- Factory Testing: At Zhejiang Mingtuo Electric Technology Co., Ltd., each Customized MCCB Molded Case Circuit Breaker undergoes a rigorous series of factory tests, ensuring unmatched quality and performance at every level.
Mechanical Operation Testing: This essential evaluation ensures our circuit breakers perform flawlessly across diverse operational scenarios, providing seamless functionality.
Content: We conduct multiple operation cycles on our circuit breakers, meticulously verifying the opening, and closing, thereby assuring each action is executed with remarkable adaptability and steadfast reliability. ensuring that each action is executed with exceptional flexibility and unwavering reliability.
Insulation Resistance Test: A critical measure that substantiates the electrical soundness and security of our circuit breakers.
Content: We employ a precision-engineered insulation resistance tester to meticulously evaluate the insulation resistance between poles and between each pole and its casing, confirming enduring insulation capability.
Voltage Withstand Test: An essential evaluation to ensure the circuit breaker's durability under high voltage stress.
Content: We subject the circuit breaker to a high voltage, typically twice its rated voltage plus an additional 1000V, maintaining this for a full minute, to detect any signs of potential breakdown, thus fortifying our commitment to resilience and reliability.
Temperature Rise Test: A vital assessment to guarantee supreme thermal efficiency.
Content: We operate the circuit breaker steadily at its rated current, measuring the temperature elevation at the terminals and contacts, ensuring they remain comfortably within safe operational parameters.
- On-Site Testing: Our pursuit of excellence extends to comprehensive assessments at the installation site.
Power-On Test: This pivotal test confirms the circuit breaker's readiness and effectiveness post-installation.
Content: We meticulously confirm the circuit breaker's ability to open and close smoothly and efficiently once powered, safeguarding against any functional impediments.
Protection Function Test: A strategic suite of evaluations to ensure system safety.
Overload Protection: By simulating overload conditions, we diligently verify that the circuit breaker trips within the designated timeframe, thereby protecting your valuable infrastructure. Short Circuit Protection: Through simulated
short circuit conditions, we ensure the circuit breaker trips instantly, providing an unyielding shield against electrical discrepancies.
We proudly utilize premium shockproof materials, ensuring unparalleled protection for your product.
Material: Innovative foam and bubble film, and more.
Placement: Thoughtfully positioned around the circuit breaker, safeguarding both its top and bottom.
