Siemens Betagard Miniature Circuit Breaker (MCB), 2-Pole
– 5SP4291-7RC
The Siemens 5SP4291-7RC 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 commonly used in industrial panels, commercial buildings,
infrastructure projects, and OEM applications where high current capacity
and dependable circuit protection are required.
This device comes in a 2-pole configuration, making
it suitable for single-phase (phase + neutral) or two-phase protection
systems. It features a C-curve tripping characteristic, which is
ideal for circuits with moderate inrush currents such as lighting circuits,
distribution feeders, socket outlets, and small inductive loads.
With a rated current of 100A and a breaking
capacity of 10kA at 400V AC, this MCB provides strong protection in
demanding industrial and commercial electrical environments.
