The S500 series heavy-duty circuit breaker is a low-voltage electrical protection equipment launched by ABB, designed to cope with the increasing short-circuit current in low-voltage power grids, with high safety, reliability, and breaking capacity. Its core function is to protect circuits, motors, equipment, and systems from the effects of overload and short-circuit currents through thermal and/or electromagnetic trip functions.

Installation and Dimensions
Installation method: S500 circuit breaker is designed for snap fit installation on standard 35mm rails.
Size: The size of products varies depending on the type and number of poles, for example, the 2-pole F502 series has a width of 75mm, the 3-pole F503 series has a width of 100mm, and the 4-pole F504 series has a width of 125mm.
Safety distance: There are specific safety distance requirements between grounding components, insulation covers or wiring pipelines, and exposed live parts.
