10 kA Breaking Capacity with C-Curve
With a 10 kA ultimate breaking capacity across 415 V AC and 440 V multi-phase systems, the 5SL4320-7RC Siemens miniature breaker ensures robust short-circuit protection. Its C-curve trip characteristic handles moderate inrush currents typical in lighting and socket circuits.
Voltage and Frequency Flexibility
The 5SL4320-7RC covers single-phase 250 V AC, multi-phase 440 V AC, and 50/60 Hz, allowing use across diverse grid standards without additional SKUs.
Wide Temperature Range and Material Integrity
Operational from -40 °C to 75 °C with halogen-free and silicon-free materials, this breaker suits extreme climates and sustainability goals.
DIN Rail Mounting with Sealable Option
The 18 mm width DIN rail design fits one modular unit, and sealable mounting prevents unauthorized access in commercial panels.
Active Status and Market Demand
The 5SL4320-7RC maintains active lifecycle status and high market demand, supporting reliable procurement for ongoing infrastructure projects.
