Why Choose the ABB S803N-D16 High Performance MCB?
The ABB S803N-D16 is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. As part of the ABB S800N high-performance MCB range, it combines robust circuit protection with a compact DIN rail format and high short-circuit breaking capacity.
Featuring a 16 A rated current and Type D tripping characteristic, the S803N-D16 is particularly suited to circuits supplying equipment with high inrush currents. Its thermal and electromagnetic tripping mechanisms provide dependable overload and short-circuit protection while allowing the temporary starting currents associated with suitable motors, transformers and other inductive equipment.
The S803N-D16 provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC according to IEC/EN 60947-2. Its three-pole configuration, high breaking performance and robust construction make it suitable for industrial distribution boards, machinery and three-phase electrical systems where reliable protection against high prospective fault currents is required.

High-Performance Protection for High Inrush Loads
Miniature circuit breakers such as the ABB S803N-D16 automatically interrupt electrical circuits when excessive current occurs because of an overload or short circuit. Thermal protection responds to sustained overload conditions, while electromagnetic protection provides rapid interruption during high-current short-circuit faults, helping protect conductors, equipment and the wider electrical installation.
The Type D characteristic makes the S803N-D16 particularly suitable for circuits supplying equipment that can draw substantial current during starting or energisation. Combined with the high breaking capacity of the ABB S800N range, this makes the breaker suitable for demanding motor, transformer and industrial equipment circuits where reliable protection and tolerance of normal inrush currents are required.
