BS 190/01 - Overvoltage protection, as fine protection for bus devices

## Product Overview The BS 190/01 module offers overvoltage protection, optimized as a fine protection layer for bus devices. ### Overvoltage Protection Characteristics 1. **Nominal Discharge Surge Current (8/20 µs):** Rated at 5 kA, this parameter defines the device's capacity to suppress transient overvoltages and protect sensitive downstream equipment. 2. **Voltage Protection Levels:** Core-to-core protection level is 750 V, while core-to-earth is maintained at 500 V, ensuring minimal residual voltage during surge events. ### Electrical Specifications 1. **Nominal Voltage DC:** Precisely engineered to operate at 24,000 V DC nominal, supporting high-voltage DC bus applications. 2. **Nominal Load Current:** Rated for 6 A continuous load, suitable for moderate current scenarios without thermal derating. ### Mechanical and Installation Details 1. **Mounting Method:** Designed for duct installation, facilitating modular assembly within electrical distribution systems. 2. **Degree of Protection:** IP20 rating ensures basic protection against solid foreign objects above 12 mm while lacking liquid ingress protection. 3. **Assembly Width:** Compact 12 mm width allows for efficient space utilization in panel assemblies. ### Connection and Safety Features 1. **Number of Conductors:** Configured for 2 conductors (excluding earthing), aligned with typical bus wiring schemes. 2. **Earthing:** Utilizes a separate conductor for earthing, maintaining electrical safety and electromagnetic compatibility. 3. **Remote Signalling Contact & Pro-active Thermo-Control:** Both features are absent, indicating reliance on external monitoring and passive thermal management. Leverage the BS 190/01 as a technically robust component for safeguarding bus devices against transient overvoltage conditions with precise electrical and mechanical integration capabilities.
