NOVUS, 8824211070, SSR-4880 Solid State Relay with Heat Sink NDP3-220, 80 A / 480 Vac

Features:

• No electrical noise, sparking, or mechanical wear.
• Triggering requires low power.
• LED status indicator of the trigger signal.
• Metal isolated housing.
• Internal dv/dt protection snubber sized to switch resistive or inductive loads with power factor up to 0.5.
• Zero Crossing: Turns on at zero Volt, turns or at zero Ampere.
• Optical isolation between command and power.

Solid State Relays are electronic devices used to switch resistive or inductive loads and have several advantages over standard relays or electromechanical contactors. Since they have no moving parts, there is no wear or mechanical operating noise. The zero-crossing actuator drastically reduces electrical switching noise. Electrical isolation between input, output, and metal housing simplifies and ensures safer installation and maintenance. Properly installed, they can operate without failure for many years.
