3TX4490-3G SIEMENS

The 3TX4490-3G surge suppressor from Siemens is a varistor designed to protect sensitive electronic equipment from voltage spikes and transient surges. It is specifically engineered for use with contactors, both with and without auxiliary switch blocks, providing a reliable safeguard against overvoltage events. This surge suppressor is suitable for AC circuits up to 48 V and DC circuits ranging from 24 to 70 V, offering versatile protection across different voltage levels. By clamping voltage surges, the varistor prevents damage to connected devices, ensuring operational continuity and minimizing downtime. Its plug-on design allows for easy installation and integration into existing systems, simplifying the process of enhancing surge protection. The 3TX4490-3G effectively absorbs excess energy from transient voltages, diverting it away from sensitive components. This helps to extend the lifespan of contactors and other connected equipment by mitigating the harmful effects of electrical disturbances. It provides a cost-effective solution for improving the reliability and resilience of electrical systems against voltage-related issues. This surge suppressor is an essential component for maintaining stable and protected operations in industrial and commercial applications.
