Contact us... Price & Availability This 3-pole breaker features a D tripping characteristic, making it ideal for circuits with high inrush currents, such as motor loads, transformers, and lighting systems. With a rated current of 10A and a breaking capacity of 10kA, it ensures robust protection under fault conditions. Built with ABB's renowned quality and precision, the S803N-D10 offers a rated operational voltage of 440V AC and is compliant with IEC/EN 60898-1 and IEC/EN 60947-2 standards. Its compact modular design allows for easy installation on standard DIN rails, while the clear visual indication and toggle mechanism provide straightforward operation and status monitoring. The breaker is designed for long service life and minimal maintenance, making it a cost-effective solution for demanding environments. This MCB is part of the S800 series, known for its high short-circuit breaking capacity and advanced current-limiting technology. The S803N-D10 is suitable for use in industrial automation panels, motor control centers, and power distribution systems. It is also compatible with a range of ABB accessories, including auxiliary contacts, shunt trips, and undervoltage releases, enhancing its versatility in complex electrical installations. The ABB S803N-D10 is a high-performance miniature circuit breaker (MCB) from the S800 series, designed for industrial and commercial applications where reliable overcurrent and short-circuit protection is critical. Basic Product Information Rated current of 10A and breaking capacity of 10kA (IEC/EN 60898-1) / 15kA (IEC/EN 60947-2) Rated operational voltage up to 440V AC Complies with IEC/EN 60898-1 and IEC/EN 60947-2 standards Compact modular design for DIN rail mounting High short-circuit breaking capacity with current-limiting technology Clear ON/OFF indication and padlockable toggle for safety Compatible with a wide range of ABB accessories (auxiliary contacts, shunt trips, undervoltage releases) 3-pole design with D-curve tripping characteristic for high inrush current applications Technical Specifications Version & Model Difference The S803N-D10 is part of the S800N series, which offers a breaking capacity of 10kA per IEC/EN 60898-1 and 15kA per IEC/EN 60947-2. There are also S800S and S800X variants with higher breaking capacities (up to 25kA and 50kA respectively) for more demanding applications. The D-curve version is specifically designed for circuits with high inrush currents, while B-curve and C-curve versions are available for residential and commercial applications. The S803N-D10 is the 3-pole version; 1-pole (S801N-D10) and 2-pole (S802N-D10) versions are also available. Application Scenarios What does the D-curve tripping characteristic mean? The D-curve means the breaker trips instantaneously at 10-20 times the rated current (In). This is ideal for circuits with high inrush currents, such as motors and transformers, to prevent nuisance tripping during startup. Is the S803N-D10 suitable for DC applications? No, the S803N-D10 is designed for AC applications only, with a rated operational voltage of 440V AC. For DC applications, ABB offers dedicated DC circuit breakers. Can I mount the S803N-D10 on a standard DIN rail? Yes, the S803N-D10 is designed for mounting on a 35mm DIN rail, which is standard in industrial and commercial electrical installations. What is the breaking capacity of the ABB S803N-D10? The S803N-D10 has a breaking capacity of 10kA according to IEC/EN 60898-1 and 15kA according to IEC/EN 60947-2, making it suitable for industrial applications.
