The breakers are used to conduct current under normal operation mode and to
protect circuits against overloads and short circuit as well as to perform
routine switchings of electric circuits including induction motors. We
manufacture three types of the breakers: VA21-29 — with average breaking
capacity VA21-29В — with increased breaking capacity VA21-29Т — for city
transport (single-pole with three-pole breaker dimensions). According to the
type of mounting and the way the external conductor is connected to the main
circuit we produce: — for mounting on the panel with the front
connection; — for mounting on the panel with the rear connection.
