Industrial Lamp Module

The Schneider Electric ZB5AV3 is a 22 mm incandescent lamp module designed for 120 V AC control circuits. It mounts in standard push-button stations and provides clear visual indication for operators in industrial environments. The transformer-type module steps the supply down to a 6 V AC lamp for reliable service. It suits panel builders and maintenance teams who need a direct replacement in existing Harmony-style enclosures.

Panel Integration

The module uses screw-clamp terminals for secure wiring without special tools. Its plastic housing carries NEMA 1, 2, 3, 4, 4X, 12 and 13 ratings, allowing installation in indoor and outdoor enclosures that see dust, water spray or oil. The 22 mm cut-out matches common operator-interface layouts, freeing DIN-rail space for other components. No separate transformer is required, simplifying the bill of materials.

Sustained Operation

The incandescent lamp delivers steady light output as long as control power is present, with no flicker during voltage dips that can affect LED alternatives. Transformer isolation helps protect the lamp from line transients common in motor-start circuits. The module meets CSA C22.2 No. 14, UL 508 and IEC 60947-1, 60947-5-1, 60947-5-4 for continuous-duty applications. Builders who need higher efficacy or colour options should evaluate LED modules separately.

Questions about this item

How long will the 120 V AC incandescent lamp run continuously before the 22 mm transformer module reaches its thermal limit?

The module is built to NEMA 1, 2, 3, 4, 4X and 12, 13 ratings, so its enclosure handles sustained industrial duty without a published time limit.

What heat or noise does the transformer-type lamp module produce when powered all day?

The incandescent lamp generates noticeable warmth during continuous operation; the sealed plastic housing emits no audible noise.

Which operator head or mounting base must I already have to install this 22 mm lamp module?

It fits any 22 mm Schneider Electric Harmony push-button or pilot-light head that accepts a screw-clamp transformer module.
