    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.

    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.
