Description

This Harmony RM22TG control relay allows monitoring of power supply circuits in 3-phase networks. This modular 3-phase control relay is ideal for monitoring of electrical values in industrial and building control panels. It applies to a wide type of industrial automation applications such as hoisting, packaging, lifts, textile, water. It has one of market slim form-factors with 22.5mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device. It also offers a selectable memory function, integral LED for indicating control status, sealable cover, with simple and precise settings with screw trimmers. It provides automatic shutdown management and fault information to user for a quick fault identification and troubleshooting. Multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC. 0 0 0 0 0 0 0 0 0 0 0 0

Features

Part of the Harmony Control Relays range, the RM22TG20 is purpose-built to track both phase sequence (rotation direction) and phase failure (loss of two or more phases) across 3-phase networks. This instant power supply monitoring protects expensive downstream three-phase motors from running in reverse or single-phase, preventing catastrophic mechanical damage and coil burnouts
This self-powered monitoring module operates seamlessly over a broad measurement spectrum spanning 183 V to 528 V AC across 50/60 Hz networks. It naturally covers standard industrial infrastructure voltages like 208 V and 240 V allowing you to standardize on one inventory component for diverse multi-voltage panel projects.
The relay integrates a heavy-duty 2 C/O (changeover, DPDT) contact configuration with a maximum switching current of 8 A at 250 V AC. These independent, cadmium-free contacts provide plenty of switching capacity to simultaneously drop power to an upstream contactor coil and trip a localized indicator light when a phase fault strikes.
Housed in an ultra-slim 22.5 mm wide modular enclosure, this relay occupies the same footprint as a standard 1-pole circuit breaker on a symmetrical 35 mm DIN rail. This compact profile frees up vital panel real estate, simplifying refurbishment projects and allowing machine builders to pack advanced protection into tight layouts.
Featuring an ultra-fast internal response time of 200 milliseconds or less, the system isolates anomalies before they can induce mechanical strain on active machinery. Clear front-facing dual LEDs give technicians instant diagnostic clarity a green light confirms incoming power is healthy, while a yellow indicator confirms the active status of the output relay.
Built with a robust, self-extinguishing plastic housing, the module features a rugged electrical lifespan up to 100,000 cycles and mechanical endurance of 10 million operations. The design includes an option for a sealable, transparent front cover that stops unauthorized setting adjustments while maintaining an IP20 terminal and IP50 front-face finger-safe barrier.
