About this item

Model: 3TX4490-3R
A surge suppressor, also known as a surge protector or transient voltage suppressor, is an electrical device designed to protect electronic and electrical equipment from sudden voltage spikes and current surges that can occur in the electrical grid. These voltage surges, also called transient overvoltages, can be caused by a variety of factors, such as atmospheric discharges (lightning), maneuvers in the electrical grid, switching of heavy loads, among others. They pose a threat to sensitive devices such as computers, televisions, electronic appliances, and automation systems.
The main function of a surge suppressor is to detect these voltage peaks and divert the high-intensity transient current to the ground, preventing it from reaching connected devices. This helps protect sensitive equipment from damage caused by overvoltages, which can result in malfunction or permanent failure.
The SIEMENS 3TX4490 3R surge suppressor element is an electrical device used to protect electrical equipment against voltage surges. It consists of a varistor connected in series with a resistor.
The SIEMENS 3TX4490 3R surge suppressor element is designed for use in industrial applications where a high level of reliability and performance is required. It is especially suitable for applications where electrical equipment is exposed to voltage surges, such as in power distribution lines.
Technical specifications of the SIEMENS 3TX4490 3R surge suppressor element:
Breakdown voltage: 12 kV AC or DC
Peak current: 10 kA
Nominal resistance: 100 Mohm
Operating temperature: -20°C to +70°C
Applications of the SIEMENS 3TX4490 3R surge suppressor element:
Protection of electrical equipment against voltage surges
Protection of people against electric shock
Installation of the SIEMENS 3TX4490 3R surge suppressor element:
The SIEMENS 3TX4490 3R surge suppressor element is installed on a DIN rail.
Differences between the SIEMENS 3TX4490 3R surge suppressor element and the SIEMENS 3TX4490 3S surge suppressor element:
The SIEMENS 3TX4490 3S surge suppressor element is designed for use in high-temperature applications.
Operation of the SIEMENS 3TX4490 3R surge suppressor element:
When a voltage surge occurs, the varistor reduces its resistance, allowing current to flow through the resistor. The current flowing through the resistor dissipates the surge energy, protecting the electrical equipment.
Advantages of the SIEMENS 3TX4490 3R surge suppressor element:
Efficient protection against voltage surges
High reliability
Easy installation
Maintenance of the SIEMENS 3TX4490 3R surge suppressor element:
The SIEMENS 3TX4490 3R surge suppressor element does not require regular maintenance. However, it should be inspected regularly for damage. If the surge suppressor element is damaged, it should be replaced.
Here are some examples of how the SIEMENS 3TX4490 3R surge suppressor element can be used:
To protect electrical equipment against line voltage surges
To protect electrical equipment against peak overvoltages
To protect electrical equipment against electrical noise
RC surge suppressor element 24...48 V AC/24...70 V DC for connection to contactors without/with auxiliary switch blocks.
