£77.28
The ABB S403M-D16 is a high-performance 3-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in three-phase electrical systems. As part of the ABB S400M / SMISSLINE TP series, it combines a 16 A rated current, Type D tripping characteristic and 10 kA rated short-circuit breaking capacity with ABB's convenient plug-in distribution technology.
Designed for circuits with higher starting and inrush currents, the S403M-D16 uses a Type D characteristic suited to appropriately coordinated motors, transformers, auxiliary circuits and other inductive loads. Its three protected poles provide coordinated protection across three-phase circuits, making it particularly suitable for commercial and industrial installations.
With a 16 A rated current, 3-pole configuration and 400 V AC rated voltage, the S403M-D16 provides dependable protection for demanding three-phase applications. Its compact 54 mm width and SMISSLINE TP plug-in construction support efficient installation and straightforward integration into compatible ABB distribution assemblies.
Miniature circuit breakers such as the ABB S403M-D16 protect electrical conductors and connected equipment by automatically interrupting current when overload or short-circuit conditions occur. The Type D tripping characteristic accommodates higher momentary starting currents than Type B or Type C characteristics, helping reduce unwanted magnetic tripping when correctly selected for the connected load.
The S403M-D16 combines this specialised protection with ABB's SMISSLINE TP plug-in architecture. Its three-pole construction, 16 A rating and 10 kA breaking capacity make it a practical solution for demanding three-phase circuits requiring dependable protection, modular installation and straightforward system integration.
