Mounting an Open Fuse Auxiliary Switch with a Shunt Trip
An open fuse auxiliary switch can be installed on the A-
mechanism along with a shunt trip.
1. Follow the instructions for installing the shunt trip but
do not secure the clamp onto the half-moon shaft so
the white disk can be removed as shown in figure 23.
2. Bolt the open fuse auxiliary switch to the mounting
holes as shown in figure 24.
3. Rotate the white disk until it reaches its maximum
displacement and mark the hole adjacent to the white
roller on the open fuse auxiliary switch as shown in
figure 25.
