Monitoring relay RPN-1TMP-A230 864370

Motor protection monitoring relay

The RPN-1TMP-A230 monitoring relay is a device designed to monitor the temperature of a motor, specifically – short circuits in the PTC thermistor circuit. Its main task is to ensure safe motor operation by reacting quickly to potential hazards related to overheating. The device finds application in both industrial installations and household appliances where reliable motor protection is required.

Functionality and application

The RPN-1TMP-A230 relay works with a maximum of six PTC thermistor sensors connected in series. It has one changeover contact that allows controlling external circuits in case of detecting irregularities. The rated voltage of 230 AC 50/60Hz and the power supply voltage range of 230 V AC guarantee compatibility with most standard electrical installations. DIN rail mounting simplifies integration with existing infrastructure.

The device is particularly useful in applications where preventing motor damage caused by overheating is crucial, e.g. in pumps, fans, compressors or electric motors used in machines and equipment. Thanks to the fault memory function and on/off delay, it ensures stable and reliable system operation.

Technical characteristics and benefits

The RPN-1TMP-A230 relay is characterized by a solid construction and high quality workmanship. The device width of 17.5 mm allows for effective use of space in the switchgear cabinet. Contacts made of AgSnO2 ensure high durability and reliability of connections. Compliance with PN-EN 60947-8 standard confirms safety and compliance with applicable standards.

• Short-circuit protection: Fast detection of short circuits in the thermistor circuit protects the motor from damage.
