The Shanghai People RMK AC contactor, contactor production experience of 50 years, the long-term consistent aim is to provide the market with products of high quality, reliable performance and better service to users of the information released by DDB Electric Co., Ltd., intends to call : Tang: 18324299998 Tel :0577 -27888998 Fax :0577-27,875,998 QQ: 2.26158 million a Scope and implementation of standards RMK series AC contactor is applicable to the main circuit rated voltage AC 50Hz or 60Hz. Rated voltage up to 660V. Making and breaking the circuit in the power system of the rated current of 500A. And appropriate thermal overload relays motor starter. May occur in order to protect the overload circuit. RMK series AC contactor perform the following standards IEC60947-4-1 low-voltage switchgear and control equipment voltage electromechanical contactors and motor starters "the GB14048.4 two, RMK series AC contactor characteristics RMK Series AC contactor internal structure form and features with the more reasonable, the appearance of a more sophisticated appearance. Sophisticated manufacturing processes to provide a new generation of products to the market, the majority of users with the latest research and development means. 2, the full range of products interrupter device is an enclosed structure. The arc generated by the product in the process off load is carried by the inside of the arc chamber and the effective bearing arc, resulting in the operation of the process without any damage on the adjacent member and wire. 3, the external line part of the full range of products all reasonable envelope protection to ensure the safety of the products run maintenance. 4, the shell material of the full range of products use a special high-performance plastics, to guarantee its performance under the premise of more sophisticated appearance. The full range of products from either the appearance or color combinations are the formation of a strong series features a clear overall sense, to create good conditions to improve product taste for the device user.
