ATEX Intrinsically Safe Battery NCR103443 Hazardous Area Power Solution
Powering electronic devices in hazardous areas requires more than performance—it requires controlled energy, fault tolerance, and intrinsic safety by design.
The NCR103443 intrinsically safe lithium battery is engineered as a hazardous area battery solution, supporting portable instruments and handheld terminals operating in explosive atmospheres.
This product follows ATEX and IECEx intrinsic safety design principles, making it suitable for integration into certified hazardous area equipment.
What Is an Intrinsically Safe ATEX Battery?
An intrinsically safe battery is designed to ensure that, even under fault conditions, the electrical and thermal energy released is insufficient to ignite flammable gases or dust.
This hazardous area battery is engineered to:
- Strictly limit voltage, current, and stored energy
- Control surface temperature and fault energy release
- Support compliance with IEC 60079-11 intrinsic safety concepts at system level
As a result, it serves as a reliable battery for hazardous area equipment, rather than a conventional high-energy lithium cell.
