- Factory Testing: Every circuit breaker unit undergoes comprehensive factory testing to uphold our commitment to quality and performance.
Mechanical Operation Testing: This critical assessment guarantees that our circuit breakers operate seamlessly under various conditions.
Content: We perform repeated operations of the circuit breaker to verify the opening, and closing, ensuring that each action is executed with exceptional flexibility and unwavering reliability.
Insulation Resistance Test: Our insulation resistance test is pivotal in affirming the electrical integrity and safety of our circuit breakers.
Content: Employ a high-precision insulation resistance tester to meticulously measure the insulation resistance between each pole and between the pole and its casing, ensuring robust insulation.
Voltage Withstand Test: This test ascertains the endurance of the circuit breaker under high voltage conditions.
Content: We apply a high voltage, typically twice the rated voltage plus an additional 1000V, for a duration of 1 minute, to check for any potential breakdown, reinforcing our product's resilience.
Temperature Rise Test: An indispensable evaluation to ensure optimal thermal performance.
Content: Operate the circuit breaker at its rated current and accurately measure the temperature rise at the wiring terminals and contacts, ensuring they remain within safe operational limits.
- On-Site Testing: Our commitment to excellence continues with thorough testing at the installation site.
Power-On Test: This crucial test verifies the operational readiness of the circuit breaker after installation.
Content: We ensure the circuit breaker can open and close smoothly and effectively after being powered on, ensuring no hitches in its functionality.
Protection Function Test: A series of tests designed to safeguard your systems.
Overload Protection: Ingeniously simulate overload conditions to meticulously verify that the circuit breaker trips within the specified time limit, protecting your infrastructure. Short Circuit Protection: Simulate a
short circuit condition, ensuring the circuit breaker trips instantly, providing an unfaltering defense against electrical faults.
We employ high-quality shockproof materials to ensure the utmost protection.
Material: Foam and bubble film, etc.
Placement: Strategically placed evenly around the circuit breaker, covering both top and bottom.
-External Packaging
Sturdy carton
