Crydom Industrial 75A 530V AC Panel Mount Solid State Relay, 32V Control HD4875

Crydom HD4875 Solid State Relay is a high-performance industrial electronic component designed for controlling heavy electrical loads with up to 75 amperes at a maximum of 530 volts AC. Manufactured for panel mounting, it supports applications requiring high reliability and durability in automation, HVAC, and food production industries.

Featuring a low input control current of 12mA, this relay offers energy-efficient operation and reduces control power consumption. The device includes anti-rotation barriers and secure screw terminals, which help prevent disruption from mechanical vibration and ensure consistent electrical connections.

A zero-cross switching function provides smooth and noise-free switching by activating the load when the AC waveform crosses zero volts, enhancing the longevity of connected equipment. The solid-state construction, with a direct-bond copper substrate, improves heat dissipation to maintain stable operation under demanding load cycles.

Compactly sized at 58.4mm length, 23mm height, and 22.6mm width, the relay easily integrates into existing control panels without occupying excessive space. Its robust aluminum base plate grants resistance to corrosion and mechanical impact, well suited for industrial and commercial environments.

Supports heavy electrical loads up to 75A with 530V AC maximum load voltage. Panel mount configuration allows straightforward installation in industrial control systems. Low control input current of 12mA delivers energy efficiency.

Strong aluminum base protects the relay from corrosion and impact. Zero-cross switching minimizes electrical noise and mechanical wear. Wide operating temperature range from -40°C to 80°C for harsh environments. Screw terminals ensure secure, vibration-resistant electrical connections.

Certified to CSA, RoHS, and UL standards for safety and compliance.

This Solid State Relay is an ideal choice for industrial automation, manufacturing equipment, HVAC systems, and food processing lines requiring fast, reliable switching without mechanical wear. Its durability and compact size make it suitable for crowded panels prevalent in modern electrical installations.
