with Auto-Puffer for outdoor installation
LTB D is operated by a motor-charged spring operating mechanism type BLK or FSA, or by the digital servomotor-system, Motor Drive. The energy required for interrupting short-circuit current is partly taken from the arc itself, thereby reducing the energy required from the operating mechanism to less than 50 percent compared to a conventional SF
6 puffer-type circuit breaker. The low energy requirements result in reduced stresses, which in turn lead to increased reliability.
