Fuseholders

JP60030-3CORA is an application field and working principle developed for fuseholders. It is a set of standards developed by the International Electrotechnical Commission (IEC) to ensure safety and reliability when these fuseholders are used. The standards for fuseholders covered by these applications include mechanical, electrical and thermal design, and other properties that should be considered when designing these components. The specific application field and working principle covered by the standard are described below.

Application Field

The application field of JP60030-3CORA includes fuseholders for single-pole or multi-pole applications, both in the power distribution and control systems. It can be used for both indoor and outdoor installations, including applications in hazardous areas. The standard includes requirements that relate to the material used to manufacture the fuseholder and the construction of the fuseholder. It also covers tests that need to be performed on the fuseholder to ensure that it will be able to withstand the intended operating conditions.

Working Principle

The working principle behind JP60030-3CORA is to ensure that fuseholders are designed and constructed in such a way that they can safely and reliably operate in their intended application. The standard includes requirements for mechanical construction, electrical connection and thermal design, and other properties. Requirements for the mechanical construction of the fuseholder include resilience, strength and durability, and the construction should be in accordance with the relevant parts of the standard. Electrical connections should be made in accordance with the standard and should be set up so that the current is correctly distributed. Requirements for the thermal design include ensuring adequate ventilation, making sure the fuseholder does not overheat, and conductivity to prevent dangerous electric shocks.

Testing

The standards may also include specific tests that need to be performed on the fuseholder to verify that it meets or exceeds the requirements. Tests are usually conducted to verify the mechanical and electrical construction, as well as the thermal design. Tests can also be conducted to verify the safety of the fuseholder and to ensure that it meets all the applicable requirements. Testing should be done in accordance with the relevant parts of the standard, and in most cases the test results need to be documented and approved by a relevant authority before the fuseholder can be used.
