The Hathaway CBT-400 is a portable, microprocessor-based Circuit Breaker Test System designed specifically for the timing, analysis, and testing of medium and high-voltage circuit breakers. Built to replace its predecessor, the CBT4, it is engineered for both factory quality assurance and rugged field environments, offering immunity to the high levels of electrical interference typically found in high-voltage substations.

Here are the key features and capabilities of the product:

• Comprehensive Measurement: Accurately records contact opening and closing timings, open and close coil currents, and dynamic contact resistance.

   

• Motion Analysis: Captures and monitors mechanism travel and velocity to help operators assess the mechanical health and alignment of the breaker.

   

• Automated Testing Sequences: Capable of storing up to 16 different test configurations. It allows multiple tests to be executed in sequence (and cycled up to 99 times) for rigorous factory testing.

   

• Intelligent Results Analysis: Automatically compares actual test results with pre-programmed, expected operational limits, highlighting any variances directly on the display or printout.

   

• Standalone Operation: Housed in a durable, shock-resistant case with an integral keypad and LCD display, allowing full operation and menu-driven testing without the immediate need for a computer on-site.

   

• Data Management: Stores all test records and configurations internally. Data can be later downloaded to a PC via a direct link or modem for archiving, detailed analysis, and custom report generation using Windows-compatible database software.
