Abstract
A contact arm assembly includes a contact arm defining a central axis and having a first end configured for electrical connection with a pole of a circuit breaker and a second end having a distal end defining a shoulder and an engagement that protrudes from the contact arm proximal to the shoulder. A plurality of contact fingers are mounted circumferentially on the second end of the contact arm and configured to electrically engage a primary circuit contact. Each contact finger has a body with a depression that receives the engagement for electrical contact.
