Schneider Electric – Control and automation technology for industrial applications

Schneider Electric

Schneider Electric is a globally active manufacturer of solutions for energy management and automation technology. The company develops electrical control, switching and monitoring components used in industrial plants, machinery, infrastructure systems and mobile applications. The focus is on the safe, reliable and efficient control of electrical processes across many industries.

Schneider Electric products are used wherever electrical energy must be switched, distributed or monitored – whether in stationary industrial installations, machine control systems or mobile systems.

Schneider Electric control and switching components

Schneider Electric’s portfolio includes several established product lines that have been considered industry standards for many years and are used in a wide range of applications. These include, among others:

  • TeSys – contactors, motor protection circuit breakers and motor starters for switching and protecting electric drives
  • Harmony – pushbuttons, selector switches and signalling devices for operating and control functions on machines and systems
  • Modicon – PLC controllers and automation systems for complex control and regulation tasks
  • Zelio – compact relay and logic modules for simple control functions

These product families cover key functions in industrial control and automation technology and are designed for continuous use under demanding environmental and operating conditions.

 

Typical application areas

Schneider Electric control and automation components are used across industries, including machine and plant engineering, conveying and drive systems, power distribution, as well as commercial vehicles and mobile applications. Modular designs and graded performance ranges allow the components to be adapted flexibly to different technical requirements.

Use on lifting and loading systems

In certain applications, Schneider Electric components are also used on lifting and loading systems, for example on tail gates (lift gates) or comparable installations. In this environment they perform switching, control or monitoring functions within the electrical system. A prerequisite is always that the respective component meets the technical, electrical and safety-related requirements of the system.

Not every product line is intended for this use; the specific version and system compatibility are always decisive.

Spare parts, maintenance and servicing

Schneider Electric control and switching components are used both in new system construction and as part of maintenance, repair and servicing. As spare parts, they help restore the function of electrical systems and secure it over the long term.

For workshops and service operations, selecting technically suitable components is crucial to avoid downtime and to ensure long-term operational safety of machines and systems.

Schneider Electric – frequently asked questions (FAQ)

Which details do I need to reliably identify a Schneider Electric component?

Typically helpful: the part/type number, product range (e.g. TeSys/Harmony/Modicon/Zelio), voltage range, contact/circuit diagram, configuration (e.g. 1NO/1NC), connection type and installation dimensions. What matters is the technical match with the existing control system.

How can I tell whether a contactor/relay/pushbutton is compatible as a replacement?

Key points are electrical data (coil/supply, current/switching capacity), contact configuration, protection rating, mounting/terminal layout and how it is integrated into the system. If specifications and connections match, replacement is often possible.

Which typical symptoms indicate a fault in switching or control components?

Common signs include intermittent failures, “clicking” without switching, contact issues (heated/burnt contacts), unreliable enable signals, malfunctions during start/stop or messages in the control unit. Causes can include wear, moisture, corrosion or overload.
