IEC 60898-1: 2019 Electrical accessories – Circuit-breakers for overcurrent protection for household and similar installations – Part 1: Circuit-breakers for a.c. operation

Overview
IEC 60898-1:2019 specifies requirements for circuit breakers intended for overcurrent protection in household and similar installations. These devices are designed for alternating current (AC) circuits with rated voltages not exceeding 440V and rated currents up to 125A. The standard ensures that circuit breakers can interrupt overload and short-circuit currents reliably, safeguarding electrical installations and connected equipment.

Key Provisions
The standard outlines detailed specifications for classification, markings, performance requirements, and testing methods of circuit breakers. It covers critical aspects such as temperature rise, short-circuit capacity, mechanical durability, and operational reliability under normal and fault conditions. IEC 60898-1:2019 serves as a technical foundation for manufacturers and testing bodies to ensure product consistency, safety, and compliance in household and similar environments.
