We, Digital and Smart Grid Enterprises, offer a comprehensive range of Hitachi Energy Auxiliary Relays designed to ensure reliable performance in electrical protection, control, and industrial automation systems. These relays perform essential functions, including tripping, blocking, interlocking, signalling, contact multiplication, and circuit breaker position indication. Moreover, Hitachi auxiliary relays deliver fast operating speeds, low power consumption, compact construction, and high contact reliability. As a result, they are suitable for demanding applications where conventional industrial relays may not provide the required operating speed or contact-breaking capacity.
Our product portfolio includes several Hitachi Auxiliary Relay models, such as RXMA, RXMB, RXMC, RXMD, RXME, RXMH, RXMM, RXMN, RXMS, RXMT, RXMVB, and RXMVC. Each series addresses specific application requirements, ranging from general-purpose auxiliary functions and high-speed tripping to heavy-duty switching, bistable operation, and high-burden tripping. Furthermore, at Digital and Smart Grid Enterprises, we supply Hitachi auxiliary relay solutions for substations, power utilities, industrial plants, protection panels, and electrical infrastructure projects. Through these solutions, we help customers improve protection reliability, strengthen operational safety, and achieve efficient control system performance.
