Limit switches are a type of industrial electrical device used to turn on and off electrical loads. They take the form of a small mechanical switch that is operated manually or automatically and are used in applications where precise control over the switch is important. The 1EN330-R3 is a limit switch developed by the company ABB for a range of industrial applications.

The 1EN330-R3 is a snap-action limit switch designed for use in difficult to access locations. It features adjustable travel and overtravel stop screws, allowing the user to limit the amount of travel available in a switch before engaging the contacts. This means that it can be used in applications where reliability and repeatability are important. The 1EN330-R3 is also designed to be easy to maintain, with an accessible terminal block and a robust housing.

The 1EN330-R3 features an adjustable switching force, allowing it to be tuned for a range of applications. The switch is actuated by the movement of a plunger that is mounted to the electrical load, and automatically returns to the off position when the plunger is released. This allows repeated activation of the switch over long periods of time without suffering from wear or accumulated debris. When the plunger is released, the contacts revert to their original position, thus preventing the device from staying on.

The switch is designed to be used in a range of industrial applications, including controlling motors, fans, valves and pumps. It is also suitable for use in food processing machines and other applications where cleanliness and accuracy are important. The 1EN330-R3’s low cost, reliable operation and adjustable switching force make it an ideal choice for many applications.

The 1EN330-R3 switch is a reliable, low-cost solution for a range of industrial applications, offering adjustable switch travel and adjustable switching force for improved accuracy and performance. Its robust construction and easy access terminal block make it easy to maintain, while its adjustable overtravel stop screw provides adjustable repeatability for long-term reliability and accuracy. The 1EN330-R3 is an ideal choice for many different applications.
