RC Element Suppression Dual AC/DC Voltage Range Protects 3RT2.2 Contactors Transient & RFI Suppression Low Voltage Applications

Product description

The Siemens 3RT2926-1CB00 is a surge suppressor utilizing an RC element (Resistor-Capacitor network) for transient voltage suppression. It is designed for dual voltage applications, supporting 24-48V AC (50/60 Hz) and 24-70V DC. This type of suppressor is effective in dampening voltage spikes and reducing RFI.

This RC element surge suppressor is specifically designed for use with Siemens 3RT2.2 contactors. It is commonly applied in control circuits where the suppression of both voltage transients and electromagnetic interference is important, such as in sensitive electronic control systems or noisy environments.

Stanlo Automation, a veteran-owned supplier of industrial surplus parts, offers the Siemens 3RT2926-1CB00. We are committed to providing quality, reliable components and excellent service to keep your automation systems running.

Frequently asked questions

What is the difference between an RC element suppressor and a varistor suppressor like the 3RT2926-1BB00?

The Siemens 3RT2926-1CB00 uses an RC element, which is effective at suppressing both fast transients and high-frequency noise (RFI). A varistor (like in the 3RT2926-1BB00) primarily targets overvoltage transients. The RC element offers a broader range of protection for sensitive circuits.
