概要

FEATURES

The advantages of using normally closed DC contactors are many and significant. One of the main benefits is safety. By keeping the circuit closed when power is removed, these contactors ensure that the load remains energized, which is particularly important in applications that require continuous power. This feature is essential in environments where equipment must remain operational at all times, such as in critical infrastructure or medical facilities.
