MCB manual thermal trip calibration bench

The MCB Manual Short-Time Delay Test Bench is a specialized device designed to evaluate the short-time delay characteristics of miniature circuit breakers (MCBs). Operators can manually set test parameters and observe the breaker’s delayed trip behavior under controlled overload conditions. The system features clear digital displays, stable test channels, and a user-friendly interface for accurate time-delay measurement. Its durable structure and simple operation make it ideal for small-batch production, laboratory analysis, and quality inspection. This test bench ensures MCBs meet required short-time delay standards, providing reliable verification for safety and performance.
