Why Choose the ABB S803S-UCB2 High-Performance MCB?
The ABB S803S-UCB2 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial electrical systems. As part of the ABB S800 high-performance MCB family, it combines robust construction with high interruption capability for applications requiring dependable circuit protection.
Featuring a 2 A rated current, Type B tripping characteristic and 50 kA short-circuit breaking capacity, the S803S-UCB2 provides sensitive protection for low-current circuits without the higher magnetic trip thresholds associated with characteristics intended for substantial inrush currents. Its three-pole construction enables coordinated switching and protection across three conductors.
The S803S-UCB2 uses ABB's established S800 platform to deliver compact, current-limiting circuit protection for industrial distribution and control applications. Its DIN-rail format supports straightforward installation in electrical panels, while the high breaking capacity makes it suitable for systems with substantial prospective short-circuit currents.
