Introduction / General
The product name VD4 does not change
VD4 as a brand-name for a high quality VCB is well-accepted
The actual VD4 name is now defined to “classic VD4”
Availability of “new VD4”
Production started in February 2003
Market introduction almost completed according to marketing plan

4. Introduction / General
Classic
and
New VD4
Introduction / General
An innovative concept for the maintenance
new VD4 has an actuator with a plug-in snapping-unit
just replacing the snapping-unit the c.breaker is basically a new c.breaker
new VD4 is the first MV circuit-breaker offering this feature
removal and mounting of the snapping-unit requires only 20 min.
the replacement operation is more reliable then any maintenance
operating life of the snapping unit up to 31.5 kA 17.5 kV (25 kA 24 kV) :
today: 10,000 operations already certified
today: 20,000 operations satisfactory carried-out
within 4Q 2003: 30,000 operations

16. Maintenance Classic and New VD4 Maintenance Classic New Remark
typical life-expectancy
30,000 cycles 1)
operating life of vacuum interrupters
up to 30,000 operations
depending on the vacuum interrupter type
operating life of actuator
up to 30,000 operations with maintenance
up to 30,000 operations with maintenance 2)
New VD4 is M2 class
interval of inspection
4 years or after 5,000 operating cycles
maintenance of actuator and transmission system
after 10,000 or 20,000 operations replacement 3) of single actuator components 4)
after 10,000 operations replacement 3) of the actuator unit 5)
replacement of the actuator unit is easier and faster respect to the replacement of single components
1) cycles under normal operating conditions, depending on breaker type, given regularly and conscientiously performed maintenance
replacement may be carried out only by ABB personnel or trained and qualified customer personnel
M2 class means 10,000 operations without maintenance; the activity is on going for 30,000 operations without maintenance; 30,000 operations without maintenance will be available within 4Q 2003
replacement after 10,000 operations (depending on circuit breaker type) : blocking lever, half shaft, crank; replacement after 20,000 operations (depending on circuit breaker type) : latch, complete supporting crank, spring, shaft, cam disk, return rotation blocking
replacement after 10,000 operations: actuator unit (snapping unit only; see next slide; snapping unit for 30,000 operations without maintenance will be available within 4Q 2003) replacement after 15,000 operations: shock absorber (the damper “shock absorber” for 30,000 operations will be available within 4Q 2003)

shunt releases are fundamentally wired with rectifiers (function as free-wheeling diodes if DC-supply) in order to obtain anti-pumping function; shunt releases are not mandatory with „new VD4“ in order to have anti-pumping function
mandatory for UniGear type ZS1, UniSafe, PowerBox; inclusive mechanical interlock (striker pin) if rated current is different from the panel
prevents the CB being racked into the panel with plug not inserted in the socket or no aux. Voltage; not available for motorized truck version
