Reliable Direct Motor Starting

Direct-on-line starters apply full supply voltage directly to the motor during starting, making them a simple and effective choice for applications where the supply network and driven load can tolerate direct starting current. This makes the Chint NQ3-5.5P/230 suitable for many general-purpose motor control duties.

The enclosed design helps protect the starter components in industrial environments, while the start and stop controls allow convenient local operation. For installations requiring motor overload protection, a correctly selected overload relay should be used in line with the motor full load current and application requirements.
