ME3205 type universal circuit breakerDetailed product description：

ME3205 circuit breaker is suitable for rated working voltage from A.C to 380V, 660V, 50Hz; The distribution circuit with a rated working current of 630A-3900A is used for infrequent conversion and protection against overload, undervoltage, and short circuit of the line and electrical equipment. And it has graded selection protection. It can directly start the motor and protect the motor, generator, rectifier device, etc. from abnormal conditions such as overload, short circuit, and undervoltage.

1、 Characteristics of ME3205 Circuit Breaker:
ME3205 circuit breaker has a compact structure, small size, light weight, and strong series performance. Good interchangeability of components, complete protection system, high technical and economic indicators, and easy maintenance and use.
1. Type: Installation methods: fixed type and drawer type. 2. Polarity: Three poles, four poles.

2、 ME3205 Circuit Breaker Operation Method:
The operation mode of ME3205 circuit breaker includes manual direct operation on the right side; Direct manual operation on the front side; Front manual quick operation; Quick operation of electric motor; There are five ways to operate electric motors for energy storage. The operation of the electric motor with energy storage and release is divided into two processes: the first process is energy storage, which can be completed by simply operating the energy storage button. The second process is the closing operation. When the circuit breaker needs to be closed, simply turn on the closing operation button to complete it. The time from receiving the closure order to completing the closure operation is about 100ms.

3、 Environmental conditions for the use of ME3205 circuit breaker:
1. The ambient temperature should not be higher than+40 ℃ and not lower than -5 ℃ And the 24-hour average value shall not exceed+35 ℃.
2. The installation location should have an altitude of 2000m or below.
3. The atmospheric conditions are such that the relative humidity does not exceed 50% when the ambient air temperature is 40 ℃; At lower temperatures, there can be higher relative humidity, with an average minimum temperature of no more than+25 ℃ in the wettest month and an average maximum relative humidity of no more than 90%, taking into account temperature changes that may cause condensation on the surface of the product.
4. Pollution level: It should comply with pollution level three.
5. Installation conditions: The circuit breaker should be installed as a complete set according to the instructions or separately installed indoors, with a tilt angle of no more than 5 degrees from the vertical.
