NHP has announced the arrival of the Sprecher + Schuh RT7-E1 (basic) and RT7-E2 (enhanced) thermistor relays.

These compact 22.5mm wide, over-temperature monitoring relays are an innovative extension to Sprecher + Schuh's motor control and protection product range.

The multi-voltage and multi-featured RT7 provides an independent, reliable and accurate method of thermal protection. It boasts intelligent in-built fault diagnosis abilities, combining over-temperature detection and protection facilities.

Not only does the RT7 trip reliably in the case of an over-temperature situation, but also in the event of a short or open circuit in the sensor measuring circuit.

Trip indication on the LED can distinguish between over-temperature, short circuit and open circuit trip conditions. The RT7, therefore, is an economical choice for protecting equipment investments and minimising production downtime.

Additionally, the RT7-E2 enhanced version has the ability to store the state of the relay before a power failure for an unlimited amount of time.

The unit comprises a trip signaling contact that only closes when a trip condition is encountered.

The RT7's supply voltage range, standard in both models (24 to 240 V ac/dc), adds further to the RT7's application versatility, actively reducing inventory.

The RT7 thermistor protection relay is suitable in many applications where accurate over temperature monitoring is required. Its global approval and IP20 rated enclosure guarantees safety and avoids contact with live parts.

NHP offer this product and the wider Sprecher + Schuh motor control and protection range, guaranteeing support and technical advice through the length of application.
