Installation Instructions
· The MTN and MTH800A to 6300A (excluding 4000A) range offer identical connection terminals,;
ensuring you don't need to allocate extra space for front connections since the terminals maintain the circuit breaker's compact depth;
· For seamless integration with either horizontal or vertical busbars, just rotate the connection terminal a swift 90 degrees for optimal alignment.Product testing
Mechanical operation test:
Ensure the seamless and smooth mechanical operation of the circuit breaker is flexible and reliable, ensuring consistent performance.
Conduct comprehensive operation tests on functionalities such as closing, opening, and energy storage, to guarantee impeccable operation.
Electrical performance testing:
Insulation resistance test: Deploy a megohmmeter to precisely measure the insulation resistance of both main and auxiliary circuits, ensuring they surpass the standard requirements (usually ≥ 1M Ω).
Power frequency withstand voltage test: Subject the main and auxiliary circuits to a rated power frequency voltage (such as 2500V/1min) to meticulously validate their insulation performance.
Contact resistance test: Accurately measure the contact resistance of the main contact, ensuring it remains comfortably below the specified value, typically at a micro ohm level, for optimum functionality.
Protection function test:
Evaluate the precise action values and timing of protection functions such as overload, short circuit, and ground fault, ensuring their reliability.
Verify the meticulous settings andfunctionality of the sophisticated intelligent release device for optimal safety and performance.
Packaging & Shipping
Outer Packaging:
Robust wooden crates are meticulously selected to ensure optimal mechanical strength.
Ideal for large circuit breakers or international shipments
Inner Packaging:
The circuit breaker is lovingly encased with protective layers like foam padding, bubble wrap or pearl cotton to safeguard against any jolts or impacts.
For larger breakers, a multi-tiered box design is employed, with additional items (such as instruction manuals, tools, spare components) elegantly arranged on the top layer
