Phase sequence relay 183 528V AC, 1 C/O contact 5A RM17TG00

Phase monitoring and installation protection with RM17TG00 relay

This modular phase monitoring relay is a reliable solution for monitoring the power supply status in three-phase installations. Designed to work with networks of 183…528 V AC, it provides effective protection against the effects of phase loss, minimizing the risk of equipment damage and downtime. Its compact dimensions (17.5 mm wide) allow for easy mounting in control cabinets and switchboards, saving valuable space.

The RM17TG00 relay not only detects phase failure but also controls their sequence, which is crucial for the correct operation of many electrical devices. This ensures comprehensive protection of the installation against potential failures caused by incorrect power supply. Equipped with a 1 C/O changeover contact with a load capacity of 5A, it can be used to signal an alarm or disconnect the receiver in the event of a detected irregularity.

Functionality and application

This relay finds wide application in industrial automation – from lifting and packaging to the textile industry and water supply systems. Its phase control functions work perfectly in applications requiring stable and safe power supply, such as controlling electric motors, pumps or HVAC systems. The integrated status LED facilitates quick diagnostics and identification of problems, and the ability to set time delays allows you to adapt the relay's operation to specific application needs. Screw connection ensures secure and durable electrical connections.
