The ABB S203-B6 is a three-pole miniature circuit breaker (MCB) from the industry-standard S200 series, featuring a "B" characteristic trip curve. This device is a compact, three-module MCB with a rated current of 6 Amperes per pole. The "B" curve is designed for the protection of circuits with very low inrush currents, providing fast and sensitive protection against short-circuits. It is the standard choice for circuits supplying purely resistive loads or loads with minimal startup surge, such as general lighting, socket outlets for small appliances, and certain control circuits.
