified electrician.

The electrician should confirm secure terminations, correct circuit identification, proper faceplate alignment and independent operation of all four gangs. Required electrical tests should be completed and recorded, including continuity, insulation resistance, polarity and operation of the relevant protective devices. Each gang should also be labelled where the controlled circuit is not obvious, particularly in commercial or multi-room installations.

Yes, its four independent controls and 86 x 86 mm format can make it suitable for villas, apartments, offices, shops and other UAE fit-out projects where several circuits need to be grouped at one point. For renovations, verify existing back-box dimensions, conductor identification and available depth. For new construction, include the switch type, finish, load schedule and mounting requirements in the approved electrical material submittal.

Cable size and protective-device rating must be determined from the circuit design rather than from the switch rating alone. The electrician or engineer should consider connected load, installation method, ambient temperature, grouping, voltage drop, fault protection and local authority requirements. The circuit protective device must protect the wiring and accessories, and it must not permit the switch to be overloaded.

It may be installed in dry indoor areas when permitted by the electrical design. Bathrooms, kitchens, balconies, gardens and external locations require additional consideration for moisture, splashing, dust and installation zones. No IP rating is provided in the available specifications, so it should not be treated as weatherproof. Use an appropriately IP-rated enclosure or a purpose-built weatherproof switch and follow UAE regulations for wet or outdoor locations.

It may be used with compatible LED lighting when the total operating current and, importantly, the LED driver inrush current remain within the switch manufacturer’s permitted limits. Multiple LED drivers can create a brief startup current much higher than their combined wattage suggests. For large lighting groups in villas, offices or retail projects, use an engineer-specified contactor or relay rather than switching the load directly.

The product name identifies the BL104 as a 4 gang, 1 way, 10A switch, while some supplementary listing text mentions wireless and touch-screen features. Because these descriptions are inconsistent, buyers requiring Wi-Fi, mobile-app control, touch operation or smart-home compatibility should confirm the exact functions and product image with FEPY before ordering. Do not assume that a neutral connection, hub, app or wireless protocol is included unless explicitly verified.

A conventional mechanical one-way switch normally switches the live conductor and may not require a neutral at the switch position. However, the listing also contains references to smart, illuminated and wireless functions that are not fully confirmed by the core model details. Check the terminal layout and supplied ABB instructions before wiring, because electronic or illuminated versions may have different conductor requirements.

The switch has an approximately 86 x 86 mm front profile and a listed overall depth of 37.1 mm. Before ordering for a construction or refurbishment project, confirm that the selected flush or surface box matches the mounting pattern and provides sufficient internal depth for terminals, conductors and safe cable bending. A deeper box may be advisable where multiple cables or loop-in connections are present.

Installation should be completed by a licensed electrician. The supply must be isolated at the distribution board, locked out where required and proven dead with an approved tester. The electrician should identify the permanent live feed and four switched-live conductors, connect them according to the terminal markings and ABB instructions, secure the mechanism in a compatible wall box, fit the faceplate and test polarity, insulation, earth continuity and switching operation before energising.

The stated switch rating is 10A, but usable capacity must be confirmed from the product markings and ABB documentation. Load type matters: LED drivers, fluorescent fittings, fans and other inductive or capacitive equipment can produce high starting or inrush currents even when their normal current is low. An electrician should calculate the connected load and use a correctly rated relay or contactor where necessary.

The switch is primarily suited to independently controlling lighting circuits and appropriately rated fans or similar fixed loads. Typical applications include bedrooms, living rooms, offices, shops, kitchens, corridors and other areas where several circuits meet at one control point. Do not use it for socket outlets, heavy appliances, water heaters, air conditioners or motors unless the circuit design uses a suitable contactor or relay and has been approved by a qualified electrical engineer.

It can be suitable for typical UAE low-voltage installations when selected and installed correctly for the circuit. UAE buildings generally use a 230V, 50Hz single-phase supply, but suitability depends on the load, wiring method, protective device and project specifications. Installation should comply with applicable UAE authority requirements, relevant BS/IEC practices and local regulations from bodies such as DEWA, ADDC or the authority having jurisdiction.

It’s a wireless smart 4‑gang wall switch (Inora BL104) with illuminated white touch switches. Each gang can control a separate load, giving you smart control over multiple lights or devices from a single plate.
