Phase sequence monitor RN-35 NTRN1335

Phase monitoring and installation protection – phase sequence sensor RN-35

The phase sequence sensor RN-35 is a reliable device designed to protect sensitive electrical equipment from the effects of improper operation of a three-phase network. It protects against damage caused by phase failure, voltage asymmetry, or incorrect phase sequence – problems that can lead to production downtime, equipment failures, and costly repairs. The device is particularly useful in industrial installations, but will also work well in commercial buildings and homes with a more complex electrical installation.

Functionality and application

RN-35 continuously monitors the parameters of the three-phase network, reacting to any deviations from the norm. If an irregularity is detected, it informs about it using two LEDs: green (everything is okay) and red (error). Thanks to the adjustable setpoint (170-200V), the sensor's sensitivity can be adjusted to the specific requirements of the installation. A relay output with a load capacity of up to 10A allows connection to a control or alarm signaling system. Mounting on a standard 35 mm DIN rail is quick and easy, making it easy to integrate with existing electrical infrastructure.

Design and characteristic features

The device has been designed with durability and reliability in mind. The compact, single-module housing made of plastic provides resistance to mechanical damage. The sensor is resistant to short-term voltage drops, which minimizes the risk of false alarms. It meets safety standards (IP20), which guarantees protection against accidental contact. Thanks to this, RN-35 is an investment in the safety and continuity of operation of the electrical installation. The device manufactured by NOVATEK-ELECTRO is characterized by high quality workmanship and is appreciated by installers for its ease of installation and reliable operation.
