Harmony RM17TE00 Multi-Function 3-Phase Supply Control Relay (208-480 VAC)
The RM17TE00 is a sophisticated Harmony Control Relay designed for comprehensive monitoring of 3-phase power supplies. This multi-function control relay provides critical protection for motors and other sensitive equipment by detecting various fault conditions, including undervoltage and overvoltage (in window mode), asymmetry, phase sequence, and phase failure.
Housed in a durable, self-extinguishing plastic housing, the relay features a single changeover output contact (1 C/O or SPDT) with a nominal current rating of 5 A (AC/DC) and a switching capacity of 1250 VA. Its wide measurement range of 208 to 480 VAC makes it suitable for diverse industrial applications. The relay offers simple and accurate adjustments for parameters like time delay (0.1-10s) and voltage thresholds, ensuring quick and easy setup.
It's designed for 35 mm symmetrical DIN rail mounting and includes local LED indicators for power (green) and relay status (yellow). The RM17TE00 is a self-powered unit and comes with various certifications including UL, CSA, and CE marking, affirming its compliance with global standards.
