5SP4280-7

The Siemens 5SP4280-7 is a heavy-duty miniature circuit breaker (MCB) engineered for two-pole protection in high-load electrical systems. It operates at 400 V AC and provides a robust short-circuit breaking capacity of 10 kA. With a Type C tripping characteristic and a rated current of 80 A, this MCB is designed for circuits with moderate inrush currents, such as inductive loads. Its compact 70 mm depth allows easy integration into modern, space-efficient distribution panels.
