Snap Action, Limit Switches 1HS11 Application Field and Working Principle:

1HS11 snap action, limit switches by Siemens are electrical switches used to provide overcurrent and overvoltage protection. These switches are typically used in commercial, industrial, and residential applications. The 1HS11 snap action, limit switches offered by Siemens have a wide range of features and benefits. These features and benefits provide reliable and accurate protection for electrical equipment.

1HS11 switches are suitable for switching and interrupting normal or emergency operating current in single-phase or three-phase four-wire systems and three-wire systems. These switches, with their rugged and robust design, are able to handle the rigors of industrial and commercial applications. With their hardened and corrosion resistant exterior, the 1HS11 switches are able to withstand even the harshest of conditions. These switches also feature an adjustable thermal electric breaking capacity of up to 240A. In addition to this, these switches are available in both single-pole and double-state configurations.

The 1HS11 switch is enclosed in a thermal plastic box that provides protection from water and dust. This box also contains the circuit boards that allow the 1HS11 switch to monitor current. The current is monitored through two adjustable switches that operate in two distinct modes. The first mode is the continuous-mode in which the switch continuously monitors current in order to prevent any overcurrent or overvoltage. The second mode is the intermittent-mode in which the switch is momentarily turned off and then on again at regular intervals. This mode is used for short circuit protection.

The 1HS11 switch is available with either a mechanical or electronic contact input. Mechanical contact inputs are typically used for ordinary applications, while electronic contact inputs are better suited for more specialized applications. The electronic contact inputs feature adjustable thermal electric breaking capacity and respond quickly to changes in the current.

The 1HS11 snap action, limit switch has a wide variety of applications. It can be used for the protection of motors, generators, transformers, switchgears, power plants, and off-grid systems. It is also used in industrial and commercial switching systems, as well as in residential primary and secondary air conditioning systems. The 1HS11 switch is also used in automation systems where it acts as an emergency break.

In conclusion, the 1HS11 snap action, limit switches provided by Siemens are electrical switches with a wide variety of features and benefits. These switches are suitable for use in industrial and commercial applications, as well as in residential systems. They offer reliable and accurate protection by monitoring current and responding quickly to changes in the current. Additionally, they are available in both mechanical and electronic contact inputs, giving them the flexibility to meet different application needs. The 1HS11 switch is an ideal choice for users who require reliable and accurate protection from overcurrent and overvoltage.
