Crydom Solid State Relay, 125A Load, Panel Mount, 530V AC Load, 32V Control HD48

The Crydom HD48 Series Solid State Relay HD48 is engineered for demanding industrial electrical control and automation applications where reliable high current switching is essential. With a load current capacity of 125A and operational load voltage up to 530V AC, this panel mount SSR is suitable for controlling heavy-duty equipment including motors and heaters.

Featuring a control voltage range from 4V to 32V, the relay supports variably controlled inputs to interface flexibly with various control systems. Its silicon-controlled rectifier (SCR) output type delivers instantaneous switching with a turn-on and turn-off time of approximately 0.5 cycles, enhancing system response and productivity.

Built to withstand harsh operating environments, the HD48 operates reliably within a temperature range of -40°C to +80°C, making it suitable for industrial, manufacturing, and HVAC applications. The device’s compact dimensions (45.7mm length, 22.6mm width, 23mm height) allow it to fit in dense panel designs without adding bulk.

The relay's construction includes IP20-rated protection and screw terminal connections with anti-rotation barriers ensuring durable and secure connection stability, diminishing risks of accidental loosening in vibration-prone environments. An off-state leakage current of only 1mA further makes it a power-efficient choice.

Certified to CSA, RoHS, and UR standards, the HD48 resonates with industrial safety and environmental compliance requirements. Commonly deployed in heating control, motor control, and industrial automation systems, this solid state relay improves the longevity and reliability compared to electromechanical relays by eliminating moving parts and offering rapid switching.

Supports maximum load voltage of 530V AC for heavy-duty applications. Control voltage ranges from 4V minimum to 32V maximum for flexible interfacing. Compact dimensions ensure minimal setup space and easy panel mounting.

Operates reliably across a wide temperature range of -40°C to 80°C. Equipped with screw terminals for secure electrical connections. Instantaneous switching function improves operational efficiency. Low off-state leakage current of 1mA reduces power losses.

SCR output type provides fast and variable control of loads. IP20 rated enclosure for protection in standard industrial environments. Conforms to CSA, RoHS, and UR safety and environmental standards.

This Crydom HD48 Solid State Relay is ideal for use in industrial automation, HVAC control systems, manufacturing equipment, and other applications requiring fast, reliable high current switching. Browse EnvMart for additional industrial electrical control solutions and relays from leading brands.
