Extend the lifespan of DC contactors! Prevent troubles in advance with the timing of replacement and measures.

The lifespan of DC contactors varies greatly depending on "operating conditions"! We will also introduce the main factors that shorten electrical lifespan.

The lifespan of DC contactors varies greatly depending on the usage environment and load conditions. Generally, there are "mechanical lifespan" and "electrical lifespan," where the former is determined by the wear of structural components, and the latter is determined by contact wear due to arc discharge. However, the electrical lifespan cannot be expressed as a uniform value. The lifespan can change several times to several tens of times due to slight differences in conditions such as the type of load, frequency of operation, temperature and humidity, and the presence or absence of surge protection. At Olbright, we emphasize this realistic variability and do not list a "standard value for electrical lifespan" in our data sheets. We recommend selection and consultation based on actual usage conditions. *For detailed content of the column, please refer to the attached PDF. For more information, feel free to contact us.
