Specification & Description
The Siemens 3RB2016-1SB0 is a robust and reliable overload relay designed to offer effective motor protection. Engineered for precision, this component is an integral part of the SIRIUS product family, known for its high-quality industrial control gear. With a trip class of 10, it ensures quick response to prevent motor damage due to overload conditions.
This solid-state overload relay is suitable for a three-phase main current circuit and features a current adjustment range of 3 to 12 A, making it versatile for various applications. The flange mount design allows for direct mounting, facilitating easy integration into existing systems. The device boasts a compact footprint with dimensions of 45 x 73 x 64 mm, ensuring it does not require excessive space within control cabinets.
The 3RB2016-1SB0 is equipped with screw-type terminals for both the main and auxiliary circuits, supporting solid and finely stranded wires, which simplifies the installation process. It is designed to operate effectively within a wide temperature range, making it suitable for challenging industrial environments.
With an insulation voltage rated at 690 V and an impulse voltage resistance of 6 kV, the relay is built to withstand significant electrical stress, ensuring long-term reliability and safety. The IP20 protection class indicates that the device is protected against solid objects larger than 12.5 mm, although it should be installed in a manner that minimises exposure to dust and moisture.
This overload relay is an essential component for industrial applications where motor protection is critical, such as in manufacturing, processing, and automation systems. Its solid-state design ensures minimal power loss and a high degree of accuracy in operation, contributing to the efficiency and longevity of the motors it protects.
