3RT1035-1BB40

Siemens provides the 3RT1035-1BB40 power contactor within the SIRIUS range, characterized by its capability to manage significant electrical loads. Operating with an insulation voltage reaching 690 V, the device is well-suited for high-voltage installations. The contactor supports a thermal short-time current of 400 A, providing robustness under transient electrical conditions. With three poles dedicated to the main circuit, this model ensures effective switching functionality.

The device is rated for a pollution degree of 3 while maintaining an impressive surge voltage resistance of up to 6 kV. Power consumption is kept low, with an active loss of only 2.6 W. Operating on a 24 V DC supply voltage, the magnet coil requires a closing power of 13.3 W, allowing for efficient actuation.

Designed to cater to various installation scenarios, the contactor is compatible with both screw and snap-on mounting methods. This flexibility simplifies installation in diverse applications. The dimensions of the unit are as follows: 112 mm in height, 55 mm in width, and 130 mm in depth, making it compact for its capabilities. Additionally, the maximum installation altitude is 2000 m, allowing for adaptability in different operational environments.
