Frequently Asked Questions

Which component families can you combine in one order?
Our component range covers eight families: fuses (links, bases, fuse switches, drop-out cutouts), switches (cam, pushbutton, limit, micro, toggle, changeover), circuit breakers (MCB, RCCB, ELCB, RCD, MCCB, motor protection), instruments (panel meters, kWh meters, current transformers, temperature controllers), magnetic starters, AC contactors, relays (thermal overload and general purpose) and wiring accessories (terminal blocks, DIN rail, cable glands, lugs, wiring ducts). Mixed families ship consolidated in one export order.
Do export components comply with IEC standards?
Yes. Catalogue parameters such as voltage level and frequency are based on China State Grid technical requirements; products for export comply with IEC standards (IEC 60269, IEC 60898, IEC 1008.1/1009.1 and related) or according to the customer's project specification.
What information do you need to quote electrical components?
Product family and model (or an equivalent international reference), rated voltage and current, breaking capacity where applicable, number of poles, coil voltage for contactors and relays, quantity and destination port. We return a priced offer with lead time within 24 hours on working days.
Can components be supplied under our own brand?
Yes. OEM branding is a core part of our supply service — private-label nameplates, packaging and documentation packages are available for bidding agents, panel builders and EPC contractors.
