Siemens 3RT2926-1CB00 Surge Suppressor, RC Element, 24-48V AC / 24-70V DC for 3RT2 Contactors Original Brand New

Overview: Siemens 3RT2926-1CB00 RC Surge Suppressor

The Siemens 3RT2926-1CB00 is an essential protection module, an RC surge suppressor designed specifically for the 3RT2.2 generation of Siemens power contactors. This compact, high-performance accessory is critical for industrial control applications, ensuring the longevity and reliable operation of your contactors by dampening harmful voltage spikes that occur when switching inductive loads.

The module is versatile, accommodating both AC and DC control voltages: 24-48 V AC (50/60 Hz) and 24-70 V DC. Integrating this RC element is a simple, plug-and-play process, eliminating the need for complex wiring and enhancing overall system safety.

Function

The primary function of the 3RT2926-1CB00 is to protect the electronic components and control circuits from transient overvoltages. When the coil of a 3RT2.2 contactor is de-energized, it generates a high-energy voltage spike (back-EMF). The integrated RC element acts as a filter, safely absorbing and dissipating this energy, preventing damage to PLC outputs, relays, and other sensitive upstream components.

Benefit

• Enhanced System Reliability: Prevents contactor coil failure and minimizes nuisance trips caused by voltage transients.

• Reduced Downtime: Protecting control electronics means less component replacement and higher operational uptime.

• Versatile Voltage Range: Covers the most common industrial control voltages, supporting both 24V DC and 24V/48V AC systems.

• Simple Installation: Designed to snap directly onto the 3RT2.2 contactor, making installation and maintenance fast and easy.

• Genuine Siemens Quality: Ensures perfect fit and reliable performance, maintaining the high standards of the SIRIUS 3RT2 line.
