1. A crossbar assembly comprising:
a crossbar extending in one direction, and configured to rotate in response to an overcurrent flowing in a circuit associated with a circuit breaker in which the crossbar assembly is disposed to perform a trip operation of the circuit breaker; and
an instant bar extending in the one direction and rotatably coupled to the crossbar, and configured to rotate independently of rotation of the crossbar in response to a fault current flowing in the circuit to perform the trip operation,
wherein the crossbar comprises:
an insertion space portion formed through an inside of the crossbar in the one direction, accommodating the instant bar, and having one side facing the instant bar open;
a first body portion extending in the one direction and surrounding a part of the insertion space portion; and
a second body portion extending in the one direction and surrounding another part of the insertion space portion.
