Solid State Relay 1NO 30A 230VAC

Type 77.31 Industrial Solid State Relays (SSR) are particularly suitable for resistive loads and for industrial applications where high switching frequencies and high inrush currents can be problematic.

Modular solid state relays, 1NO 30 A output, Zero-crossing switching, designed for the following applications:
• Lamp inrush current reduction (CFL – Compact Fluorescent energy-saving Lamps and similar)
• Heater control
• Solenoids, contactor coils

• 17.5 mm housing
• 60 to 440 V AC output (with double SCR)
• 6 kV (1.2/50 μs) insulation between input and output
• High switching speed and long electrical life
• Silent switching, without electric arc and rebounds
• Low absorption input circuit
• Position of relay version terminals (terminals entrance and exit on opposite sides)
• Also suitable for three-phase systems
• 35 mm rail (EN 60715) mounting
