ABB VD4 Series VCB

Description

ABB VD4 Series VCB: VD4 Medium voltage vacuum circuit-breakers 12…24 kV – 630…3150 A – 16…40 kA
The new VD4 is a synthesis of the renowned technology in designing and constructing vacuum interrupters embedded in resin poles and of excellence in design, engineering, and production of circuit-breakers. The VD4 medium voltage circuit breakers use vacuum interrupters embedded in resin poles. Embedding the interrupter in resin makes the circuit-breaker poles particularly sturdy
and protects the interrupter against shocks, accumulation of dust, and humidity. The vacuum interrupter houses the contacts and makes up the interrupting chamber.

Vacuum interruption technique

• Vacuum contacts protected against oxidation and contamination
• Vacuum interrupter embedded in the resin poles
• Interrupter protected against shocks, dust, and humidity
• Operation under different climatic conditions
• Limited switching energy
• Stored energy operating mechanism with anti-pumping device supplied as standard
• Simple customization with a complete range of accessories
• Fixed and withdrawable version
• Compact dimensions
• Sealed-for-life poles
• Sturdiness and reliability
• Limited maintenance
• Circuit-breaker racking in and racking out with the door closed
• Incorrect and hazardous operations are prevented thanks to special locks in the operating mechanism and the truck
• High environmental compatibility

ABB VD4 Series VCB Features:

• Highly reliable operating mechanisms thanks to a low number of components that are manufactured using production systems for large quantities
• Extremely limited and simple maintenance
• The accessories are common to the whole range and are identical for either a.c. or d.c. applications
• The electrical accessories can be installed or replaced easily and rapidly thanks to the cabling which is already prepared with its plug-socket connectors
• Mechanical anti-pumping device is supplied as standard
• Built-in closing spring charging lever
• Key lock with circuit breaker open
• Protective covering over the opening and closing pushbuttons to be operated using a special tool
• Padlock device on the operating pushbuttons
