Description

This Harmony RM22TR 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 and voltage variation 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

The Schneider Electric RM22TU23 Harmony control relay continuously tracks phase loss, phase sequence, and undervoltage conditions across a 380V to 480V AC measurement range. By instantly identifying these critical power line faults, it triggers an automatic shutdown to safeguard high-value downstream machinery like industrial motors, pumps, and packaging equipment against catastrophic phase failure burnout.
Featuring an ultra-slim 22.5mm width form-factor, this DIN rail monitoring relay occupies the exact same footprint as a standard 1-pole circuit breaker. This streamlined profile optimizes your rail space, simplifying hard-wired logic installations and panel retrofits without forcing you to scale up to an expensive, oversized enclosure.
Engineered with 2 C/O (changeover) DPDT output contacts rated at 8A and 250V AC, this control relay offers the multitasking capability required for automated industrial environments. You can dedicatedly hard-wire one contact to immediately cut power to the motor starter coil while utilizing the second contact to report the fault condition directly to your PLC or localized alarm system.
Built to conform to stringent international standards including IEC 60255-1 and UL 508, this Harmony series relay carries UL, CSA, CE, and RCM certifications. This comprehensive compliance guarantees long-term durability with a mechanical lifespan of up to 10 million cycles, making it fully approved for demanding commercial lifts, hoists, and municipal water applications.
