Additional Details

The AP17-1-51-802 circuit breaker utilizes hydraulic-magnetic technology, which provides consistent trip times even with changes in ambient temperature, unlike thermal circuit breakers. The 'AP17' likely indicates the series, determining the physical dimensions and mounting options. The '1' might represent the number of poles. The '51' could be related to the current rating, needing verification from the product datasheet or label. The '802' possibly defines the specific trip curve or other unique characteristics. It incorporates a trip-free mechanism, which ensures the circuit breaker will trip even if the handle is held in the 'on' position during a fault condition. Its high interrupting capacity allows it to safely interrupt high levels of fault current. The breaker is designed to meet RoHS compliance standards, making it free from hazardous substances. Detailed specifications, including voltage rating, exact current rating, and trip curve details, can be found on the Sensata Technologies/Airpax website and related documentation. This circuit breaker is essential for safeguarding electrical equipment and ensuring system reliability in diverse applications.
