  Precaution  

1.the plug of the charged plug controller is forbidden, otherwise the electric shock or the product will be damaged.

2.non professional personnel are prohibited from operation or maintenance, otherwise the danger of electric shock or damage to the product will be caused.

3.load capacity shall not exceed the rated capacity of the switch, otherwise the switch will be removed or burned.

4.The zero line (N)should not be connected to the phase line. The input of two circuit breakers must be the same. When the tree-level circuit breaker is used, connect the common line power (NN)and backup neutral line (RN)1 foot(N), otherwise it will lead to switch damage, grounding should be reliable, to ensure safety.

5.Do not install directly in outdoor work, otherwise it will shorten the service life or cause adverse reactions.

6.Do not install directly on the place with conductive dust or wire intruding, otherwise it will cause damage to product or cause mechanical failure.

  FAQ  

Question 1: What are the requirements for the ambient air temperature?
Answer: The ambient air temperature should be not higher than 40℃ and not lower than -5℃, and the 24 hours average temperature should not exceed +35℃.

Question 2: What are the restrictions on relative humidity and altitude according to the given information?
Answer: The relative humidity should not exceed 50% at 40℃, and higher relative humidity is allowed at lower temperatures but with consideration of possible condensation caused by temperature variation. The altitude should not be higher than 2000m.

Question3: What are the important precautions and potential risks to avoid when dealing with this electrical equipment in terms of operation, installation and connection?

Answer: Firstly, never plug or unplug the charged plug controller to avoid electric shock and product damage. Secondly, only professional personnel should operate or maintain it as non-professionals may face electric shock or damage the product. Thirdly, ensure the load capacity does not exceed the switch's rated capacity to prevent the switch from being removed or burned. Fourthly, correctly connect the lines: the zero line should not be connected to the phase line, the input of two circuit breakers must be the same, and when using a three-level circuit breaker, connect the common line power and backup neutral line properly to avoid switch damage, and make sure the grounding is reliable for safety. Fifthly, do not install it directly outdoors as it may shorten its service life or cause adverse reactions. Finally, do not install it in places with conductive dust or wire intrusion to prevent product damage or mechanical failure.

Question 4:What are MCB-Type CB-Level ATS and MCCB-Type CB-Level ATS?

Answer:

• MCB-Type CB-Level ATS: Uses Miniature Circuit Breakers (MCB) as switching components, suitable for low-current distribution systems (typically ≤125A).

• MCCB-Type CB-Level ATS: Uses Molded Case Circuit Breakers (MCCB) as switching components, suitable for medium-to-high current distribution systems (typically 100A~1600A).

Question 5: What Are the Key Differences?

Answer:

• Current Rating: MCB-type is for ≤125A, while MCCB-type supports up to 1600A.

• Breaking Capacity: MCCB-type has a higher breaking capacity (typically 10kA~100kA), while MCB-type is lower (usually 6kA~15kA).

• Size & Installation: MCB-type is compact, ideal for space-constrained areas; MCCB-type is larger and requires more installation space.

Question 6: How to Choose Between Them?

Answer:

• Choose MCB-Type: For low-current applications (e.g., lighting, sockets), limited budgets, or tight spaces.

• Choose MCCB-Type: For medium-to-high current loads (e.g., motors, transformers), high short-circuit currents, or where higher reliability is needed.
