- Factory Testing: At Zhejiang Mingtuo Electric Technology Co., Ltd., we uphold a rigorous standard of excellence. Each Customized MCCB Molded Case Circuit Breaker, ranging from Model Mtezc-100 to Mtezc-630, undergoes a comprehensive suite of factory tests ensuring unparalleled quality and performance.
Mechanical Operation Testing: This essential evaluation certifies that every circuit breaker operates flawlessly, adapting to a spectrum of conditions with grace.
Content: Through repeated operations, we confirm the opening, and closing, ensuring every mechanism performs with exceptional flexibility and steadfast reliability.
Insulation Resistance Test: A cornerstone test that validates the electrical integrity and safety of our circuit breakers, empowering them with robust performance.
Content: Utilizing a high-precision insulation resistance tester, we meticulously measure the insulation resistance between each pole and its casing, ensuring unyielding insulation.
Voltage Withstand Test: This rigorous assessment safeguards the circuit breaker's endurance under high voltage challenges.
Content: We subject the breaker to high voltage, typically twice its rated capacity plus an additional 1000V, for a full minute, to ensure it withstands potential breakdowns, thereby fortifying its resilience and reliability.
Temperature Rise Test: A pivotal evaluation to ensure the thermal efficiency of our circuit breakers under operational conditions.
Content: Operating at rated current, we precisely measure the temperature rise at connection points and contacts, ensuring they adhere to safe limits.
- On-Site Testing: Our dedication to superior quality extends to meticulous testing at the installation site, providing assurance and peace of mind.
Power-On Test: This vital verification ensures the circuit breaker's readiness post-installation.
Content: We confirm the circuit breaker can open and close fluidly and effectively upon power-up, ensuring uninterrupted functionality.
Protection Function Test: A comprehensive array of tests designed to safeguard your systems with precision and care.
Overload Protection: By ingeniously simulating overload scenarios, we meticulously ensure the circuit breaker trips within the designated time frame, thereby securing your infrastructure. Short Circuit Protection: We emulate a
short circuit situation, guaranteeing the circuit breaker engages instantly, providing an unwavering shield against electrical hazards.
We employ premium, high-quality shockproof materials to ensure unparalleled protection for your valuable circuit breakers.
Material: Foam and bubble film, etc.
Placement: Thoughtfully and strategically placed evenly around the circuit breaker, encompassing both the top and bottom for full coverage.
