Additional Details

The AP12-1RC-72-302 circuit breaker uses hydraulic-magnetic technology, which provides stable trip characteristics regardless of ambient temperature variations. The 'AP12' indicates the series, which often dictates the physical size and mounting style. '1RC' likely refers to the number of poles and the type of terminals. The '72' is probably related to the current rating, which would be confirmed on the device's datasheet or label. The '302' might specify the trip curve or other unique characteristics of this specific model. The circuit breaker features a trip-free design, ensuring it will trip even if the handle is held in the 'on' position during an overcurrent event. Its sealed construction protects internal components from dust, moisture, and other contaminants, making it suitable for use in challenging environments. It is designed to meet various industry standards and certifications, ensuring compliance with safety regulations. Detailed specifications regarding voltage rating, interrupting capacity, and specific trip curve characteristics are available on the Sensata Technologies/Airpax website and associated datasheets.
