The ST11 series switchgear is an innovative technical solution used in monitoring and controlling the temperature of electrical equipment and motors. It consists of a spring snap disc, a bimetal disc, a movable contact and a stationary silver contact. The use of materials with different thermal expansion enables precise and reliable temperature monitoring and control.
The ST11 series is characterized by its form-fit and self-aligning design, clamped between the bottom of a current-conducting housing and a steel contact cover insulated from it. This ensures optimum contact between the various components and guarantees reliable operation. The spring snap disk serves as a current transmission element and also carries the moving contact. The continuous, constant contact pressure relieves the bimetal disc of current flow and self-heating.
The bimetal disc is the central element of the switchgear and reacts to the ambient temperature in the device to be protected. When the nominal switching temperature is reached, the bimetal disc snaps into its reverse position and presses the spring snap disc down. This opens the contact abruptly and interrupts the temperature rise of the device to be protected. If the ambient temperature now drops, the bimetallic disk snaps back into its initial position when a defined reset temperature is reached and the contact is closed again. This process is performed continuously and automatically, ensuring reliable monitoring and control of the temperature.
The ST11 series is particularly suitable for use in industry, especially in electronics, automotive and refrigeration engineering. Thanks to precise temperature monitoring and control, high operational reliability and longevity of the devices and motors are ensured. In addition, the ST11 series is easy to integrate and offers high accuracy and reliability.
In summary, the ST11 series switchgear is an innovative technical solution that provides precise and reliable temperature monitoring and control. The use of materials with different thermal expansion and a form-fit, self-aligning design ensures high operational reliability and durability of the devices and motors. The ST11 series is easy to integrate and offers high accuracy and reliability.
