Three-phase control relay 380-480V AC 2 C/O

This Zelio RM22-TR relay allows for phase and under/overvoltage monitoring in three-phase networks. This modular multifunctional three-phase control relay is ideal for monitoring electrical values in industrial and building control panels. It is applicable to a wide range of industrial automation applications such as lifting, packaging, lifts, textile, or water. It has one of the slimmest formats on the market, at 22.5 mm wide, allowing for flexible and easy installation on a DIN rail, occupying the same space as any 1-pole modular DIN device. It also features a diagnostic button, sealable cover, and simple, precise adjustments via screw regulators. It provides automatic shutdown management and fault information to the user for quick fault identification and resolution. It is a multifunction controller for a wide variety of selectable options in automated systems with integrated logic, ideal for retrofitting older installations without using a PLC.
