Technical Data

For applications from 72.5 kV up to 800 kV

In contrast to dead tank circuit breakers, the interrupter unit in live tank breakers is not grounded during operation; it is exposed to high-voltage potential and therefore these circuit breakers are called live tanks.
The 3AP circuit breaker family is available for rated voltages from 72.5 kV up to 800 kV. 3AP1 circuit breakers up to 300 kV are equipped with one interrupter unit per pole and 3AP2 circuit breakers up to 550 kV include two interrupter units. For applications from 362 kV to 550 kV, the circuit breakers can be equipped with optional closing resistors (3AP3). The 3AP4 includes 4 interrupter units per pole and can also be delivered with closing resistors on request (3AP5).
Moreover, our high-voltage live tank circuit breakers are available for three-pole operation with a common base (FG), for single pole operation also with a common base (FE) or for one pole operation with separate bases (FI). In accordance with our modular design, all Siemens 3AP live tank beakers are provided with our stored-energy spring drive mechanism and our self-compression interrupter units.
