The Siemens 3RU2116-1DB0 is a meticulously engineered overload relay designed to offer reliable motor protection. This component is part of the SIRIUS range and is suitable for a size S00 contactor setup. It features a trip class of 10 and an adjustable current range of 2.2 to 3.2 A, ensuring precise protection for motors against excessive load or potential overload conditions. Constructed to maintain performance within a broad range of operating temperatures, from -40°C to +70°C, it is versatile for use in various industrial environments. The relay is also designed with a three-pole main current circuit, which can handle operating voltages up to 690V in AC-3 applications, making it a robust choice for numerous applications. The 3RU2116-1DB0 includes integrated auxiliary contacts, with one normally closed (NC) contact for contactor disconnection and one normally open (NO) contact to signal when the device has tripped. This feature allows for straightforward monitoring and diagnostics within your control system. With an insulation voltage rated at 690V and an altitude installation site capability of up to 2000 meters above sea level, this overload relay is crafted to meet the demands of a wide array of electrical setups. Its compact design and finger-safe terminals provide added convenience and safety during installation and maintenance. This overload relay is a testament to Siemens' commitment to quality, reliability, and precision in motor control and protection. It is an essential component for industrial applications where motor integrity is critical to operations.

What is the function of this overload relay?

The overload relay is designed to protect motors from overcurrent by tripping the circuit when current exceeds a preset level, ensuring the motor operates within safe parameters.

Can this overload relay be used in hazardous locations?

Yes, it has general product approval for use in hazardous locations, making it suitable for a variety of industrial environments.

What is the trip class of this overload relay?

It has a trip class of 10, which means it will trip within 10 seconds at 600% of its rated current, providing quick protection against overloads.

What are the ambient temperature limits for operating this relay?

The relay can operate within an ambient temperature range of -40°C to +70°C, ensuring reliable performance in a wide range of environmental conditions.

What is the significance of the adjustable pick-up value current?

The adjustable pick-up value current, ranging from 2.2 to 3.2 A, allows for precise setting of the current threshold at which the relay will trip, tailoring protection to the specific motor it is safeguarding.

What type of connections does this overload relay support?

It supports screw-type terminals for both the main current circuit and auxiliary and control current circuits, providing a secure and reliable connection.

Is there a specific size for the contactor that can be combined with this relay?

Yes, the overload relay is of size S00 and can be combined with a contactor of the same size, ensuring compatibility and ease of integration in motor control systems.

How many poles does the main current circuit of this relay have?

The main current circuit of the relay has 3 poles, which is typical for three-phase motor protection applications.

What is the insulation voltage rating of this overload relay?

The insulation voltage rating is 690 V with a degree of pollution 3, indicating its capability to withstand high-voltage environments without compromising safety or performance.

What is the operating power of this relay at different voltages?

At 400 V, the operating power is rated at 1.1 kW, at 500 V it's 1.5 kW, and at 690 V the relay can handle up to 2.2 kW, accommodating a range of power requirements for motor protection.
