Overview

This product is a combined switchgear assembled with modular components. It is suitable for three-phase AC 50~60 Hz power systems with rated voltage up to 660 V and rated current up to 4000 A, including three-phase four-wire and three-phase five-wire systems.As a low-voltage complete distribution device for power distribution, centralized motor control and reactive power compensation, it is widely used in power distribution centers and motor control centers of power plants, substations, petrochemical, metallurgical industries, factories, mines and high-rise buildings.The product complies with national standards GB 7251, VDE 660, IEC 439 and other standards.

Main Features

★ Compact design: More functional units can be installed in a small space.

★ High versatility of structural parts and flexible assembly. The basic frame is assembled with C-shaped steel sections with a modulus of E=25 mm. The structure and withdrawable units can be combined freely to meet system design requirements.

★ The mechanical interlock mechanism of various drawers complies with standard requirements, with three distinct positions: connected, test and disconnected, ensuring safety and reliability.

★ Standard module design: convenient, compact, highly versatile, flexibly assembled, high technical performance and good safety. It can form standard units such as protection, operation, conversion, control, regulation, measurement and indication, which can be assembled freely according to requirements.

★ High-strength flame-retardant engineering plastic components are adopted. The component materials can prevent fault arcs and effectively improve protection and safety performance.
