Solid State Relays

Solid State Relay for Industrial Switching Without Mechanical Wear

A solid state relay (SSR) is an electronic switching device that uses semiconductors instead of mechanical contacts. It enables silent, vibration-resistant switching with no arc formation — ideal for automation panels, HVAC systems, and industrial heating loads.

Unlike electromechanical relays, solid-state relays offer fast response, high reliability, and extended life cycles even under heavy-duty loads. We stock SSRs rated for DC, AC, and three-phase applications.

DC Solid State Relay Options — Switching Without Spark

For applications involving PLC outputs, sensors, or DC-powered actuators, a dc solid state relay provides clean isolation and fast switching — often in the 5–48V or 24VDC range.

We offer:

• Finder SSRs – compact DC/DC units with DIN-rail clip housing
   
• Phoenix Contact – DC relay modules with integrated diagnostics
   
• Schneider Electric Harmony series – robust for repetitive start/stop commands
   
• Siemens Sirius 3RF – designed for high switching frequency in automation
   
• Eaton SSR-DC – rugged SSRs for control panel integration
   
• Weidmüller TERMSERIES – plug-in relays with transparent housing for visual control
   

Common voltages: 5V / 12V / 24V / 48V input, switching up to 100VDC or more depending on model.

Three-Phase Solid-State Relay – Industrial Heating and Motor Load Control

A 3 phase solid state relay is used in ovens, HVAC units, motor starters, or industrial lighting — anywhere high current must be controlled with electrical precision and minimal EMI.

Key specs to consider:

• Switching current: up to 75A, 100A, 125A or more per phase
   
• Voltage: up to 600VAC
   
• Trigger signal: 4–32VDC or universal AC/DC
   
• Mounting: panel-mounted with heat sink or DIN rail clips
   
• Overheat protection: available on premium models from Finder and Phoenix
   

Siemens and Schneider Electric models are widely adopted across EU manufacturing plants for their CE-compliant safety and diagnostic features.
