Overview

IEC 61643-341:2001 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the requirements and test methods for thyristor surge suppressors (TSS). These components are critical in low-voltage surge protective devices designed to protect telecommunications and electronic equipment from transient overvoltages. By limiting overvoltages and diverting surge currents through clipping and crowbarring actions, TSS components help maintain system integrity and reliability.

This standard provides a comprehensive framework for defining terms, functions, configurations, performance ratings, and measurement methods for TSS components used in surge protective device assemblies.

Key Topics

Terms, Symbols, and Definitions
Clarifies the terminology and letter symbols associated with thyristor surge suppressors, ensuring consistent understanding and communication across the industry.
Basic Functions and Configurations
Details the functional principles of TSS components, including overvoltage limitation mechanisms and surge current diversion techniques like clipping and crowbarring.
Component Structure
Describes the physical and electrical characteristics of the TSS components, outlining configurations suited for integration into low-voltage surge protective devices.
Service Conditions and Fault Modes
Identifies operational environments and potential failure scenarios, providing guidelines for assessing robustness and reliability under diverse service conditions.
Rating Verification and Characteristic Measurement
Specifies standardized test procedures for verifying electrical ratings such as voltage, current capacity, and response time, as well as measuring key performance characteristics necessary for quality assurance.

Applications

IEC 61643-341:2001 is crucial for manufacturers, designers, and engineers involved in:

Telecommunications Equipment Protection
Ensures reliable suppression of surge voltages that can damage sensitive telecom circuits, thereby enhancing communication network availability.
Low-Voltage Electrical Systems
Provides guidance on selecting and verifying TSS components suited for surge protective devices in residential, commercial, and industrial low-voltage installations.
