Abstract: A circuit breaker includes two sets of separable contacts in series per pole, primary contacts and secondary contacts, reducing overall let-through energy and peak pressures within the arcing chambers of the breaker during arc interruption. Opening both sets of contacts produces two arcs in series per pole, and the two series arcs increase the line to load resistance of the breaker relative to when only one set of contacts are opened. The increased line to load resistance causes the peak let-through current, Ipk, to decrease relative to what Ipk would be if only one set of contacts were to be opened. The circuit breaker also includes an internal primary vent that vents gases away from the primary contacts to another area within the circuit breaker housing, and a secondary exhaust vent that vents gases away from the secondary contacts to the exterior of the circuit breaker.
