Product OverviewThe IM1202T 120A 3-phase pulse latching relay is a low-power control device engineered for high-current switching applications. It is pulse-driven — consuming energy only during the switching instant — and holds its last position via an internal permanent magnet, eliminating the need for continuous coil power. The relay is suitable for metering control, industrial panels and smart-grid equipment where reliable, low-energy contact switching is required.
