Siemens ED43S125A is a molded case circuit breaker from the Sentron Series designed for providing a main disconnect and short-circuit protection in three-phase industrial power distribution systems. It features a 125A continuous current rating and a 480V AC voltage rating, with a robust 18kA interrupting capacity at that voltage. The unit is constructed with a compact ED frame, measures 170mm x 150mm x 101mm (6.693" x 5.906" x 3.980"), weighs 3.781 lb, and utilizes a three-pole, bolt-on connection. It is certified to UL and IEC standards and operates reliably within a temperature range of -25°C to 70°C (-13°F to 158°F). This non-automatic, instantaneous-trip circuit breaker is typically applied in panelboards, switchboards, and industrial control panels where dedicated short-circuit protection is required without thermal overload functionality.
