Monitoring relays

Product catalog summary

Overview: This document provides technical specifications and functionalities for the RPN series of monitoring relays, specifically designed for AC voltage and current monitoring in 3-phase and 1-phase networks.

Specifications:

RPN-1VF-A400: Designed for AC voltage monitoring in 3-phase networks with a rated input voltage of 3(N)~ 400/230 V AC at 50/60 Hz. It features a single changeover contact with a rated load of 12 A / 250 V AC or 12 A / 24 V DC. Dimensions are 90(98.8) x 17.5 x 64.6 mm, and it uses universal screw terminals.
RPN-1A..-A230 Series: These relays are for AC current monitoring in 1-phase networks with a supply voltage of 230 V AC. They offer various measuring inputs ranging from 0.5 A to 16 A, with corresponding overload capacities. They perform functions such as overcurrent and undercurrent monitoring with optional fault latching.
RPN-1TMP-A230: This relay is for motor temperature monitoring, supporting up to 6 PTC thermistor sensors in series, with a supply voltage of 230 V AC.

Functionalities:

Voltage Monitoring Relays: Perform functions like phase failure (LOST D), asymmetry (ASYM D), and phase sequence monitoring (SEQ D) with fixed or adjustable asymmetry ranges.
Current Monitoring Relays: Include functionalities for overcurrent (OD), undercurrent (UD), and window function monitoring (WD), with options for fault latching.
Temperature Monitoring: Monitors motor winding temperature with fault latching capabilities.

Key Features:

All relays have a single changeover contact output.
Overload capacity is ≥1.2 times the nominal voltage for voltage monitoring relays.
Relays are equipped with universal screw terminals for easy installation.
