Schneider Electric SSP3 Harmony Solid-State Relays
Schneider Electric SSP3 Harmony Solid-State Relays (SSRs) provide three-phase load switching with 25A or 50A load ratings and are suitable for harsh environments. These compact, panel-mount SSRs use solid-state technology without moving contacts, providing silent operation, frequent switching, resistance to shock and vibration, and minimized maintenance needs. The SSP3 series includes zero-voltage and random-voltage switching options and three control input choices: 4VDC to 32VDC, 18VAC to 36VAC, and 90VAC to 280VAC. Schneider Electric SSP3 Harmony relays feature a green LED to indicate input status, and the factory-installed thermal pad supports reliable heat transfer during installation.
