Auxiliary switch (S1) 3SV92
Two versions of the auxiliary switch can be supplied.
The standard version is fitted with 6 NO contacts and
6 NC contacts. The extended version is fitted with
12NO contacts and 12NC contracts.

Low-voltage plug connector (X0)
The control elements of the 3AH3 vacuum circuit-
breaker provided in the mechanism housing are wired
for external connection to the plug connector(X0). The
standard version is provided with a 64-pole plug
connector.
Shunt closing release (Y9) 3AY1510
The closing solenoid unlatches the charged closing
spring and thus closes the circuit-breaker electrically
It is available for both AC and DC operation. After
completion of a closing operation, the closing solenoid
is de-energized internally.
Power consumption approx. 140 W/VA
Shunt releases (shunt opening releases)
The shunt releases are used for automatic tripping of
circuit-breakers by means of appropriate protective
relays and for deliberate tripping by other electrical
means. They are designed for connection to external
voltage (DC or AC voltage). In special cases, for
deliberate tripping, they can also be connected to a
voltage transformer.
Shunt releases based on two different operating
principles are used.
Shunt release (Y1) 3AY1510
The 3AY1510 shunt release is used as standard in the
basic circuit-breaker version, with this design, the
electrically supplied tripping pulse is passed to the
"open" latching mechanism by means of a direct-action
solenoid armature and the circuit-breaker is thus
opened. It is available for both AC and DC operation.
After completion of an opening operation, the AY1510
shunt release is de-energized internally. In operation
with AC voltage, a rectifier module 3AX1525-1F is
installed in the circuit-breaker.
Power consumption approx. 140 W/VA

合闸线圈(Y9) 3AY1510
合闸线圈通电动作使合闸弹簧释放能量, 这就是电气合
闸. 交直流操作均可, 合闸完成后,合闸线圈失电.
功率消耗约 140 W/VA
分励脱扣器 (分闸线圈)
分励脱扣器是用于经由相应的保护继电器来实现断路器
自动脱扣的装置,还可用于其他的电气措施来实现某些特
定的脱扣动作.分励脱扣器由直流或交流电源供电, 在特
殊情况下, 它们也可接在电压互感器上
分励脱扣器有两种不同的脱扣原理.
分励脱扣器 (Y1) 3AY1510
3AY1510 分励脱扣器是断路器基本结构的标准脱扣器.
该脱扣器可以直接用线圈的铁芯"打开"锁扣机构, 于是断
路器分闸. 交直流操作均可, 分闸完成后,分励脱扣器失电.
交流操作时,断路器加装 3AX1525-1F 整流模块.
