PRODUCT DESCRIPTION
ASEA BROWN BOVERI S203-D63 - Miniature Circuit Breaker
ASEA BROWN BOVERI S203-D63 is a three-pole Miniature Circuit Breaker from the S200 series, engineered for overcurrent protection in industrial and commercial electrical distribution systems. It integrates thermal-magnetic trip units to provide reliable short-circuit and overload protection, specifically designed for circuits with high inrush currents such as motors, transformers, and discharge lamps. This device ensures the integrity of electrical infrastructure and connected loads.
