IEC 60947-5-1 Product Description
 IEC 60947-5-1, also named Low-voltage switchgear and controlgear Part 5-1 standard, is an international standard for electromechanical control circuit devices. It defines design, rating, testing and marking rules for control circuit switching components used in industrial automation systems, supporting global certification for control cabinet and machine export projects.

This standard delivers reliable safety specification for low voltage control components. The safety specification covers devices rated up to 1000V AC or 600V DC for control, signalling and interlock functions. The safety specification regulates mechanical endurance, insulation performance and EMC anti-interference requirements. Stable safety specification guarantees consistent quality of pushbuttons, selector switches and contact blocks.

The standard defines strict performance testing for electromechanical switching elements. The performance testing includes temperature rise, dielectric strength, shock and vibration test items. The performance testing verifies contact reliability under repeated switching cycles. Accurate performance testing ensures components operate stably in harsh factory environments.

Unified marking rule brings convenient global compliance. Global compliance supports CE certification for European market access. Global compliance unifies parameter marking and technical documentation requirements. Flexible global compliance simplifies equipment inspection and acceptance for overseas OEM customers.

IEC 60947-5-1 covers push buttons, selector switches, limit switches and contact blocks, specifying construction requirements and fault protection rules. It is widely applied in control panels, packaging machines, conveyor systems and general automation equipment. The latest 2024 version is active international standard, adopted by GB/T14048.5 in China, complying with low voltage directive requirements.
