Siemens Betagard Miniature Circuit Breaker (MCB), 4-Pole
– 5SP4491-7RC
The Siemens 5SP4491-7RC 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 projects, and OEM electrical panels where high current
handling and strong fault interruption capability are required.
This device comes in a 4-pole configuration (3P +
Neutral), making it suitable for three-phase distribution systems with
neutral protection. It uses a C-curve tripping characteristic, which
is ideal for circuits with moderate inrush currents such as feeders,
distribution boards, lighting circuits, and inductive loads.
With a rated current of 100A and a breaking
capacity of 10kA at 400V AC, it provides dependable short-circuit
protection and stable operation in demanding electrical environments.
