Thermal Resistance Testing as per IEC 60309 In Chennai
Get expert IEC 60309 thermal resistance testing in Chennai with Kiyo R&D Center. Ensure your connectors meet global safety standards.
Introduction
- Industrial electrical systems must operate under demanding conditions, often involving high currents and extreme temperatures. Ensuring the resilience and safety of components like plugs and sockets is not just a recommendation—it's a regulatory requirement under IEC 60309. This international standard sets the benchmark for industrial electrical connections, focusing heavily on thermal resistance.

What Is IEC 60309?
IEC 60309 is the globally recognized standard that governs the design, performance, and safety of industrial-grade electrical connectors. It applies to systems that need to operate reliably in challenging environments—factories, construction sites, marine systems, and more.
A core part of compliance involves thermal resistance testing, which evaluates how well a connector handles heat produced during electrical operation.
Thermal Resistance Testing Under IEC 60309
IEC 60309 specifies detailed procedures to assess thermal behavior under load. These include:
Heat Rise Testing: Monitors temperature increases at contact points.
Thermal Endurance Evaluation: Tests materials and components under sustained temperature exposure.
Insulation Performance: Measures the impact of heat on insulating elements.
Design Efficiency: Evaluates the connector’s ability to dissipate heat.
