The VCBA 01 from Power Diagnostic Instrument Company is a next-generation, field-portable analyzer engineered for fast, accurate, and reliable testing of vacuum circuit breakers. Compact, lightweight, and easy to operate, it empowers field technicians to perform comprehensive diagnostics with confidence and efficiency.

Key Features & Functions

• High-Voltage DC Vacuum Integrity Testing: Verifies the condition of circuit breaker vacuum bottles by applying a precise
  DC test voltage to the arcing chamber.
• Automatic Leakage Current Monitoring: Continuously measures leakage current to ground during testing to ensure the
  vacuum integrity of the breaker contacts.
• Smart Pass/Fail Decision: The VCBA 01 automatically evaluates results against user-defined limits. If leakage current remains below the threshold, the test is logged as Pass; if exceeded, the instrument immediately stops the test and records a
  Fail result—protecting both the equipment and the operator.
