3NA3803

The 3NA3803 fuse link from Siemens plays a critical role in protecting electrical circuits. It supports both AC and DC supply voltages, with specific ratings of 500 volts for AC and 250 volts for DC applications. Designed with an IP20 enclosure rating, it ensures moderate protection against physical contact. The unit operates with a minimal power loss of 1W, making it efficient for various uses. For installation, any mounting orientation is acceptable, though a vertical position is recommended for optimal performance.

The device is engineered to function effectively within a temperature range of -5 to +40 degrees Celsius. It can also withstand a maximum humidity of 80% relative humidity without condensation, which is crucial for maintaining reliability in varying environments. In terms of storage, the fuse link can be kept at the same humidity levels and can withstand altitudes up to 1000 meters above sea level without any derating. The recommended environment for the 3NA3803 is a clean indoor space, devoid of corrosive chemicals, ensuring longevity and performance integrity.
