IVY Latching Relays

IVY specializes in the development and manufacturing of high-quality latching relays. We offer a line of latching relays spanning from 32A to 200A for single-phase Two-phase and three-phase switching purposes. our relays meet the industry's highest performance standards and offer the best value in the energy management market. In particular, we have developed an innovative relay switch-motor latching relay. Compared with magnetic latching relay, motor latching relay with 500mT permanent magnetic immunity, prevent contacts from being interfered by magnetic fields. And, the size is much smaller.
