What is EN 60947-2 ?

Title: What is EN 60947-62? A Comprehensive Technical ArticleEN 60947-62 is a technical standard published by the International Electrotechnical Commission (IEC) that outlines the requirements for low-voltage switchgear and controlgear devices. This standard is part of a series of IEC standards designed to ensure the safety and performance of electrical equipment. In this article, we will delve deeper into the key requirements and tests of BS EN 60947-62.

BS EN 60947-62 is an international standard that aims to ensure the safe operation and performance of circuit-breakers. These devices are crucial for protecting electrical circuits from overload, short-circuit, and other faults that could lead to damage or fire. The purpose of this standard is to provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards.

Key Requirements and TestsBS EN 60947-62 has several key requirements and tests that manufacturers must meet to ensure compliance with the standard. These requirements include:

* Safety: The standard must ensure the safety of the users, workers, and the environment.

* Reliability: The standard must ensure the reliability of the circuit-breakers under various operating conditions.

* Performance: The standard must ensure that the circuit-breakers perform as expected under various tests and loads.

* Environmental Stability: The standard must ensure that the circuit-breakers are stable and perform well in various environmental conditions.

* Electrical Characteristics: The standard must ensure that the circuit-breakers have the correct electrical characteristics, including voltage, current, and switching characteristics.

* Safety Characteristics: The standard must ensure that the circuit-breakers have the correct safety characteristics, including the ability to interrupt the flow of current in case of an overcurrent.

Test RequirementsBS EN 60947-62 has several tests that manufacturers must meet to ensure compliance with the standard. These tests include:

* Electrical Overload Test: The standard requires manufacturers to perform a series of electrical overload tests to ensure that the circuit-breakers can handle the expected load and currents without overheating or failing.

* Short-Circuit Test: The standard requires manufacturers to perform a series of short-circuit tests to ensure that the circuit-breakers can handle the expected short-circuit currents without overheating or failing.

* Overcurrent Protection Test: The standard requires manufacturers to perform a series of overcurrent protection tests to ensure that the circuit-breakers can handle the expected current draw without overheating or failing.

* Heat Test: The standard requires manufacturers to perform a series of heat tests to ensure that the circuit-breakers can handle the expected heat generated under various operating conditions without overheating or failing.

* Environmental Test: The standard requires manufacturers to perform a series of environmental tests to ensure that the circuit-breakers can withstand various environmental conditions, including high temperature, low temperature, and humidity.

ConclusionBS EN 60947-62 is a technical standard that outlines the requirements for low-voltage switchgear and controlgear devices. It is designed to ensure the safe operation and performance of circuit-breakers, while also meeting high safety and performance standards.
