Specifications:
The document outlines specifications for NH3LaBat and NH3LgBat fuses, rated for 1500V DC with current ratings ranging from 200A to 1400A. The fuses comply with IEC 60269-7 and UL 248-13 standards, ensuring high safety and performance.

Interrupting Capacity:
The fuses have an interrupting capacity of 150,000 amperes at 1500V DC, indicating their ability to safely interrupt high fault currents.

Technical Parameters:
The document lists various part numbers with corresponding current ratings from 200A to 550A. Each part number is marked with a safety approval status, denoted by a filled circle (●) for approved and an empty circle (○) for pending approval.

Dimensions:
The dimensions for the NH3LgBat type fuses are provided in millimeters, with specific measurements for different parts of the fuse. The class of operation is specified as gBat.

Average I-T Characteristics Curve:
An I-T (current-time) characteristics curve is included for reference, showing the relationship between current (in amperes) and time (in seconds) for various current ratings (200A to 550A). This curve helps in understanding the time it takes for the fuse to operate under different current conditions.
