The Siemens 8WN4420-0GA00 is a buzzer element for the Siemens 8WN44 signalling-column system, designed to provide a continuous audible sound for industrial warning and status-signalling applications. The exact article operates at 24 V AC/DC and is designed for the 70 mm diameter modular signalling-column system. Siemens product documentation identifies 8WN4420-0GA00 as the 24 V AC/DC continuous-tone buzzer element.
For SB Smart, this product is positioned as a Siemens industrial signalling component for machine alarms, warning indication, control panels, switchboards, equipment status signalling, maintenance and replacement requirements.
The 8WN4420-0GA00 belongs to Siemens' 8WN44 signalling-column family, which uses modular elements with a 70 mm diameter. The system supports combinations of audible buzzer elements and LED light elements, with up to five elements mountable in one signalling column. Siemens documentation also specifies a thermoplastic enclosure and IP65 degree of protection for the 8WN44 system.
The exact article is the continuous-tone buzzer version for 24 V AC/DC.
The 8WN4420-0GA00 is designed for 24 V AC/DC operation. Current product data confirms the auxiliary supply as 24 V AC/DC.
The control voltage should be matched with the actual signalling circuit before installation.
The defining feature of the 8WN4420-0GA00 is its continuous audible tone. Siemens lists it under the continuous-tone buzzer category.
A continuous sound is useful when an alarm or operating condition needs to remain audible for as long as the buzzer is energized.
For applications requiring an intermittent alarm, Siemens provides the corresponding 8WN4420-0HA00 pulsating-tone version.
The 8WN4420-0GA00 is designed for the Siemens 8WN44 modular signalling-column system with a 70 mm diameter.
This standardized format allows the buzzer to be assembled with compatible light elements and mounting accessories.
The Siemens 8WN44 signalling-column system is specified with an IP65 degree of protection.
This makes the system suitable for many industrial signalling environments requiring protection against dust and water jets, provided the complete assembly is correctly installed.
The 8WN44 signalling-column system uses a thermoplastic enclosure. Current product listings also identify the buzzer as having a thermoplastic enclosure and a black colour.
This provides a compact housing for the audible signalling element.
The 8WN4420-0GA00 is a buzzer element, rather than a complete signalling column.
It can be combined with compatible:
Continuous LED light elements
Blinking LED light elements
Other signalling components
Connection elements
Covers
Mounting accessories
Siemens specifies that up to five elements can be mounted in the 8WN44 modular signalling system.
The buzzer can provide continuous audible notification for conditions such as:
Equipment alarms
Fault indication
Machine warnings
Operator attention
Process notifications
Electrical-panel alarms
Industrial equipment status
The actual alarm logic is determined by the control circuit connected to the buzzer.
The 8WN4420-0GA00 can be considered for compatible applications such as:
Industrial control panels
Electrical switchboards
Machine panels
Factory signalling systems
Equipment warning systems
Industrial machinery
Process indication systems
Maintenance and replacement installations
Its continuous tone is suitable where a steady audible warning is required.
Within the Siemens 8WN44 range, the buzzer is available in different sound types:
8WN4420-0GA00: Continuous tone, 24 V AC/DC
8WN4420-0HA00: Pulsating tone, 24 V AC/DC
For continuous audible signalling at 24 V AC/DC, the 0GA00 version is the appropriate article.
The 8WN44 modular system also includes LED light elements in several colours. For 24 V AC/DC continuous light, Siemens lists:
8WN4420-5AB00 – Red
8WN4420-5AC00 – Green
8WN4420-5AD00 – Yellow
8WN4420-5AE00 – Clear
8WN4420-5AF00 – Blue
Blinking-light versions are also available for the same 24 V AC/DC system.
Siemens lists compatible 8WN44 accessories including:
8WN4408-0AF00 – Connection element
8WN4408-0AG00 – Cover
8WN4408-0DH00 – Foot with 60 mm pipe
8WN4408-0DJ00 – Foot with 80 mm pipe
8WN4408-0DA00 – Foot with 110 mm pipe
8WN4408-0CC00 – Bracket for wall mounting
8WN4408-0CF00 – Mounting with feet and pipe
8WN4408-0CG00 – Fold-out support/pivoting base
The correct accessories depend on the desired signalling-column installation.
The 8WN4420-0GA00 can be used when an existing Siemens 8WN44 signalling column requires replacement of its 24 V AC/DC continuous-tone buzzer element.
Before ordering, verify:
8WN44 system compatibility
Supply voltage
Continuous or pulsating sound requirement
Signalling-column diameter
Existing connection arrangement
Mounting accessories
This helps avoid selecting the visually similar pulsating-tone 8WN4420-0HA00.
Siemens lists the 8WN44 continuous-tone buzzer family as:
8WN4420-0GA00 – 24 V AC/DC
8WN4440-0GA00 – 110 V AC/DC
8WN4450-0GA00 – 220 V AC
The operating voltage should always be matched to the signalling circuit.
Siemens selection and ordering data specifies a standard package quantity of 1 unit for 8WN4420-0GA00.
This makes the product suitable for individual replacement and maintenance procurement.
Current product information identifies 8WN4420-0GA00 as an active Siemens product (PLM PM300: Active Product).
Availability and lead times can vary by supplier and location.
Current Indian product data lists approximate packaged dimensions around 80 mm × 80 mm × 85 mm. Another marketplace listing gives approximately 70 mm diameter, consistent with the 8WN44 system. Exact mechanical dimensions should be taken from the Siemens drawing when panel clearances are critical.
The Siemens 8WN4420-0GA00 is relevant for:
Electrical panel builders
Industrial buyers
Maintenance departments
Electrical contractors
Machine builders
OEM maintenance teams
Electrical product dealers
Replacement-part procurement
