Installation Guidelines

Proper installation of sealing boots is critical to ensure optimal performance and protection. Follow these steps for effective installation:

1. Preparation:
   • Clean the circuit breaker surface to remove any dirt, grease, or debris.
   • Inspect the sealing boot for any damage before installation.
2. Positioning:
   • Align the sealing boot with the circuit breaker’s contours.
   • Ensure that the boot’s edges sit flush against the mounting surface.
3. Attachment:
   • Secure the boot using the provided SEELSKREWS® or other fasteners as specified.
   • Avoid over-tightening to prevent material deformation.
4. Testing:
   • Verify the integrity of the seal by performing a visual inspection.
   • Test the circuit breaker’s functionality to ensure unobstructed operation.
