Specify the full TB model, pitch, retention variant and pole count. XXP identifies the selected pole count in the model drawings. Allow access to the spring cage actuators and wire entry, and include the complete lever or flange envelope in the installation layout. Check the exact model attachment for its contact arrangement and mounting detail.
