MNS low-voltage switch cabinet is out of a standard module from the modular factory-assembled low-voltage switchgear, the device for 50 ~ 60Hz, rated working voltage 660V and below the power supply system for power generation, transmission and distribution , power conversion and control of energy consuming equipment. The device in line with national standards IEC439 and GB7251.1-1997 "Low-voltage switchgear and control equipment" and other related standards.
■ Type Switchgear □ cabinet power distribution center (PC) The use of ME, F, M, AH Series, such as circuit breakers. □ Motor Control Center cabinet (MCC) Assembled from a drawer the size of the circuit using the main switch or Molded Case Circuit Breaker High Breaking rotary switch with fuses of the load. □ cabinet power factor automatic compensation
■ Features □ Compact design: The small space can accommodate more functional unit. □ unified structure, assembly and flexible: to 25mm for the modulus of the C-profiles can meet a variety of structural types, grades and the use of environment protection requirements. □ the use of standard modular design: each of the composition of the protection, operation, conversion, control, regulation, determination, direction, such as standard cell, the user can choose according to the needs of any assembly. Assembly of more than 200 pieces can be composed of different options Shelves structure and drawer units. □ Security: a large number of high-strength flame-retardant engineering plastics components, effective to enhance the performance of protective security. □ high technical performance: The main parameters to achieve the level of contemporary international technology. □ compression sites: three high degree of compression can greatly prefabricated parts storage and transportation venues. □ easy assembly: No special complicated tools.
■ Degree of protection
□ comply with IEC529, DIN40050 standard □ IP30 protection to more than solid Φ2.5mm □ IP40 protection to more than solid Φ1.0mm □ IP54 against dust and splash in any direction for the protection (IP54 protection level should be ordered with factory consultations) ■ Basic parameters
