STEGO Thermostat switch contact maker STS 011

THERMOSTAT SWITCH No Normally open

STS 011
The mechanical thermostat closes when the temperature rises. Used for regulating filter fans, heat exchangers, coolers or switching signal devices in the event that the temperature limit is exceeded. The bimetal thermostat has a small hysteresis.
  • Engaging adjustment dial
  • Small hysteresis allows for precise regulation
  • Optimised air inlets
  • High switching capacity

¹ When connecting with stranded wires, wire end ferrules must be used.

Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may change. This can lead to a voltage drop and/or self-heating of the contacts.
