IEC 60898 Clause 9.13 Low Energy Pendulum Impact Tester For Circuit Breaker Mechanical Testing
Product Overview
This Pendulum Impact Tester is designed to assess the mechanical resistance of electrical devices under low-energy impact conditions. It is suitable for circuit breakers, socket outlets, plugs, and related accessories, fully complying with IEC 60898 standards.
The equipment delivers a precise pendulum strike to the specimen, providing a repeatable and measurable impact to verify the structural integrity and reliability of electrical components.
Working Principle
The device employs a calibrated pendulum mechanism to generate a predetermined impact energy. The pendulum is released from a set height, striking the sample at the intended location.
This design allows engineers to observe material response, deformation, or failure under controlled conditions, ensuring accurate verification of the product’s mechanical durability.
The frame is robust and rigid, ensuring the impact energy is consistently delivered across repeated tests, while minimizing vibration or measurement error.
