The Siemens 3RB3036-1UB0 is a state-of-the-art solid-state overload relay designed for motor protection. This component is part of the SIRIUS product family and is engineered to provide reliable protection for three-phase motors. With a size S2 footprint, it is compatible with similarly sized contactors, making it a versatile choice for various industrial applications.
The overload relay offers a trip class of 10E and an adjustable response value current range of 12.5 to 50 A, ensuring precise protection for motors against excessive current draw that could lead to damage. It is designed for direct mounting onto contactors, facilitating a streamlined installation process.
Featuring an insulation voltage rated at 690 V and a surge voltage resistance of 6 kV, the 3RB3036-1UB0 is built to withstand challenging electrical environments. The device is also equipped with an integrated auxiliary switch with one normally closed (NC) contact for contactor disconnection and one normally open (NO) contact for tripped condition signalling, enhancing its functionality.
The overload relay is designed with user safety in mind, boasting a protection class of IP20 on the front and finger-safe terminals to prevent accidental contact. Its robust construction ensures shock resistance in compliance with IEC 60068-2-27 standards and vibration resistance for a wide range of industrial settings.
For ease of maintenance, the 3RB3036-1UB0 features a manual-automatic-reset function and a clear slide switch display for switching status. Its electronic design of the overload release ensures a swift recovery time after an overload trip, minimising downtime and maintaining operational efficiency.
This overload relay is not only a reliable component for motor protection but also a testament to Siemens' commitment to quality and innovation in industrial control technology.
