How does the automatic reset function operate in the relay?

The automatic reset function allows the relay to re-energise once the monitored temperature falls below the set threshold after an overheating incident, ensuring minimal downtime and continuous operation without manual intervention.

What types of sensors can be connected to the relay for monitoring?

The relay is compatible with PTC type A sensors, which can be incorporated directly into motor windings to provide precise temperature readings, ensuring accurate monitoring for preventive measures.

Can this relay differentiate between fault types during operation?

Yes, the device features dynamic interrupted wire detection. It distinguishes between overtemperature conditions and an interrupted wire in the measuring circuit, providing relevant fault information through LED indicators.

What is the reaction time of the safety functions integrated into the relay?

The safety function of the monitoring relay has a rapid reaction time of less than 100 milliseconds, ensuring quick response to any temperature anomalies for effective protection of motors.
