The Siemens 3RT2926-1BB00 is a robust surge suppressor designed to enhance the performance and longevity of motor contactors, specifically those of size S0. This component utilises a varistor to effectively manage and mitigate voltage spikes, ensuring the protection of sensitive control circuits against transient surges. It is compatible with both alternating current (AC) and direct current (DC) control supply voltages, accommodating a range from 24 to 48 volts for AC and 24 to 70 volts for DC.
Crafted with reliability in mind, the 3RT2926-1BB00 operates efficiently within a broad ambient temperature range, from as low as -25°C to as high as +60°C during operation, and can withstand storage temperatures from -40°C to +80°C. This flexibility ensures consistent performance across various environmental conditions.
Installation is straightforward, thanks to its clip-on mounting design, allowing for quick and secure attachment to the contactor. The compact dimensions of the surge suppressor, with a width of 30mm, a height of 19mm, and a depth of 12mm, make it an unobtrusive addition to any electrical setup.
The 3RT2926-1BB00 is certified with CE, UL, CSA, and CCC approvals, reflecting its compliance with international standards and its suitability for a wide range of industrial applications. Whether used in control panels, machinery, or automation systems, this surge suppressor is an essential component for safeguarding electrical equipment from voltage transients.
