The service life of an Air Circuit Breaker depends on the operating and environmental conditions on site. An ACB is often exposed to mechanical and electrical stresses and thus
suffers gradual degradation during use, increasing the possibility of malfunct ion.
Preventative maintenance and periodical inspection are important for reducing the risk of malfunction and extending the service life of an ACB.
The frequency of maintenance and inspection varies depending on operating factors on site such as environmental conditions, the number of close or trip operations, the magnitude of breaking current. Terasaki's preventative maintenance service is available to ensure integrity of electrical supplies. From the range of services available we tailor a program around the structure of the electrical system on site. Circuit breaker maintenance work can be carried out at the site location or at our specialised facilities in Glasgow.
