Schneider Electric SSP1A490M7T

The single-phase relay is designed for panel mounting, with a load current capacity of up to 90A. It operates on an input voltage range of 90V to 280V AC and can handle output voltages from 48V to 660V AC. One of its key features is zero voltage switching, which makes it particularly suitable for controlling resistive loads.

Equipped with a visual LED indicator, this relay provides real-time feedback on its operational status. An alarm output is integrated to facilitate prompt responses to anomalies. The relay also includes a test button for straightforward debugging, testing, and commissioning processes. The absence of moving contacts ensures silent operation and enhances reliability.

In terms of connectivity, it features screw terminals accommodating various wire sizes, ensuring compatibility with different installation requirements. The device's thermal resistance is rated at 0.27 °C/W from junction to case, contributing to thermal management during operation. With a maximum surge current of 1200 A for 16.6 ms, it is designed to withstand transients effectively.

Compliance with multiple standards, including IEC 62314 and UL 508, ensures the relay meets necessary safety and performance criteria. The device is also rated for operation in ambient temperatures ranging from -40°C to 80°C. Its overall construction includes a thermal pad that aids in heat dissipation, further enhancing its operational efficiency.
