Schneider Electric ZB5AV04 Red Pilot Light Head,, BA9s

ZB5AV04: red pilot light head, plain lens, for BA9s bulb

The ZB5AV04 is a Schneider Electric Harmony XB5 pilot light head for a 22 mm panel hole, with a red plain lens in a dark grey plastic bezel. Seven Star LLC supplies the ZB5AV04 in Oman and the GCC as an independent supplier based in Muscat, usually to panel builders and maintenance stores finishing an XB5 indicator row.

The datasheet lists it as a head and basic element: it has no lamp or terminals of its own, and the light source is added through a separate block. The datasheet title reads “red pilot light head ø22 plain lens for ba9s bulb”. This head takes a BA 9s bulb, the classic miniature bayonet lamp. The red plain lens colours the light, and the bulb itself is replaceable from the front of the assembly.

Panel cut-out and mounting for ZB5AV04 and sealing

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. Pilot light heads do not usually need an anti-rotation plate, but the datasheet recommends one for selector switches and emergency stop heads fitted in the same hole pattern.

The datasheet lists protection of IP66, IP67, IP69, IP69K, an impact rating of IK05, and UL type 4X/13 enclosure use. The datasheet also quotes resistance to a high-pressure washer of 7000000 Pa at 55 °C from a distance of 0.1 m.

The datasheet gives -40 to 70 °C for both operation and storage, and the standard listed is IEC 60947-5-1. Approvals are not listed on the head datasheet, so any marine or UL requirement should be checked against the datasheet of the assembly as built.

Installation and maintenance notes

Fit the head in the 22.5 mm hole, secure it with the collar, and clip the matching light block behind it. Replace a failed BA 9s bulb by removing the head and fitting a new lamp of the correct voltage, and keep spare bulbs, which are the wear item of this design. Do a lamp test after commissioning to prove the ZB5AV04 lens colour and position agree with the panel legend.

Selection checklist and RFQ information for ZB5AV04

Send the points below so that the part number can be confirmed against the datasheet and checked for availability in one reply.

• Part number ZB5AV04 and the required quantity.
• The light block and supply voltage you plan to fit behind the head.
• Lens colour and meaning in your panel legend.
• Panel thickness and clearance behind the panel.
• Any approval needed by the project, compared with the datasheet.
• Delivery location in Oman or the GCC and the lead time you need.

Typical uses in Oman and the GCC

Pilot lights of this kind show status on motor control centres, pump stations, switchgear doors and machine panels across oil and gas, petrochemical, power and desalination sites. The this unit head gives a sealed lens suited to heat, dust and wash-down once the block is fitted behind it.

Colour and duty of ZB5AV04

Typical use is a fault or trip indication on an installation that already standardises on BA 9s lamps, or where a plain replaceable bulb is preferred to an integrated LED.

Red on a panel is normally reserved for faults, trips and danger, and the this unit should be assigned in line with the project colour table. The lens colour is red and the datasheet lists it as plain, with no marking.

Pilot light parts around ZB5AV04

A complete XB5 indicator is built from a head and a block. This lane contains two heads and seven light blocks, which together cover bulb and LED versions and several supplies.

Technical specifications of the ZB5AV04

Light block compatibility for this unit

The electrical composition codes in the datasheet are P3, P4, PF2. They describe front mounting with a BA 9s lamp, with and without a transformer for the supply, and a variant PF2 for front mounting with BA 9s. That is why the compatible light block is a separate part such as the ZB5AV3 listed in this lane, which carries a BA 9s incandescent bulb and an integral transformer.

Depth of the head alone is 31 mm, weight 0.018 kg.
