Description
Switchgear for traction – AC vacuum circuit breaker
The CVB Series vacuum circuit breaker is the main electrical switch and protection device of AC locomotives and electric multiple units.
Mode of operation: The energy required to switch on the CVB is stored by a spring. As soon as the switch-on signal is applied, the main spring release latch is unlocked and the switching operation is triggered. After that the spring gets recharged in less than 10 s. The signal “Hold” will keep the CVB in its switched-on position. The vacuum circuit breaker is switched off when the signal “Hold” is cancelled or the control voltage supply is lost – the spring remains charged and ready for the next switching operation.
Features
- Long-lasting vacuum tube. Minimum wear and long, trouble-free service life
- Spring actuator: Function guaranteed even when battery is low
- Almost maintenance-free: 200,000 operating cycles with no need to
- adjust the main contacts, no maintenance of the pneumatic
- Operation without second source of energy, e.g. pneumatic
- Fail-Safe: Safe switching off in case of failure

Description
C152 to C154 Series cam contactors are rugged switchgear for switching AC and DC voltages that has stood the test of time. This most variable contactor series is designed for carrying out the various switching tasks as required in industrial and railway applications.
Main contacts: Available are 2, 3 and 4 pole contactor versions fitted with S306 Series cam switch elements. The double-break main contacts can be configured as SPST NC or NO and as a combination of both. To extinguish the arc when switching higher loads, there is the option of an arc chamber.
Features:
-Rugged design
-Various combination of switching elements (4 main / 4 auxiliary max.)
-Easy to replace switching elements
-Double-break contacts
-Extended coil tolerance
-Optional electronic economy circuit
