ABSTRACT:
An electrical contact assembly used for a circuit breaker comprises a pair of relatively movable U-shaped contact and bar conductor, and a holder provided with a recess for receiving the U-shaped contact. The U-shaped contact has contacting portions formed by slightly bending both sides thereof inwardly to form a narrow opening for clamping the bar conductor. The electrical contact assembly further comprises conductive members which are disposed on both sides of the U-shaped contact and electrically connected thereto, so that currents passing through the conductive members symmetrically flow in a direction opposite to a flow direction of currents passing through the both sides of the U-shaped contact when the U-shaped contact and the bar conductor are engaged.
