Why Choose the ABB S802S-UCB32 Miniature Circuit Breaker?
The ABB S802S-UCB32 is a high-performance 2-pole miniature circuit breaker (MCB) specifically designed for the protection and control of DC circuits against overloads and short circuits. Part of the ABB S800S high-performance circuit breaker range, this UC-B version combines a Type B characteristic with high DC breaking performance for demanding commercial and industrial installations.
With a rated current of 32 A, a rated operational voltage of 500 V DC and a breaking capacity of 50 kA at 500 V DC, the S802S-UCB32 is engineered for applications where substantial prospective DC fault currents must be safely interrupted. Its UC-B characteristic provides dependable circuit protection while the 2-pole configuration enables both poles to participate in the DC interruption process.
The S802S-UCB32 is particularly suited to DC distribution, control systems and other professional applications requiring high breaking capacity. Its compact modular construction, IP20 protection and proven S800S platform make it a robust solution for integrating high-performance DC overcurrent protection into electrical assemblies.

High-Performance Protection for DC Distribution Systems
Direct-current circuits place particular demands on protective devices because a DC arc does not naturally pass through a zero-current point in the way an AC waveform does. The ABB S802S-UCB32 is engineered for DC applications and provides both overload and short-circuit protection while delivering the interruption performance required for high prospective DC fault currents.
With a 500 V DC operational rating and 50 kA ultimate and service short-circuit breaking capacities at that voltage, the S802S-UCB32 provides robust protection for demanding DC installations. Its 2-pole construction and S800S high-performance architecture make it suitable for professional distribution systems where dependable DC fault interruption is essential.
Typical Applications
- Industrial DC distribution systems.
- DC control and automation panels.
- Battery-backed electrical systems.
- DC auxiliary power circuits.
- Commercial and industrial DC installations.
- Electrical systems requiring high DC short-circuit breaking capacity.
