Motor thermal protection relay FRIPRO MSR01


Technical Description

The relay is used to monitor temperatures, eg in motor windings, in conjunction with thermal contacts, eg bimetal. The relay is normally closed contact at T1 - T2 dropped. However, if the contact T1 - T2 opened by an elevated temperature, so the relay is energized and the control circuit for the motor operation, eg Pump motor is permanently interrupted, even when re-closing the contacts T1 and T2. The commissioning of the normal control function can be performed only after termination of the cause of the fault and then pressing the reset button.
The switching state of the relay is optically as follows, shown:
● Green for normal operation
● Red for fault.

The output relay is a changer, max. 3A/230V.

Typical proven applications

● Monitoring of temperatures in the motor windings, ball bearing and other    Industrial plants, in rooms, refrigeration systems and other environmental    equipment,
● Humidity monitoring in conjunction with suitable humidity sensors.
