Siemens Betagard Miniature Circuit Breaker (MCB), 3-Pole
– 5SP4380-7RC
The Siemens 5SP4380-7RC is a Betagard SENTRON
series miniature circuit breaker (MCB) designed for reliable protection of low-voltage
electrical distribution systems against overload and short-circuit
faults. It is widely used in industrial panels, commercial
installations, infrastructure projects, and OEM control systems where
dependable protection and high breaking capacity are required.
This device comes in a 3-pole configuration, making
it suitable for three-phase electrical distribution systems. It features
a C-curve tripping characteristic, which is ideal for circuits with
moderate inrush currents such as feeders, lighting systems, socket
distribution, and small inductive loads.
With a rated current of 80A and a breaking
capacity of 10kA at 400V AC, it provides strong short-circuit protection
and stable operation in demanding electrical environments.
