A nozzle (100) for a circuit breaker (1000), the circuit breaker (1000) having at least two contact elements (210, 220) and a gas reservoir (310) is provided. The nozzle (100) is manufactured by 3D printing as a single piece and is configured to surround the at least two contact elements (210, 220). The nozzle includes an arcing zone (330) formed along a central axis (CA) of the nozzle (100), and a gas channel (320) formed within the nozzle (100), the gas channel (320) configured to fluidly connect the gas reservoir (310) and the arcing zone (330). At least one of the contact elements (210, 220) is configured to be movable.
