SSR Relays, Solid State Relays and Contactors for Industrial Automation
Looking for an SSR relay, solid state relay, contactor or industrial relay for an electric heater, motor, pump, electrical panel or industrial machine? RezistenteMag.ro offers components for switching and automating electrical loads.
The range includes single-phase and three-phase SSR relays, contactors, interface relays and industrial relays from brands including ENDA, FOTEK, OMRON, HIMEL, ABB and Schneider Electric.
Solid State Relays for Industrial Applications
An SSR - Solid State Relay - is used to switch an electrical load through an electrical control signal.
In electric heating applications, SSR relays are commonly installed between the temperature controller and the electric heater.
Temperature Sensor → PID Controller → SSR Relay → Electric Heater
SSR Relays for Electric Heaters
Electric heating control is one of the most common applications for solid state relays.
SSR relays can be used with:
- cartridge heaters;
- band heaters;
- ceramic heaters;
- tubular heaters;
- air heaters;
- immersion heaters;
- industrial ovens;
- heated moulds;
- Hot Runner systems;
- extrusion and injection moulding equipment.
25A, 40A, 70A, 75A and 100A SSR Relays
Current rating is one of the main parameters to consider when selecting a solid state relay.
The RezistenteMag.ro range includes 25A, 40A, 70A, 75A and 100A SSR relays, depending on model and manufacturer.
SSR selection should not be based only on the current value printed on the device. Actual load current, ambient temperature, switching frequency and cooling conditions should also be considered.
AC and DC Input SSR Relays
The SSR control voltage must be compatible with the output of the temperature controller, PLC or automation system.
Different input configurations are available, including DC, AC and AC/DC control, depending on the selected model.
Single-Phase and Three-Phase SSR Relays
Single-phase SSR relays are available for single-phase electrical loads, while three-phase solid state relays can be used in systems where three phases need to be controlled.
The range includes three-phase models such as 3x25A and 3x40A SSR relays for industrial electrical heating and automation applications.
ENDA SSR Relays
ENDA offers solid state relays with different control voltages, current ratings and load configurations.
Available models include:
- ENDA EPAA1-225Z - 25A;
- ENDA EPAA1-240Z - 40A;
- ENDA EPAA1-470Z - 70A;
- ENDA EPDA1-240Z - 40A;
- ENDA EPDA1-470Z - 70A;
- ENDA EPDA1-4100Z - 100A;
- ENDA EPDA3-425Z - 3x25A;
- ENDA EPDA3-440Z - 3x40A.
FOTEK and OMRON Solid State Relays
The category also includes FOTEK and OMRON SSR relays for industrial switching and automation applications.
Depending on model specifications, these products can be used for electric heaters and other compatible electrical loads.
Industrial Contactors for Motors and Electrical Loads
For applications requiring electromechanical switching, the category also includes industrial contactors.
HIMEL and ABB contactors are available in different current ratings for three-phase applications.
Contactors are commonly used in electrical panels for motors, pumps, heaters and other electrical loads.
Interface Relays and Industrial Relays
Interface relays can be used to transfer and isolate control signals between different circuits and components inside an electrical panel.
The category also includes Schneider Electric interface relay solutions together with other industrial control components.
Where Are SSR Relays and Contactors Used?
- electrical control panels;
- electric heaters;
- PID temperature control systems;
- industrial ovens;
- plastic injection moulding machines;
- extrusion lines;
- heated moulds;
- Hot Runner systems;
- electric motors;
- pumps;
- packaging machines;
- production lines;
- HVAC systems;
- industrial automation.
How to Choose an SSR Relay
Correct SSR selection requires knowing the electrical characteristics of the control system and the connected load.
Check:
- control signal voltage;
- load voltage;
- load current;
- single-phase or three-phase system;
- electrical load type;
- electrical panel temperature;
- cooling or heatsink requirements;
- switching frequency.
Not Sure Which SSR Relay or Contactor You Need?
If you are replacing an existing component, send us the model number or a clear photo of its label.
For a new application, tell us the voltage, power, current, number of phases and the equipment you want to control.
For electric heating systems we can also evaluate the complete configuration: electric heater + sensor + PID controller + SSR relay.
