Recyclability potential, in %
information_stroke
The calculation of the recyclability potential relies on the scenario "France - parts are shredded" of TR62635 considering all parts in the product and materials recyclability. We recognized that this may not always allow comparison with other competitor offers on the market and are waiting for a common standard to be published end of 2026.

Description
arrow2_down
This Harmony RM17-UB relay allows monitoring of voltage control in 3-phase networks. This modular multi function 3-phase voltage 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 slimmest form-factors with 17.5mm 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 sealable cover, 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.
