Circuit-breaker motion and contact-timing test tools

Applicable purchasers

Switches, contactors, transformers, connectors and electrical equipment companies

Test and assembly objects

Circuit breakers, excitation and position/contact references

Development and delivery

Synchronize action time, displacement and contact status, output working conditions and event records

Project input

Off-the-shelf electrical instrumentation, approval processes, electrical scope, tooling and wiring

Acceptance method

Compare the action displacement/time and contact reference to check the excitation, rebound, event sequence and repeatability; the test loop and approved working conditions are individually confirmed.

Implementation steps

Object and interface verification → Reference link and solution confirmation → Single module prototype → Instrument and equipment joint debugging → Independent reference re-inspection → Source code, configuration and record delivery.

Equipment condition and scope confirmation

The scope may include control boards, firmware, instrument drivers, host software, process configuration and test records. Mechanical fixtures, pressure-bearing structures, fluid circuits, power circuits and optical or acoustic references are provided or separately designed by the responsible parties. Measurement specifications are established through validation with the target equipment and independent references.

Source code, design documents, instrument licensing, procurement, on-site support and ongoing maintenance scope are listed in the project documents.
