-Factory Testing
Mechanical Operation Testing
Content: Engage the circuit breaker in multiple operational cycles to ensure the opening and closing are seamless, smooth, and reliable, ensuring optimal performance.
Insulation Resistance Test
Content: Utilize a highly precise insulation resistance tester to meticulously measure the insulation resistance between each pole of the circuit breaker and between the pole and its protective casing.
Voltage Withstand Test
Content: Apply a high voltage (commonly twice the rated voltage plus 1000V) for 1 minute and scrutinize the system for any potential breakdowns.
Temperature Rise Test
Content: Operate at the rated current and accurately measure the temperature increase of both wiring terminals and contacts to ensure they remain within safe operational limits.
-On Site Testing
Power-On Test
Content: Confirm that the circuit breaker can open and close smoothly and effectively once powered on, ensuring full functionality.
Protection Function Test
Overload Protection: Simulate an overload scenario and verify that the circuit breaker trips within the predetermined time frame for safety assurance.
Short Circuit Protection: Simulate a short circuit condition and ensure the circuit breaker trips instantaneously, safeguarding the system from potential damage.
Designed with exceptional care, our shockproof material ensures optimum protection.
Material: Our use of foam and bubble film creates a resilient barrier around the product,providing unparalleled defense against any impact.
Placement: Strategically placed around the circuit breaker, both at the top and bottom, to safeguard every angle.
