Ac Sf6 Circuit Breaker
Introduction The LWâ?¡-252/4000-50 self-extinction Ac circuit breaker which is outdoor type finds its universal range of applications for the electrical system with elevation not greater than 2000m, ambient temperature not lower than-30C, dirtiness grade not higher than IV, alternating current 50Hz and the maximum voltage 126kV. It is used for cutting the rated current, malfunction current or switching the circuitry, to control and protect the electrical system, and it can also be used for connecting with the circuit breaker The gas of the SF6 is employed as the arc-extinguishing medium and the dielectric material. The self-extinction technology and the new-type spring operating mechanism are introduced in the SF6 circuit breaker. Thus the circuit breaker has good qualities with long electrical life, low operation power, lower noise, high reliability, simple structure, small and long overhaul periods. It can fully replace the import same type one. Caracteristic of structure The breaker introduces the three-phase porcelain -pole with single interrupter structure. A spring operating mechanism is supplied and the mechanical action of the three-phase is inner connected. The gas of the SF6 is connected in the three-phase pole parts. A density controller with temperature compensation is used to monitor the gas of the SF6. Because of the self-extinction arc control principle and optimized design, it improves the efficiency of mechanism and reduces the operating power Excellent breaking performance and long electrical life High mechanism reliability and can be operated frequently Because of the high insulation intensity and excellent contact movement, the breaking capacity current will not re-burn The circuit breaker has high outer insulation level and ratio creepage distance is greater than. So it has excellent performance of resisting the filth and the earthquake, it is also can be operated safely under the environment with atrocious weather High carrying ability: it has high capability margin as the temperature of each contact rises when it is under temperature rise test in the circuit (1.2 times 0f 4000A) The appearance of the breaker is compact, and the installation and debugging is very easy. The maintenance is also very convenient

About circuit breakers Trade

circuit breakers is one of the most actively traded commodities in global B2B markets. Major exporting countries include Ukraine, Russia, Argentina, and India, which together account for over 80% of global production. Buyers from the Middle East, Africa, and Southeast Asia represent the largest import demand.

When sourcing circuit breakers, buyers typically evaluate suppliers based on price per metric ton, minimum order quantities, certifications (ISO, HALAL, SGS), and payment terms. The most common payment methods used in circuit breakers trade are Letter of Credit (L/C) and Telegraphic Transfer (T/T).

EximNext connects buyers with 1,240+ verified circuit breakers suppliers across 67 countries. Post a buy requirement to receive competing quotes within 24 hours, or browse our verified supplier directory to compare prices, certifications, and response times.

Search Products on EximNext — Source From Verified Global Suppliers

This is the EximNext product search page — one place to search across our entire B2B catalogue of wholesale and export-ready products. Type any product name, material, grade, or HS-style keyword into the search bar above and instantly browse matching listings from verified manufacturers, suppliers, exporters, and wholesalers in more than 200 countries. Whether you are sourcing raw materials, components, machinery, or finished goods, the search brings the right products and the right factories to one screen so you can compare and shortlist in minutes instead of days.

Search across hundreds of thousands of products and every major category

The catalogue spans the full breadth of international trade: agriculture and farm inputs, food and beverages, apparel and fashion accessories, electronics and electrical goods, industrial machinery and chemicals, construction and real-estate materials, minerals and metals, home furnishing, and a wide miscellaneous range. Each result links to a detailed product page with specifications, minimum order quantity, FOB and CIF pricing signals, certifications, and the supplier's trade profile. Because every category is interconnected, a single search can surface closely related product families — helping importers discover alternatives, substitutes, and adjacent lines they may not have considered.

Filter, compare, and shortlist the right suppliers

Use the side filters to refine results by supplier country, business type (manufacturer, exporter, trading company, distributor), verification status, certifications, price band, and minimum order quantity. Sort by relevance, price, or recency, and switch between list and grid views. Every supplier on EximNext is surfaced with the trust signals that matter for cross-border trade — verification, response rate, and trade history — so you can build a credible shortlist before you ever send an inquiry. When you find a match, request a quote directly or post a buying requirement and let competing suppliers come to you.

Built for bulk buyers, importers, and procurement teams

EximNext is a global B2B marketplace designed for serious sourcing. Buyers searching here are typically comparing factory-direct pricing, checking MOQ against their purchasing plan, and evaluating certification depth and export experience into their destination market. The platform standardises how suppliers present their capabilities, so you can compare like with like and negotiate from an informed position. For first-time importers this transparency removes much of the guesswork that usually slows a deal; for experienced buyers it powers faster, tighter sourcing cycles across many products at once.

Why search and source on EximNext

Traditional sourcing means scattered trade shows, unanswered emails, and unverified contacts. EximNext replaces that with a single searchable marketplace where verified manufacturers, suppliers, and exporters compete for your order. Search any product, filter to your exact requirement, compare suppliers side by side, and request quotes — with no sourcing agents and no middlemen. Explore the full directory by browsing all product categories, or post a buying requirement to receive competitive quotes from verified suppliers within hours. EximNext gives global buyers and sellers one trusted place to trade smarter, source faster, and grow across international markets.

How product search works on EximNext

Start with a broad term and narrow down as you go. A search for a generic product such as “rice”, “steel pipes”, or “LED lights” returns every matching listing ranked by supplier trust, verification, and recency; from there you can tighten the result set with the side filters, switch sort order, or add a more specific term like grade, variety, or packaging. Suppliers across more than two hundred countries list their products with detailed specifications, so the same search surfaces factory-direct manufacturers, established exporters, and specialist trading companies side by side. Because EximNext indexes products across every major industry — agriculture, food and beverages, apparel, electronics, industrial machinery, chemicals, construction materials, minerals and metals, and home goods — buyers can run their entire sourcing programme from a single search bar. Every result is one click from a full product page, a verified supplier profile, and a request-for-quote form, turning a casual search into a qualified inquiry in minutes. Save time, compare confidently, and source directly from the manufacturers and exporters who can actually fulfil your order.
