What it represents
A gM fuse-link is a motor-circuit fuse with a characteristic chosen for starting and fault conditions. Its dual-rating notation must be recorded accurately, and the motor overload arrangement must be identified.
How to read it
- Read both ratings from the selected fuse-link documentation.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Record full dual rating
- Reference starting-current characteristic
- Identify overload relay
A distinction that matters
The two values in a gM marking are not two independently selectable continuous-current ratings.
