Product description ST01 as temperature switch for 3-phase electric motors

The ST01 as a temperature switch for 3-phase electric motors of the ST01 series offers a power class from 1.6A to 7.5A and is closed as standard. It has an automatic reset function and robust Mylar-Nomex insulation.

PRODUCT LAUNCH

The ST01 temperature switch for 3-phase electric motors is characterized by its robust design, which was specially developed for use in industrial environments. It is equipped with an integrated ceramic cover plate for the fixed silver contact. The movable contact is firmly connected to a cross-shaped spring washer, which in turn is connected to a conductive housing.

STRUCTURE AND FUNCTION

When the nominal operating temperature is reached, the bimetallic disk in the ST01 deforms, causing the circuit to be interrupted. After cooling down and reaching the defined reset temperature, the bimetal disk and the spring washer return to their initial position. This enables the moving contact to be reconnected to the fixed silver contact and ensures that the circuit is restored.

FUNCTIONAL FEATURES

  • Rated current class: 1.6A to 7.5A
  • Automatic reset for continuous operation
  • Robust Mylar-Nomex insulation for a high level of safety
  • Integrated ceramic cover plate protects the fixed silver contact
  • Cross-shaped spring washer and conductive housing for reliable connection
  • Suitable for use in 3-phase electric motors and industrial applications
