Detailed Product Description: | MCB SZRB2-125SZRB2-125 series MCB for AC 50 or 60Hz, rated voltage of 400V and single phase 230V, rated current 125A and below the line, buildings and electrical equipment used to short-circuit , overload protection, can also be under normal circumstances, as infrequent line conversion, but also to isolate the switch and as a line-voltage protection and long way off. The product appearance, small size, light weight, power trip setting precise, reliable action, high breaking capacity, tripping quickly, rail, combined mode design with auxiliary contacts, alarm indication contacts, undervoltage release , shunt trip accessory combination, to meet the needs of different users, the housing and components of high fire-retardant and impact-resistant plastic, long service life. This product complies with IEC60947-2 and GB14048.2 standards. Category 1, the low-voltage switch cabinet 2, 3 AC low voltage distribution cabinet, metal armored away switch cabinet 4 low voltage switchgear fixed-separated 5, high-voltage capacitor cabinet 6, the operation of high voltage switchgear low voltage switch cabinet security technology Practice 1 on all or part of the disc live work, equipment maintenance and operation of equipment should be separated in order to clearly marked. 2, there should be a permanent secondary winding current and voltage transformers, reliable protective earth. 3, in the run of the current transformer secondary loop work low voltage, take the following safety measures: 3.1 non-current loop is disconnected. High Voltage Switchgear 3.2 In order to reliably short circuit current transformer secondary winding, you must use the shorting bar and short routes, prohibit the use of wire is wound. 3.3 prohibit any work on the current transformer circuit and short circuit between the terminals and wires. 4, the operation of the voltage transformer secondary loop work, should take the following safety measures: 4.1 strictly prevent a short circuit or grounding. 4.2 Use insulated tools, wear insulated gloves, if necessary, before the work to stop using protection devices. 4.3 take temporary load low voltage switch cabinet, it must be equipped with dedicated switches and fuses. 4.4 secondary circuit current test in order to prevent an anti-PSA from the secondary side low voltage switch cabinet role, in addition to the secondary circuit breaks, it should also be removed once the fuse. 4.5 secondary circuit is powered on or before the pressure test, the officer shall notify the attendant and low voltage switch cabinet prices, and sent to guard the site, check the circuit before pressing confirm no job. Staff 4.6 Check power protection and secondary circuit, without the permission duty, are not allowed to make any switching operation. Low voltage switch cabinet model, learning Connaught Electrical and Mechanical (online consultation), low voltage is provided by habit Connaught Mechanical and Electrical Equipment Co., Ltd., Henan. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
