Schneider ZB5AV3 Light Block with BA9s Bulb, 110-120 V AC
Description
ZB5AV3: light block with body and fixing collar, BA9s incandescent bulb, 110-120 V AC
The ZB5AV3 is a Schneider Electric Harmony XB5 light block with body and fixing collar, listed in the datasheet as a complete body and light block assembly. It clips behind a 22 mm pilot light or illuminated head and carries the supply terminals. Seven Star LLC supplies the ZB5AV3 in Oman and the GCC as an independent supplier based in Muscat, usually to panel builders and maintenance stores.
The datasheet title reads “light block with body/fixing collar with BA9s incandesc. bulb 110–120V”. An incandescent version: a BA 9s bulb driven from an integral transformer rated 1.2 VA, 6 V, which takes a 110–120 V AC supply at 50/60 Hz.
Typical uses in Oman and the GCC
Light blocks sit behind pilot lights and illuminated heads on motor control centres, pump stations, switchgear doors and machine panels across oil and gas, petrochemical, power and desalination sites. The ZB5AV3 fits panels where the supply, heat and dust conditions suit the datasheet limits.
Lamp and transformer of ZB5AV3
The datasheet lists the light source as incandescent, with a BA 9s bulb base, and the light block supply as via integral transformer 1.2 VA 6 V. The block is rated for 110–120 V AC at 50/60 Hz, with steady signalling. The operating temperature is -40 to 55 °C, lower than the 70 °C of the LED blocks, a lower ceiling that the transformer-and-bulb design has to respect.
Net weight is 0.099 kg, noticeably heavier than the LED blocks, and the depth is 55 mm. Fit a bulb of the correct 6 V rating if the lamp has to be replaced.
Mounting and wiring of ZB5AV3
The block mounts from the front, clipping behind the head, and connects by screw clamp terminals: up to two conductors of 1.5 mm² with cable ends, or single conductors from 0.22 mm² without ends. The datasheet gives a tightening torque of 0.8 to 1.2 N.m and lists screw heads compatible with Philips and pozidriv No 1 drivers and flat 4 mm and 5.5 mm blades. The terminals are marked X1 and X2.
The datasheet specifies the panel hole as 22.5 mm recommended, with a finished-hole tolerance written as 22.3 mm plus 0.4 mm. For connection by screw clamp terminals or plug-in connectors it asks for a fixing centre of at least 40 × 30 mm, for Faston connectors 45 × 32 mm and for printed-circuit-board connection 30 × 30 mm. The cut-out data applies to the head that sits in front of this block.
Installation and maintenance notes
Clip the block behind the head, tighten the terminals to the specified torque and energise at the rated supply, then check that the lens glows evenly. Keep spares matched by voltage: the supply on the this unit label must agree with the circuit it is installed in. Re-check terminal tightness after the first thermal cycles on hot panels.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.
