Circuit breakers
Miniature, moulded-case and selected industrial breakers. Current rating, breaking capacity, poles, trip curve and mounting must be confirmed.
Product group 03 · Control & protection
Electrical and automation components for industrial control and protection.
Electrical components are only comparable when the rating, mounting, connection and approval requirements are clear. Send the device type, technical data and quantity; we will help identify suitable supply options.
Overview
Product overview.
We do not claim certifications, voltage ratings or approvals that have not been verified for the actual product. Compliance documents are confirmed per supplier and per order.
This page explains the common product families, the information a supplier needs and the purchasing questions worth resolving before an order. Specifications vary by model and supplier; all technical data is subject to confirmation upon inquiry.
Product scope
10 families- Circuit breakers
- Contactors
- Relays
- Switches
- Electrical connectors

Ratings, breaking capacity, coil voltage, mounting standard and approvals must be confirmed against the actual datasheet. We do not substitute unverified devices for safety-critical applications.
Product families
Common types and what distinguishes them.
Contactors & relays
Motor switching, control and interlock devices. Coil voltage, contact configuration, duty and auxiliary modules are part of the specification.
Switches & sensors
Limit, proximity, pressure, level and selected process sensors. Sensing range, output, supply, housing and connection must match the application.
Connectors & terminals
Industrial plugs, sockets, terminal blocks and wiring accessories. Pole count, current, voltage, conductor size and IP rating need to be confirmed.
Control components
Pushbuttons, selector switches, indication, timers and selected control accessories for panels and machines.
Automation components
Selected PLC, I/O, drive and interface products where the exact model, compatibility and documentation can be confirmed.
Protection components
Surge, overload, phase and motor protection devices. The applicable standard and coordination requirements must be verified for the project.
Specifications vary by model and supplier; all technical data is subject to confirmation upon inquiry.
Custom requirements
Standard product not enough?
Available supply options may include standard products and customized specifications, subject to project requirements. Share a drawing, sample or performance requirement and we will review suitable manufacturing and supply options.
Discuss Custom RequirementsMaterials & standards
The details that change the quote.
The ranges below are common industry references, not a statement of stock or supplier capability. The applicable grade, standard and test requirement must be confirmed for the specific inquiry.
- Electrical ratings
- Voltage, current, poles, frequency, breaking capacity and duty. A model number alone may not be enough; confirmation against the datasheet is required.
- Control interface
- Coil voltage, signal type, contact configuration, communication protocol and compatibility with the existing control system.
- Mounting and connection
- DIN rail, panel cut-out, terminal type, conductor size and wiring space. These determine whether a device can be installed as intended.
- Environment
- Ambient temperature, enclosure, IP rating, vibration and corrosive atmosphere. Confirm the actual product rating before selection.
- Documentation
- Datasheets, declarations and test documents can be requested where available. Certifications are not claimed unless verified for the specific product.
- Lifecycle and replacement
- For obsolete controls, a form-fit-function replacement may need sample verification and engineering approval before use.

Before you buy
Purchasing considerations.
Verify the actual rating
Do not rely on a generic product photo. Confirm voltage, current, breaking capacity and approvals on the datasheet for the exact model.
Check system compatibility
Coil voltage, signal type, communication and mounting must match the existing panel and control system.
Keep safety responsibility explicit
Safety-critical selection, coordination and approval remain the buyer’s engineering responsibility unless a separate engineering scope is agreed.
Plan for documentation
State the required datasheets, declarations or test records in the inquiry. Not every supplier provides the same package.

FAQs
Common questions about electrical & automation.
Can you supply a specific brand or model?
We can check availability for a specified model or propose alternatives where appropriate. Brand, model and approval requirements should be stated in the inquiry.
Do you guarantee certifications or approvals?
No. Certifications are confirmed for the actual product and supplier. We do not claim a certification, voltage rating or approval that has not been verified.
Can you help with obsolete control components?
We can look for the original item or a compatible alternative. Form, fit, function and safety implications should be verified before installation.
What information is needed for a quotation?
Provide the device type, model or datasheet, ratings, quantity, required documentation and destination. Photos of the existing panel can help identify the context.
Can you supply complete control panels?
Selected panel and assembly requirements can be discussed, but engineering responsibility, drawings, standards and testing scope must be defined before quotation.
