HS3C6NV050D024 Lovato SOLID STATE RELAY 3P 50A W/O HEAT SINK

Why Choose the Lovato HS3C6NV050D024 Solid State Relay?

The Lovato HS3C6NV050D024 is a high-performance three-phase solid state relay (SSR) designed for reliable, contactless switching of industrial AC loads. As part of the Lovato HS3C solid state relay series, it controls all three phases using semiconductor switching technology, providing fast and dependable operation without the mechanical contacts found in conventional electromechanical contactors.

This relay uses SCR (silicon controlled rectifier) outputs with zero-crossing switching, helping reduce electrical disturbances when switching compatible AC loads. Its 4–32 V DC control input enables straightforward connection to PLC outputs, industrial controllers and other low-voltage DC control circuits, while the load side operates across a broad 48–600 V AC range.

With a rated operating current of 50 A AC-51 at 40°C for resistive loads and 15 A AC-53 at 40°C for motor loads, the HS3C6NV050D024 is suitable for demanding three-phase switching applications. This version is supplied without a heatsink, allowing the appropriate thermal management solution to be selected for the installation and operating conditions.

Reliable Contactless Switching for Three-Phase Loads

Solid state relays such as the Lovato HS3C6NV050D024 switch electrical loads electronically rather than using moving mechanical contacts. The absence of mechanical switching contacts eliminates contact bounce and mechanical contact wear, making solid state technology particularly suitable for applications involving frequent switching cycles and automated process control.

The HS3C6NV050D024 combines three SCR-controlled outputs with zero-crossing operation, allowing all three phases of a compatible AC load to be switched from a 4–32 V DC control signal. Its broad 48–600 V AC operating range and high electrical isolation make it well suited to industrial heating, machinery and automation systems. Appropriate heatsinking and thermal design should be provided according to the load current, ambient temperature and installation conditions.

Typical Applications

• Three-phase industrial heating systems.
• Resistive heaters and heating elements.
• Industrial ovens, furnaces and drying equipment.
• Packaging and production machinery.
• Process temperature-control systems.
• Industrial automation and PLC-controlled equipment.
• Three-phase motor switching within the applicable AC-53 rating.
• Applications requiring frequent contactless switching of AC loads.
