Siemens' 3RT1275-6AF36 vacuum contactor is engineered for high-performance electrical switching. This model supports a maximum operational current of 610 A, making it suitable for substantial industrial loads. The contactor also features impressive insulation properties, rated at 1000 V, which enhances its ability to handle significant electrical stresses. Additionally, it boasts surge voltage resistance capabilities up to 8 kV, ensuring durability and reliability in demanding environments.

Power loss associated with operation is measured at 63 W and is calculated using a quadratic formula that depends on the number of poles. In terms of construction, this device weighs 10.566 kg and encompasses three poles. The shock resistance rating is notably high at 8.5 g for a duration of 5 milliseconds, indicating resilience against mechanical shocks.

Electric control is facilitated with a closing magnetic coil power of 920 W, and for sustaining states at DC, it requires a holding power of 10 W. The opening delay for the contactor is set within the range of 60 to 100 milliseconds, allowing for regulated operations. Fastening is achieved through screws, providing stable installation in various settings. The electrical connections are made via screw-type terminals, ensuring secure and reliable connectivity.
