Abstract (en)
A tulip contact (10) for a circuit breaker configured for receiving a corresponding plug (11), a circuit breaker comprising a tulip contact (10) described herein, and a method for producing a tulip contact (10) for a circuit breaker are described. The tulip contact (10) comprises a tubular base portion (25) from which a plurality of contact fingers (20) extends substantially in a direction of a longitudinal axis (26) of the tulip contact (10). A free-leading end portion (23) of the contact fingers (20) is configured for establishing an arc with the corresponding plug (11). Further, the tulip contact (10) comprises a high-strength portion (21) having a Young's modulus of 90 GPa to 140 GPa and a yield stress of 500 MPa to 1350 MPa.
