Why Choose the ABB S803S-UCB25-R High Performance MCB?
The ABB S803S-UCB25-R is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800 high-performance circuit breaker family, it combines a rated current of 25 A, a B tripping characteristic and high short-circuit breaking capability for industrial, commercial and infrastructure applications.
The S803S-UCB25-R provides thermal protection against sustained overload conditions together with electromagnetic protection for rapid interruption of short-circuit currents. Its B characteristic is suited to circuits where the expected inrush current is relatively low, providing sensitive and dependable protection for suitable resistive and general electrical loads.
With a three-pole configuration, 25 A rated current and 50 kA breaking capacity, the S803S-UCB25-R is designed for electrical systems where significantly higher fault-current performance is required than that offered by conventional miniature circuit breakers. ABB order code 2CCS863002R1255 identifies this specific S800-series high-performance protection device.
