Plastic-Case Circuit Breaker Installed Circuit Breaker

Company profileWeifang Quneng Electric Technology Co., Ltd., established in March 2017, is located at No. 1277 Yudong Road, Dongcheng Street, Linqu County, Weifang City, Shandong Province. It is a new industrial company specializing in electrical and electrical equipment installation engineering, industrial automation engineering, system integration, maintenance, and sales of electronic and electrical equipment.The company has an advanced technical level, and dozens of senior engineers, particularly electricians, and welders. The company has obtained a four-level installation (repair, test) power facility license, construction enterprise qualification certificate, safety production license, high-tech enterprise, multiple credit rating certificates, GGD, GGJ, MNS, PZ, XL type, JP, and other low-voltage power distribution products, and passed the CQC product certification of China Quality Certification Center.The company's main products are high-voltage switchgear: KYN61, KYN28A-12, XGN2-12, HXGN, GKG (KA) mining cabinets, switching stations, etc.; low-voltage switchgear: MNS, GCS, GGD, PZ, XL type, intelligent power distribution unit (JP series), high-frequency DC power supply cabinet; JYDXH series arc suppression and harmonic elimination cabinet; VS1 vacuum circuit breaker, etc.; substation. The products are sold to all regions of the country and are widely used in power grids, petrochemicals, steel, mining, power generation, biological engineering, large-scale construction projects, and other fields.QUNENG - MMCB (molded case circuit breaker) series  The electronic plastic-case circuit breaker has four protection functions: overload long delay, short delay, short instantaneous, and ground fault. Commonly used, the rated current has the following types 15 25 30 40 50 60 75 80 100 125 160 200 225 250 315 350 400 500 630 A. Working Temperature-5 degree to +40 degree  Arc-extinguishing medium Normal arc extinguishing chamberPort Qingdao port, China Install method  1. Fixed type 2. Plug type 3. Pull typePlastic-case circuit breakers are also known as device circuit breakers, all parts are sealed in a plastic shell, auxiliary contacts, Undervoltage release, shunt release, etc., are modular. Because the structure is very compact, the plastic-case circuit breaker can not be repaired. Most of them use manual operation, large capacity can choose electric closing. Due to the application of electronic overcurrent release, plastic-case circuit breakers can also be divided into Class A and Class B. Class B has good three-stage protection characteristics, but due to price factors, the market share of class A products using thermal magnetic release is higher. A plastic-case circuit breaker is the contact, interrupter, release device, and operating mechanism are installed in a plastic shell, generally does not consider maintenance, suitable for the branch protection switch, over current release device has two kinds of thermal magnetic and electronic, general thermomagnetic plastic-case circuit breaker is a non-selective circuit breaker, only overload long delay and short circuit instantaneous two protection methods. The electronic plastic-case circuit breaker has four protection functions: overload long delay, short delay, short instantaneous, and ground fault. Some of the new products of electronic mold-case circuit breakers also have regional selective interlocking functions. Most of the molded case circuit breakers are manually operated, and some have motor operating mechanisms.FAQQ1: Are you a factory or trading company?A1: We are a factory, and we can guarantee our price is first-hand very cheap and competitive.Q2: What is the payment term?A2: We accept T/T 30% deposit and 70% balance payment, the balance should be paid after acceptance before shipment.Q3: Could I have the prices of your products?A3: Welcome.
