Overview

The ABB S803S-C25 is a 3-pole miniature circuit breaker (MCB) rated at 25A with a C-characteristic tripping curve, designed for overload and short-circuit protection in residential, commercial, and industrial applications. It handles moderate inrush currents typical of lighting circuits, small motors, and general-purpose wiring. The breaker offers a maximum breaking capacity of 50kA at 240/415V AC, ensuring reliable fault current interruption to protect downstream equipment. It supports operating voltages up to 400/690V AC and is suitable for DC applications, providing versatility across electrical systems. Key features include dual tripping mechanisms: a thermal element for overload protection and an electromagnetic element for short-circuit protection. The thermal mechanism responds to sustained overcurrents, while the electromagnetic mechanism provides instantaneous response to high fault currents, minimizing damage. The S803S-C25 complies with IEC/EN 60898-1 and IEC/EN 60947-2 standards, ensuring global compatibility and adherence to safety regulations. Cage terminals enable secure, tool-free conductor connections, reducing installation time and improving reliability. Designed for DIN rail mounting, the S803S-C25 integrates with ABB's SYSTEM PRO M compact range. It features a fast arc extinction system to minimize arcing during faults, enhancing safety and extending equipment lifespan. The breaker includes a contact position indicator (green OFF / red ON) and a trip position indicator (gray NO TRIP / orange TRIP) for easy status verification. It offers a mechanical endurance of 20,000 operations and an electrical endurance of 6,000 operations, ensuring long-term reliability in demanding environments. Approved for global use, the S803S-C25 meets international standards, including TN and IT systems. Its compact design supports a range of accessories—auxiliary contacts, shunt trips, and undervoltage releases—for customized configurations. Suitable for protecting lighting circuits, distribution boards, and industrial machinery, it delivers dependable performance and compliance with global electrical safety standards.
