Industrial Lamp and Contact Block
This Schneider Electric module combines a transformer-type lamp unit with a single normally open contact block. It fits standard 22 mm panel cut-outs and operates on 110 to 120V AC supply voltage. The clear lens suits status indication where colour coding is not required. It is designed for use with B9 series control stations.
Sustained Load Behaviour
The incandescent lamp runs at 6V AC through the integrated transformer, reducing heat compared with direct mains types. The contact block carries a 10 A rating at 600V AC/DC and meets NEMA A600 and Q600 designations. NEMA type 1, 2, 3, 4, 4X and 12, 13 ratings together with IP66 ingress protection allow continuous operation in wet, dusty or outdoor environments.
Build and Mounting
The 22 mm threaded body secures with a locking nut for vibration-resistant panel mounting. Screw terminals accept solid or stranded wire for reliable field wiring. Compliance with UL 508, CSA C22.2 No. 14 and the EN/IEC 60947 series confirms suitability for industrial control panels. The unit does not suit applications needing coloured indication or multiple contact circuits.

Questions about this item
Does the ZB4BW031 generate noticeable heat or noise when powered continuously at 110 to 120V AC?
The incandescent lamp module runs on 6V AC via an internal transformer; it produces a small amount of warmth and no audible noise during all-day operation.
What existing hardware is required to mount and operate this 22 mm block?
It fits a standard 22 mm panel cut-out and is designed for use with Schneider Electric B9 lamp modules, so a compatible B9 base or enclosure must already be in place.
Will the 10 A, 600V AC/DC contact block rated A600/Q600 work reliably with legacy push-button stations?
Yes, the NEMA 1, 2, 3, 4, 4X, 12, 13 and IP66 ratings plus CSA 22.2 No. 14 and IEC 60947 compliance let it replace older blocks in the same panel footprint.
