Siemens Betagard Miniature Circuit Breaker (MCB), 4-Pole
– 5SP4480-7RC
The Siemens 5SP4480-7RC 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 switchboards, commercial
buildings, infrastructure installations, and OEM control panels where
dependable circuit protection and high breaking capacity are required.
This device comes in a 4-pole configuration, making
it suitable for three-phase systems with neutral protection. It features
a C-curve tripping characteristic, which is ideal for circuits with
moderate inrush currents such as distribution feeders, lighting systems,
socket outlets, 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 performance in demanding electrical environments.
