VIB-24 Indoor High Voltage Vacuum Circuit Breaker is a new generation vacuum circuit breaker for Shaanxi Shaankai-Longxiang Electrical Ltd. It is independently designed and developed by our-selves on the basic of absorbing the merit of same type for the products at home and abroad. The Product conforms to national standard GB1984-2003 <>, JB3855-1996 <<3.6~40.5kV Indoor AC HV Vacuum Circuit Breaker>>, DL/T403-2000<> and some stipulation of IEC, the capability reach requirement of M2-E2-C2 grade.
VIB-24 Indoor High Voltage Vacuum Circuit Breaker adopt the incorporate design with operating mechanism and reality of VCB, it can be used for fixed installation unit and also can be used for withdrawable by equipped with mainstream Switchgear.

ZN23-40.5C series indoor high voltage vacuum circuit breaker is used for many kinds of switchgears like JYN1-35 and GBC-35 etc. It is widely used for 40.5kV voltage systems which is accordance with GB1984-2003 standards. This series of VCB include: Vacuum circuit breaker truck, isolating truck and PT truck.

ZN39-40.5 type indoor HV vacuum breaker is used for many kinds of switchgear like JYN1-35 and GBC-35. It is widely used for 40.5kV voltage systems which is accordance with GB1984-2003 standards.
This series include: Vacuum circuit breaker truck, isolation truck and fuse truck.

Structural characteristics:
1. This vacuum circuit breaker adopts compound insulation; it can meet air distance and creepage under normal run condition, and it effectively reduces the dimension of VCB, the overall arrangement is reasonable and simple, with aesthetic appearance.
2. The operating mechanism is adopted CD10II electro-magnetic operating mechanism or CT19N spring operating mechanism, the outlet curve has good adaptation with requirements of vacuum interrupters. It has high reliable with characteristics of long life and easy maintenance.
3. Easy pushing-in or pushing-out of panel for the truck; compulsive mechanical interlock way is adopted; meet the “Five Preventions” function; suitable for varies site and the working sites which have rigorous run condition.

NS series moulded case circuit breaker is one of the most advanced type breakers in the world,which adopt international advanced design and manufacture technolgy. They are suitable for shortcircuit and overload protection for circuit of AC 690V 50/60HZ, rated current from 12.5A to 630A. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting
overload, short circuit and lacking voltage.

Product Name: Miniature Circuit Breaker
Model Number: DZ47-63
Place of Origin: China
The breaker is suitable to be applied in the power distribution system for illumination (corresponding to model C) and motor (corresponding to model D). The circuit breaker is characterized by elegant appearance, small volume, light weight, excellent and reliable performance, high breaking capacity, instantaneous tripping, guide rail installation, case and components are made of high fire-retardant and shockproof plastic, as well as long service life properties. It mainly functions as overload and short-circuit protection in the line of single-pole of 230V and 2-, 3-, or 4-pole of 400V, when current is up to 63A. Also, it is used for infrequent making and breaking electrical apparatus and lighting circuit under normal conditions.
