Recycled Materials MCB Circuit Breaker Modular Vacuum Tandem , Fixed Installation

400A 4P Moulded Case Circuit Breaker Thermal Switch Mccb

Usage and scope of application

The design of CNSV series of MCCB reflects the latest current limiting principle and manufacturing technology, characterized by compact structure, full modularization, high breaking, and zero arcover. Its rated insulation voltage is 690V, rated operating voltage is AC50/60Hz, 440V and below, rated current up to 630A. It's used for generating infrequent conversion and infrequent startup of the motor. Circuit breaker is equipped with overload, short circuit and under voltage protection devices, so as to protect the circuit and E type compact power equipments from damage.

The materials used do not pollute the environment

No pollution of production equipment, conforming to ISO 14001 standard

Recycled materials can be recycled

The power consumption per pole is very low and can be ignored

High quality flame-retardant enclosure, high protection level, simple and convenient combination structure.

Process characteristics and properties

1. the frame of the box body is made of ten percent off profiles, and the high-quality and special three links are welded together into a whole. The structure is solid and reliable, and the appearance is graceful.

2. the lower edge of the door plank is about 25mm away from the ground, and the rectangular frame fixed on the door panel is provided with a circular hole every 25mm, so as to not only enhance the strength of the door panel. It can also be used to install electrical wiring harness, electrical appliances and other components.

3. the top cover, side plate, back slope and bottom plate are all screwdriver fasteners fixed, easy to assemble and disassemble, and the installation work inside the cabinet is more convenient.
