Ensuring Quality: Our Inspection Workshop

In the electrical manufacturing industry, safety and reliability are paramount. At our factory, we take these concerns seriously, which is why every molded case circuit breaker (MCCB) undergoes rigorous testing in our dedicated final inspection workshop to ensure top-tier quality and performance.

Comprehensive Testing: Instantaneous and Time-Delay Tests

Before shipment, each MCCB is subjected to both instantaneous and time-delay tests. These tests are designed to verify the breaker’s response to different fault currents, ensuring that the device will operate correctly in the event of overloads or short circuits. By simulating real-world electrical conditions, we guarantee that our products will deliver the protection needed in critical situations.

Mechanical Performance Sampling: A Further Layer of Quality Control

In addition to electrical performance testing, we conduct mechanical performance tests on a random sampling basis. For every 10 breakers produced, 1 is selected for mechanical testing, where we assess durability, operational smoothness, and overall mechanical integrity. This sampling process allows us to ensure that our products maintain consistent performance, even under prolonged usage.

Continuous Improvement and Customization

Our testing protocols adhere to the highest industry standards, but we also offer tailored testing solutions based on specific customer requirements. With a skilled team of engineers and a commitment to continuous improvement, we strive to refine every step of our production and inspection processes.
