Product Description
CJMlM8 Series circuit Breaker, is the company's comprehensive use of international advanced technology design and development and obtained a number of patents of new products, with small compact, modular, high break, double breakpoints, 0 of flying arc, green environmental protection and other characteristics. Suitable for AC 50Hz, 60Hz, rated operating voltage 690V and below, rated current 12.5A to 1600A distribution network, used to distribute electrical energy and protection lines and power supply equipment from overload, short circuit and undervoltage failure hazards. lt can also be used as anon-frequent conversion of the line under normal conditions and in the infrequent start of the motor.
CJMM8 circuit breaker equips with intelligent controller as well, which not only makes its current adjustable but also grants protection against overload(long delay), short-circuit(short delay), short.circuit(instantaneous) & undervoltage. it'll certainly improve the entire power system's reliability, continuity& security. RS485 interface,MODBUS-RTU protocol.With MODBUS modul equipped,customers canchoose options as below. Remote signal: Switching ON/OFF, tripping, alarm & malfunctional singalindication.
Remote control: Switching ON/OFF,reset.Remote test: 3-phase cuttent & N-pole current, grounding current.Remote adiustment: accept and execute remote command to debug remote control. Tripping unit menory recording function, last three time'tripping records can be well traced.
CJMM8 circuit breaker complies to GB/T14048.2, 1EC60947-2 standards, with CE certificate approved.
Normal work and installation conditions
1. The altitude of the installation site does not exceed 2000m;
2. The CJMM8 thermomagmetic type with temperature of the surrounding medium is-5 ºC~+40 ºC, and the average temperature of 24h is not more than +35ºC . The relative humidity of the air at the installation site does not exceed 50% at a maximum temperature of +40ºC : at lower temperatures, there may be a higher relative humidity: the average minimum temperature of the wettest month does not exceed+25ºC for the average of the month. The maximum relative humidity is not more than 90%, and the condensation on the surface of the product due to temperature changes is considered.
3. CJMM8 intellgent type with temperature of the surrounding medium is -40 ºC~ +80 ºC.
4. The product is used in non-explosive hazardous media, and the media does not have enough tocorrode metals and destroy insulating gases and conductive dust.
5. In places where there is rain protection and no water vapor.
6. The installation category is Class lIl.
7. The pollution level is level 3.
8. The basic installation of the circuit breaker is vertical (ie vertical) or horizontal (ie horizontal).
9. The incoming line is either the up line or the down line.
10. Circuit breakers can be divided into fixed and plug-in types.
