An adjustment mechanism for a circuit breaker and the corresponding circuit breaker. The adjustment mechanism includes a pin adapted to move with respect to a base part of the circuit breaker along a predefined path; a first linkage coupled to the base part and adapted to drive a first terminal of the circuit breaker to move towards or away from the base part; and a second linkage coupled to a second terminal of the circuit breaker and adapted to be actuated by the pin to drive the second terminal to move towards or away from the base part. The groove has a first segment; and the second linkage is actuated by the pin and the first linkage is not actuated by the pin when the pin moves within the first segment in a first direction along the predefined path.

Adjustment mechanism for circuit breaker and corresponding circuit breaker

The present disclosure relates to a withdrawable base module for a switch. The withdrawable base module comprises a base coupled to a busbar for electrically connected to the switch; a conversion assembly coupled to the base and comprising a drive mechanism, a first female contact and a carrying mechanism adapted to carry the switch; and an auxiliary assembly being slidable relative to the conversion assembly and comprising a first male contact electrically connected to the switch; wherein the drive mechanism is operable to drive the auxiliary assembly to cause the first male contact to move towards and contact the first female contact. The withdrawable base module according to embodiments of the present disclosure can provide a test circuit for the switch, and can achieve the rocking-in or rocking-out of the switch without additional human intervention after completion of the test.
