Carlo Gavazzi Three-Phase AC Solid State Relay Panel Mount 25 A Load 660 V Load 50 V DC 275 V AC Control RZ3A

The Carlo Gavazzi RZ3A60A25 is a three-phase AC solid state relay designed for panel mounting in industrial and automation environments. It supports a maximum load current of 25 A and a maximum load voltage of 660 V, making it suitable for switching medium-power AC loads with precision and reliability.

This solid state relay features a zero cross switching function which minimizes electrical noise and extends load and relay lifespan. It operates with a thyristor output type, providing efficient and silent operation without mechanical wear.

The relay accepts control voltages of 50 V DC or 275 V AC, offering flexibility in control circuit design. Screw terminals facilitate robust and user-friendly installation. An integrated mains filter suppresses electromagnetic disturbances, promoting stable operation within diverse electrical environments.

Equipped with an LED indicator, the device allows quick verification of control voltage presence, improving troubleshooting and maintenance efficiency. The relay's IP10 rating offers protection against intrusion of solid objects, supporting safe operation in industrial panel assemblies.

Designed to operate reliably over temperatures ranging from -30°C to 80°C, it is engineered for demanding industrial, laboratory, manufacturing, HVAC, and automation applications. The compact dimensions (103 mm length x 73.5 mm width x 41 mm height) enable convenient integration into control panels and equipment.

Zero cross switching reduces electrical noise and improves relay life. Screw terminal type ensures secure and convenient wiring. Thyristor output provides reliable switching performance. 50 V DC and 275 V AC control voltages support versatile control schemes.

Frequency operation range of 45 to 65 Hz suits standard industrial power systems. Low off-state leakage current of 3 mA minimizes power dissipation when off. Integrated mains filter reduces electromagnetic interference for stable operation.

LED indicator offers visual confirmation of control voltage application. Wide operating temperature range (-30°C to 80°C) allows use in harsh environments. Compact panel mount design fits standard industrial enclosures.

This relay series by Carlo Gavazzi is suitable for use in electrical automation, manufacturing control systems, HVAC switching, industrial machinery, and energy management systems. It complies with EAC and CE standards and is manufactured in Malta to ensure quality and durability.
