DESCRIBE

ABB HDZ‑70‑30x is a spring‑charge motor / storage motor assembly designed for use in medium‑voltage vacuum circuit breakers to charge the operating springs that power breaker opening and closing actions. It is part of the breaker’s operating mechanism, providing reliable and repeatable energy storage for high‑speed switching operations in protective devices. The unit is typically installed on circuit breaker mechanisms (such as VD4 type breakers or similar designs) and energized to rotate and store energy in internal springs, readying the breaker for rapid actuation.
