KTSB 087 / R series bimetal thermostats are designed as two-state regulators (ON / OFF control) that compare the preset and instantaneous temperature and immediately disconnect the contact when a set temperature is reached. The required switching temperature is defined according to customer needs by the selection of a bimetallic thermal cutout and cannot be changed.
The KTSB 087 / R series bimetal switches consist of a stainless steel housing containing a bimetal switch (thermal cut-off) and a power cable.
KTSB 087 / R series bimetal switches are used to signal a temperature overshoot in various applications, eg. to protect transformers, semiconductor power stages, motors and powerful batteries. The KTSB 087 / R series bimetal switches are intended for operation in chemically non-aggressive environments.
