SRMC12 series AC contactorDetailed product description：

SRMC12 series AC contactors (hereinafter referred to as contactors) are mainly used in circuits with AC 50Hz or 60Hz, rated working voltage up to 1000V, and rated working current up to 630A for remote connection and disconnection of circuits. They can also be combined with appropriate thermal overload relays to form electromagnetic starters to protect circuits that may experience operational overload.  
The product complies with IEC60947-4-1 and GB14048.4 standards.

Normal working and installation conditions of SRMC12 series AC contactors

1. The ambient air temperature ranges from -5 ℃ to+40 ℃. The average value within 24 hours shall not exceed+35 ℃;
2. Altitude: not exceeding 2000m
3. Atmospheric conditions: At+40 ℃, the relative humidity of the air does not exceed 50%; 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% in that month, taking into account condensation that may occur on the product due to temperature changes;
4. Installation conditions: The inclination between the installation surface and the vertical surface shall not exceed 5 °;
5. Impact vibration: The product should be installed and used in a place without significant shaking, impact, and vibration.
