LS-B60 Circuit Breaker Tripping Characteristics Comprehensive Test System

The LS-B60 Circuit Breaker Tripping Characteristics Test System is a precision instrument engineered for comprehensive performance evaluation of circuit breakers in accordance with international standards. This system implements PLC-based intelligent control with a human-machine interface (HMI) for operational efficiency and repeatability. The integrated design combines test chamber and control unit with dedicated test stations for delayed tripping and instantaneous tripping positions. Utilizing a low-voltage, high-current output methodology with an integrated high-current isolation transformer, the system delivers precise current regulation for standardized testing protocols.

This equipment enables execution of time-delay tripping tests, instantaneous tripping tests, and temperature rise tests per IEC 60947-2, IEC 60898-1, and GB 14048.2 requirements. Through automated parameter adjustment and environmental temperature control, the system ensures stable testing conditions for accurate performance characterization across various circuit breaker specifications. The scientific wiring configuration accommodates multiple device form factors while maintaining test integrity.
