Description
The motor protection relay MK 9052 is used to prevent thermal motor overload. Special PTC thermistors (PTC resistors) are used as temperature sensors for motor protection. Up to 6 sensors can be connected in series, which, when a fixed resistance value is reached, cause the output relay of the MK 9052 to drop. An LED indicates the switching state. The motor protection relay operates according to the closed-circuit principle and monitors itself against wire break Note that when the power is switched on, the phase voltage is briefly present at terminals 12 and 22 until the output relay has responded.
