ABB 2CTB414911R5100 Surge Protective Device Module

Description

• The ABB 2CTB414911R5100 is a Surge Protective Device (SPD) module that is designed to safeguard low-voltage consumer systems from surge voltages and transient overvoltages. This SPD module is classified as Type 1 (formerly known as Class B) and Type 2 (formerly known as Class C) according to the IEC 61643-11 standard. It offers effective protection against surges caused by external factors, such as lightning strikes, and internal factors, like switching operations.
