Visual Inspection Guide for Loading Spring and VCB Contact Wear Indicator
LS Electric ACB Maintenance Manual – Visual Inspection of Loading Spring
The VCB Contact Wear Indicator is mentioned in the user manual. The loading spring pressure can be visually inspected to determine the condition of the circuit breaker’s internal contact pressure. This helps ensure the breaker is closing with proper force.
*Note on UVL Type
The UVL Type can be inspected in the same manner as the UVM Type.
Please refer to the UVM procedure for inspection guidance.
