B Series Bimetal Snap-Action Temperature Switches

Microtherm Sentronic B Series Bimetal Snap-Action Temperature Switches feature a bimetallic snap-disc with a fixed switching temperature as the switching mechanism. The function of these switches includes typically closed or normally open operation, commonly used as a temperature limiter to protect or control devices from overheating. The B Series offers a current rating of 1-13A max to 30A, up to 10,000 switching cycles, with various packaging options. These switches also feature non-current carrying brass contacts. Microtherm Sentronic B Series Bimetal Snap-Action Temperature Switches are ideal for motors, transformers, electronics, sensors, pumps, converters, and more applications.
