Packaging, Transportation and Storage Precautions

(1) Circuit breaker should be in the state of opening and energy storage spring in a state without energy storage when packing. It should be in the state of opening and energy storage spring in a state without energy storage when packing. And it should be fixed on the bottom of the wooden case, should have waterproof measures and complete package labels.
(2) Circuit breakers can't invert and avoid strong vibration, rain, surface damage, and components lost when transportation.
(3) When loading the circuit breaker, we suggest the following tools: crane, forklift and driving. When lifting the circuit breaker, we should not hook on the body or pole of the circuit breaker, but on the lifting hole which has the lifting mark.
(4) When circuit breaker has a long-term storage, it should be in a state of opening and energy storage spring in a state without energy storage and placed in dry ventilated indoor preventing from moisture, vibration control and harmful gas erosion, and regularly checked whether environment meets the requirements.
(5)When first use products after long-term storage, it need to have a power frequency withstand voltage insulation testing.
