Temperature protectors of the C-series are high performance miniature bimetal switches which can be used in a wide range of applications and different devices. They are specifically designed for the use in electrical windings what makes them the ideal choice for the protection of motors, transformers and chokes. Protectors of this current sensitive series sense the temperature of the protected device, but also respond to the self-heating of the carrying bimetal disc. This characteristic significantly reduces temperature overswinging, if the switch is used in the windings main current circuit. The contacts open in a snap action when reaching the cut off temperature and close again automatically when the temperature decreases to the reset temperature. Numerous possible customizations extend the spectrum of applications.

Features of the series C:

  • Highest pressure resistance due to ideally domed housing and mechanically decoupled switching mechanism
  • Thermally solid connections by welded wire connections
  • Constant dimensions by front side mounted wires for all wire cross sections
  • PCB application by integrated THT and SMD terminals
  • Position- independant use by symmetrical design
  • Electromagnetic shielding by ferromagnetic housing
  • Constant resistance by optimal contact material, high contact pressure and sliding contacting
  • Consistent high quality level by automated production with integrated monitoring
