The Siemens 5SX23, part of their SENTRON series, serves as a miniature circuit breaker exceptionally suited for multiple applications. Equipped with three poles, it operates at a rated voltage of 400 V AC and a maximum current capacity of 63 Amps. The device has a breaking capacity of 6 kA when applied at 400 V AC, which ensures reliable protection and performance under fault conditions.
The rated insulation voltage is marked at 440 V AC, providing additional safety margins. This circuit breaker employs a DIN rail mount for easy installation, utilizing screw terminals for secure wiring connections. With an operational temperature range extending from -25 to +45 °C, it maintains functionality in various environmental conditions. For extended periods without use, the component can be stored at temperatures between -40 and +75 °C.
Operating under Trip Curve C allows the breaker to handle moderate overloads efficiently, making it suitable for many industrial applications. With a maximum relative humidity of 95%, it can endure reasonably humid environments. Protection class IP20 grants it limited protection against dust and accidental contact. Lastly, classified as Pollution Degree 3, it is tailored for environments that may have substantial contamination but are cleared for standard operation.
