IEC609473

IEC609473 is not a recognized IEC standard number. It appears to be a typographical error or misreference, potentially pointing to another standard within the IEC 60947 family. The IEC 60947 series is an internationally adopted set of standards for low-voltage switchgear and controlgear, maintained by the International Electrotechnical Commission (IEC).

Overview

The IEC 60947 family covers equipment used to switch, control, and protect electrical circuits at low voltages, typically up to 1000 V AC or 1500 V DC. The purpose of the series is to establish safety, performance, reliability, and interoperability requirements for a range of devices used in distribution and automation systems. The standards are widely incorporated into product specifications, testing regimes, and certification programs.

Scope and typical devices

The 60947 family encompasses multiple device categories used in electrical installations, including switches, contactors, motor-starters, circuit-breakers, protective devices, and related control components. Each part focuses on specific device types or applications, with requirements for electrical ratings, mechanical operation, dielectric strength, thermal performance, electrical endurance, and environmental conditions.

Conformity and usage

Products conforming to IEC 60947 are designed to meet standardized safety and performance criteria, enabling cross-border compatibility and safer operation in electrical systems. Manufacturers typically provide certification or test reports indicating compliance with the relevant 60947 parts, and end users apply these standards when specifying equipment and evaluating suppliers.

Clarification

If you intended a specific part number, such as IEC 60947-1 or IEC 60947-3, please provide the exact designation. For authoritative information, consult the IEC or national standards bodies.
