This Harmony RM17JA relay allows monitoring of current control in single-phase networks. This modular multi-function single-phase current control relay is ideal for monitoring electrical values in industrial and building control panels. The Harmony Control Relays for single-phase systems operate within a voltage range of 220 to 240V AC. It has one of the market medium form factors with 17.5 mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 3-pole DIN device. It also offers a sealable cover, simple and precise settings with screw trimmers. It provides automatic shutdown management and fault information to the user for quick fault identification and troubleshooting. This is designed to monitor overcurrent and undercurrent conditions within a range of 0.5 to 10A and weighs 70 grams. It applies to a wide range of industrial automation applications such as hoisting, mining, packaging, lifts, textile, and water. It conforms to international standards, cULus, DNV-GL, CE, UKCA, CCC, and RCM certifications. Multi-function controller for a wide choice of selections in hard-wired logic automated systems, ideal for the refurbishment of old installations without using a PLC.
