3RT2016-1BB42

The Siemens model 3RT2016-1BB42 contactor is a part of the SIRIUS series, known for its rugged and efficient design. This contactor is classified as size S00 and features three normally open main contacts, making it suitable for various control and switching applications. However, it is important to note that this model does not support a communication function module.

It can handle a rated insulation voltage of 690V and has a surge voltage resistance rating of up to 6 kV. These specifications ensure the contactor's ability to withstand high voltage transients, providing added reliability in electrical systems. The maximum permissible isolation voltage between the coil and the main contacts is rated at 400V, ensuring safe operation.

This model maintains an IP20 protection rating, indicating it is best suited for indoor environments with minimal exposure to dust and moisture. In terms of environmental tolerances, the contactor operates efficiently in temperatures ranging from -25 to 60 degrees Celsius.

The robust design results in a considerable mechanical service life, rated for about 30 million switching cycles, which translates to fewer replacements and reduced maintenance costs. Additionally, the unit's pollution degree rating is at Pollution Degree 3, further supporting its use in applications that may involve pollution or debris. Overall, the Siemens 3RT2016-1BB42 contactor provides a durable and effective solution for various industrial control applications.
