© ABB Power Technology Products Introduction / General Classic and New VD4 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 One CB factory: The advantage of EoS in VCBs DECMS:Excellence in vacuum, casting and embedding technology ITNIE:Excellence in AT & Logistics and production engineering

© ABB Power Technology Products Introduction / General Classic and New VD4 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
