- Factory Testing: Each and every circuit breaker unit is subjected to an exhaustive and meticulous factory testing procedure, ensuring our steadfast promise of unparalleled quality and superior performance.
Mechanical Operation Testing: This vital evaluation certifies that our circuit breakers function impeccably across a spectrum of conditions, delivering seamless and dependable performance.
Content: We conduct repeated operations of the circuit breaker to thoroughly confirm the opening, and closing, guaranteeing each action is executed with extraordinary agility and steadfast reliability.
Insulation Resistance Test: Our rigorous insulation resistance test is crucial in validating the robust electrical integrity and safety of our circuit breakers.
Content: Utilize a high-precision insulation resistance tester to intricately measure the insulation resistance between each pole and from the pole to its casing, ensuring uncompromising insulation strength.
Voltage Withstand Test: This test verifies the circuit breaker's remarkable endurance under high voltage scenarios.
Content: We apply a high voltage, typically twice the rated voltage plus an additional 1000V, for a duration of 1 minute, to inspect for any potential breakdown, thus fortifying our product's exceptional resilience.
Temperature Rise Test: An essential assessment to confirm optimal thermal performance.
Content: Operate the circuit breaker at its rated current and precisely measure the temperature rise at the wiring terminals and contacts, ensuring they remain safely within operational thresholds.
- On-Site Testing: Our promise of excellence persists through rigorous testing at the installation site.
Power-On Test: This pivotal test confirms the operational readiness of the circuit breaker post-installation.
Content: We ensure the circuit breaker can open and close effortlessly and with precision after being powered on, ensuring flawless functionality.
Protection Function Test: A comprehensive array of tests devised to protect your systems.
Overload Protection: Artfully simulate overload conditions to painstakingly confirm the circuit breaker trips within the defined time frame, safeguarding your infrastructure. Short Circuit Protection: Simulate a
short circuit condition, ensuring the circuit breaker trips immediately, offering unwavering protection against electrical faults.
We meticulously utilize premium shockproof materials to guarantee unparalleled protection.
Material: Foam and bubble film, etc.
Placement: Thoughtfully and uniformly positioned around the circuit breaker, ensuring coverage both on the top and bottom.
