Background
Electrical fires are usually caused by rising residual current from insulation ageing and by overheating joints. Both develop slowly and show no visible symptom, so manual inspection almost never catches them.
How it works
Residual current transformers and temperature sensors are installed on distribution circuits, with a monitoring panel acquiring readings continuously and evaluating trend. A pre-warning is issued when values approach the limit and the linkage fires only at the alarm threshold — avoiding both nuisance trips and missed events.
Key capabilities
- Residual current alarm threshold adjustable 20 mA–1000 mA
- Four-channel cable temperature monitoring meeting GB 14287 accuracy requirements
- Two-stage warning: pre-alert first, alarm linkage second
- Data to cloud, with mobile viewing and historical trend retrieval
