Electrical Characteristics:
The document outlines the electrical characteristics of a fuse designed for air conditioning systems, with a current rating range of 20A to 50A. The blowing time is specified as a minimum of 1 hour at 113% of the current rating and a maximum of 1 hour at 160% of the current rating.

Class of Operation:
The fuse operates under the class 'gR', which indicates its protective characteristics.

Interrupting Capacity:
The fuse has an interrupting capacity of 50,000 A at 500V AC (IEC standard), 50,000 A at 400V AC (UL standard), and 10,000 A at 250V AC.

Technical Parameters:
The document lists various part numbers with their corresponding current ratings and safety approvals. All parts from 20A to 40A have received safety approvals from CCC, TUV, and cURus, while the 50A part is pending approval.

Standards:
The fuse complies with standards IEC 60269-4, GB/T 13539.4, and UL 248-13.

Dimensions:
The dimensions are provided in millimeters, but specific measurements are not detailed in the summary.

Graphical Data:
An average I-T characteristics curve is referenced for informational purposes, indicating the relationship between current and time for the fuse's operation.
