ABB 1SCA022698R1680 OFAF4AAM630 HRC Fuse Link

Description

• The ABB 1SCA022698R1680 is an HRC (High Rupturing Capacity) fuse link designed for use in electrical systems requiring protection against overcurrents. The specific designation "OFAF4AAM630" provides key information about its characteristics and intended applications.

• The "NH4a" in the designation indicates that this is a size NH4a fuse link. NH fuses are commonly used in low-voltage industrial applications to protect electrical systems and equipment. The "aM" specification further defines the type of operation; in this case, it stands for gG (general-purpose) and aM (motor protection). This means the fuse is suitable for general-purpose protection and motor protection applications.

• The "630" in the designation specifies the current rating of the fuse, indicating that it is designed to handle a current of 630 amperes. This current rating is crucial for ensuring that the fuse operates correctly under normal and fault conditions, protecting the connected equipment.
