Abstract: A contact-finger-element includes a first contact-portion and a second-contact-portion which are suitable for engaging with a first conducting terminal and with a second conducting-terminal respectively; the first-contact-portion and the second-contact-portion have respective cross-sections including concave “V”-shaped profiles, each concave “V”-shaped profile having two straight portions mutually tilted by a respective included angle which is adapted so as to enable the first contact-portion and the second-contact-portion to tangentially contact with a curved surface of the first conducting terminal and of the second conducting terminal respectively at intermediate zones of the respective straight portions. There is also disclosed a tulip-contact assembly comprising a plurality of such contact-finger-elements.

Abstract: A retrofit assembly and method of retrofitting a circuit breaker in a switchgear are described. The retrofit assembly can includes one or more adjustable elements for fitting a circuit breaker into a switchgear panel of the switchgear. The adjustable elements can include a plurality of adjustable modular female tulip contacts to receive a corresponding plurality of male contacts in a panel of the switchgear, each female tulip contact being flexible for a plurality of diameters, a plurality of modular phase adjustment contact arms to provide phase alignment between the poles of the circuit breaker, and/or an adjustable truck for placing the circuit breaker in contact with a rack for the circuit breaker in the switchgear.
