Industrial Automation & Switchgear sourcing guide
Global B2B Sourcing of Industrial Automation & Low/Medium Voltage Switchgear
Smart manufacturing, power distribution, process control, and facility infrastructure require reliable industrial automation hardware, precise motor controls, and low/medium voltage switchgear that meets specific industry standards. BIGEXPORT connects global industrial buyers with automation component manufacturers and panel builders.
This category is part of Electrical & Electronics. Related sourcing area: Cables & Cable Assemblies and Machinery & Industrial Equipment.
Buyers can submit Requests for Quotations (RFQs) for programmable logic controllers (PLCs), human-machine interfaces (HMIs), air circuit breakers (ACBs), molded case circuit breakers (MCCBs), contactors, variable frequency drives (VFDs), and modular enclosures.

Meeting International Standards for Automation & Switchgear
Buyers can specify compliance with international electrical safety, short-circuit protection, and industrial communication standards in their RFQs. Important standards and capabilities you can request from suppliers include:
Compliance with global standards (IEC 60947, IEC 61439, CE, UL 508A, RoHS, CCC).
Comprehensive factory testing including dielectric withstand, short-time withstand current (Icw), and thermal endurance.
Support for multi-protocol industrial communication (PROFINET, Modbus TCP, EtherNet/IP, CANopen) and OEM custom panel integration.
Frequently Asked Questions (FAQ)
Are international safety certificates provided with switchgear and PLC components?
When submitting your RFQ, you can specify that suppliers must provide relevant documentation such as CE, UL, or IEC test certificates, which you can then review along with their technical datasheets and wiring schematics.
What is the difference between an Air Circuit Breaker (ACB) and a Molded Case Circuit Breaker (MCCB)?
ACBs are designed for high-current main distribution systems (typically 630A to 6300A) with adjustable electronic trip units, whereas MCCBs are compact breakers used for medium-range currents (up to 1600A) in sub-distribution panels.
Can manufacturers supply pre-assembled or custom-designed PLC control cabinets?
Yes, you can connect with panel builders who offer turnkey control cabinet assembly. You can specify your requirements, including wiring, labelling, programming support, and factory acceptance testing (FAT), in your RFQ.
