Description：

VD4 evo circuit breakers are used in power distribution systems for controlling and protecting cables, transformer and distribution substations, motors, transformers and capacitor banks. VD4 evo includes a range of sensors for a seamless transition from traditional to digitally connected medium voltage circuit breakers. The integrated sensors enable advanced monitoring and diagnostic features for real-time monitoring of thermal, mechanical, and electrical parameters, allowing remote asset management and thus reducing maintenance cost and contributing to reduced downtime.
VD4 evo is also available in standard configurations without sensors. The flexibility of the design enables future digital upgrades, including sensors, if required.

Features：

• Full monitoring and diagnostics (M&D) flexibility.
• Mechanical chain and accessories anomalies detection.
• Loose connections detection and circuit breaker contacts monitoring.
• Advanced thermal checks & electrical life.
• The most compact medium voltage circuit breaker selection for your application.
• Third-party verified Environmental Product Declaration (EPD) for transparency of the environmental impact of the circuit breaker.
• QR code for fast retrieval of online documentation.
• Intuitive dashboard based on the Web browser-based HMI.

 Technical Characteristics:

Scope：

• Withdrawable and fixed medium voltage circuit breakers for primary distribution.
• The digital evolution of the IEC indoor vacuum circuit breaker VD4.
• VD4 evo p150 17.5 kV, up to 1250 A, 40 kA withdrawable (for UniGear ZS1 650 mm) and fixed.
