Breaking capacity, often referred to as breaking or interrupting capacity, is a term used in electrical engineering to describe the maximum current that a circuit breaker or protective device can interrupt safely without being damaged or causing a hazardous situation. It is a crucial parameter for ensuring the reliable and safe operation of electrical systems. Key aspects of breaking capacity include: 1. **Ratings**: Breaking capacity is typically expressed in amperes (A) and can also be specified in terms of voltage level (e.g.
