A charging assembly is provided for an electrical switching apparatus, such as a circuit breaker. The charging assembly includes a compression arm and a charging cam. The compression arm includes a pivot and first and second legs extending outwardly from the pivot, preferably in a generally L-shape. An engagement portion disposed at or about a second end of the first leg cooperates with an outer cam surface of the charging cam. A shaped contact surface disposed at or about a second end of the second leg includes a first edge for engaging and moving an impact member of the circuit breaker closing assembly to charge a biasing element of the closing assembly, and a second edge. The second edge is disposed at an angle with respect to the first edge, and is structured to engage the impact member when the biasing element is disposed in the charged position.
