Description

  • The ABB 2CTB803973R1300 OVR T2-T3 3N 20-440 P QS is an advanced surge protective device module designed to protect sensitive equipment and electrical systems from overvoltage events. Overvoltage conditions, often associated with lightning strikes or other electrical disturbances, can cause damage to electronic devices, electrical installations, and systems. Surge protective devices are essential to safely divert and dissipate excessive voltage and protect connected equipment.


  • This specific SPD module is designed to provide protection with a Type 2-T3 (T2-T3) classification. Type 2 is primarily used for protection against surges originating within the installation, while Type 3 offers additional protection against surges originating at a distance and traveling through long cables.


  • The "3N" designation signifies that it is suitable for use in three-phase electrical systems, protecting all three phases effectively. This makes it suitable for a wide range of applications, including industrial and commercial installations.
