Schneider Electric Harmony Relay Series Solid State Relay Panel Mount 75A Load 660V AC Load 280V AC Control SSP1A475M7T

Schneider Electric SSP1A475M7T Harmony Relay Series is a robust solid state relay designed for panel mount applications with a maximum load current capacity of 75A and maximum load voltage of 660V AC. It supports a control voltage up to 280V AC and offers zero voltage switching functionality that minimizes electrical noise and extends equipment life. The relay features SCR output ensuring silent and reliable switching without mechanical parts.

This relay has compact dimensions (44.5mm length, 34.29mm width, and 58.9mm height) and an operating temperature range from -40°C to 80°C, suitable for demanding industrial environments. The screw terminal type ensures secure connections in panel mount setups. Its IP20 rating provides protection against solid objects, making it suitable for industrial machines, packaging machinery, HVAC systems, textile machines, medical and building equipment.

The SSR includes a smart diagnostic feature with signal alarm output for easy troubleshooting, reducing downtime and operational impact. It is maintenance free, supports high switching frequency, and provides sustainable performance in harsh conditions with resistance to shock and vibration. The low off state leakage current (1mA) and 8pF capacitance optimize operational efficiency.

Manufactured in Mexico, this relay complies with stringent standards including UL, CE, CSA, RoHS, EAC, REACH, and EN/IEC 62314. It is ideal for controlling single phase industrial loads where precise, silent, and reliable switching is required.

Designed for panel mount installation with secure screw terminals. Zero voltage switching for reduced electrical noise and efficient control. High reliability with solid state SCR output and no moving parts. Wide temperature operating range ensures versatile industrial application.
