3RT1916-1BC00 SIEMENS

The 3RT1916-1BC00 is a varistor designed to provide surge suppression for contactors, specifically size S00. It offers protection against voltage spikes within the range of 48 to 127 V AC and 70 to 150 V DC. This varistor is intended for direct plugging onto the contactor, simplifying installation and ensuring a secure connection. As a phased-out product, the recommended successor is the SIRIUS 3RT2, with the preferred replacement type being 3RT2916-1BC00. Utilizing a varistor like the 3RT1916-1BC00 or its successor is crucial for safeguarding sensitive electrical components from potentially damaging voltage surges. These surges can originate from various sources, including lightning strikes, power grid fluctuations, or the switching of inductive loads. By diverting excess voltage away from the contactor, the varistor helps to extend the lifespan of the equipment and prevent costly downtime. The 3RT2916-1BC00 offers enhanced performance and reliability compared to its predecessor. Always consult the manufacturer's documentation to ensure compatibility and proper installation procedures are followed. Choosing the correct surge suppressor is paramount for maintaining the integrity of your electrical system.
