Main features:
The switchgear body is of assembly type structure, and the circuit breaker is of handcart and floor stand model structure;
The switchgear is equipped with a brand new compound insulation VCB, which is of good interchangeability and is convenient for exchange; A leadscrew nut feed mechanism is installed inside the handcart frame, so as to easily move the handcart and prevent the feed mechanism
from being damaged due to mal-operation;
All operation can be done while the cubicle door is closed;
All the interlocking between the main circuit breaker, the handcart and the cubicle door are of mandatory mechanical locking means and can satisfy the requirements of five prevention;
The space of the cable compartment is enough to connect several pieces of cables;
The quick earthing switch is used for grounding and short-circuit;
The protection grade of the enclosure is IP3X , and that will be IP2X when the handcart door is open;
The product accords with the standard of IEC62271-200, IEC60694 (idt GB/T-11022-1999), GB 3906, DL 404 and so on.
