Maintenance and Testing

Maintenance of low-voltage circuit breakers, the specific cycle should be judged according to the operating environment and operating frequency. Visual inspection and mechanical testing every 1-2 years if stable, clean and infrequently used. But if you are using it in harsh industrial environments, or very critical applications, it is recommended that you perform a thermal imaging inspection every year to check for hot spots, and a comprehensive electrical test every 3-5 years.

Ceho recommends insulation resistance check, contact resistance measurement and injection test. If you find specific problems or feel that you need to replace and upgrade, you can contact us and obtain technical support.
