Product Description

Product Description

1. Functional Differences

Model	Type	Key Features	Interlock Support
DXN-T	Basic Indicator	Only provides visual voltage indication (flashing light when live). No interlock or advanced functions.	No
DXN8-T	Enhanced Indicator	Supports visual indication and optional electromagnetic interlock (prevents access when live). Some models include self-test & voltage test ports812.	Optional
DXN8D-T	Smart Indicator	Adds self-check, voltage test, phase verification, and communication (RS485). Designed for intelligent switchgear with remote monitoring support15.	Yes (forced)

 

2. Technical Specifications

Parameter	DXN-T	DXN8-T	DXN8D-T
Rated Voltage	3-35kV	Up to 40.5kV	Up to 40.5kV
Interlock Output	No	Optional	Yes (forced)
Self-Check	No	Some models	Yes
Voltage Test	No	Some models	Yes
Communication	No	No	RS485 (optional)
Installation	Panel-mounted	Panel/embedded	Embedded

 

3. Application Scenarios

• DXN-T: Simple warning-only applications where only live indication is needed (e.g., older switchgear)1.

• DXN8-T: Standard switchgear & RMUs needing interlock safety (prevents door opening when live)12.

• DXN8D-T: Smart grids & modern switchgear requiring remote monitoring, self-diagnostics, and phase checks15.

 

Conclusion

• Need just a warning? → DXN-T

• Need interlock safety? → DXN8-T

• Need smart features? → DXN8D-T
