Siemens circuit breaker
Normal operating conditions and installation conditions The surrounding air temperature is ℃℃, and its average value within an hour does not exceed ℃
The altitude does not exceed
Atmospheric conditions When the relative temperature of the atmosphere does not exceed ℃ , relatively high relative humidity can be achieved at lower temperatures, the average minimum temperature of the wettest month does not exceed ℃, and the monthly average maximum relative humidity of that month does not exceed. And consider condensation on the product due to temperature changes
Pollution level
Installation category III
Installation conditions The inclination between the installation surface and the vertical plane does not exceed
Shock vibration products should be installed and used in places without significant shaking, shock and vibration.
Installation method In addition to being installed with screws, the contactor can also be installed with a standard rail. AC operation can be used or clamping rail installation is available. Note: DC operation can only use clamping rails, and there are special clamping rails for installation.
Two structural features
The contactor is a protective type, the action structure is a direct-acting type, and the contact is a double break point. It has the characteristics of small size, light weight, low power consumption, long life, safety and reliability
The contactor can be composed of a mechanical reversible interlocking magnetic starter, a star-delta decompression starter, and can also be combined with various derivative products such as an auxiliary contact group and an air delay head according to the user's choice.
