Enclousers & Breakers
CW1 series intelligent universal circuit breaker (hereinafter referred to as circuit breaker), Apply to 50Hz AC, Rated voltage to 660V (690V) and below, in the distribution network with rated current of 200A ~6300A, circuit break used to distribute electric energy and protect circuit and power equipment from overload, undervoltage, shortcircuit, single-phase grounding and other faults has intelligent protection function. Selective protection is accurate, it can improve the reliability of power supply, avoid unnecessary power failure, and has an open communication interface. It can carryout "four remote" to meet the requirements of the control center and the automation system. The circuit breaker has a pulse withstand voltage of 8000V at an altitude of 2000 meters (the maximum withstand voltage is not more than 12000V according to the standard for different altitudes). The circuit breaker can be used as an isolator without intelligent controller and sensor, and is marked as -*The circuit breaker conforms to GB14048.2 "Low Voltage Switchgear and Control Equipment Low Voltage Circuit Breaker" and EC60947-2 "Low Voltage Switchgear and Control Equipment Circuit Breaker" and other standards. Normal Working and Installation Conditions Ambient air temperature The upper limit value shall not exceed +40 �ºC, the lower limit value shall not be lower than-5 �ºC, and the 24-hour average value shall not exceed +30 C; Note: For working conditions with the lower limit value of-10 C or-25 C, the user should declare it with the company. For working conditions where the upper limit value exceeds + 40T: or the lower limit value is lower than-10 C or-25 C, the user shall negotiate with the company; The altitude of the installation site shall not exceed 2000m. Atmospheric conditions The atmospheric relative humidity shall not exceed 50% when the ambient air is + 40 C, and may have higher relative humidity at lower temperatures. The monthly average maximum relative humidity in the wettest month is 90%, and the average minimum temperature in that month is + 25 �ºC. Considering that the condensation on the product surface due to temperature change exceeds the specified requirements, the company shall be consulted.

NS 250A MCCB mccb circuit breaker is one of breaker which adopts international advanced design, manufacture technology to develop. The rated insulating voltage is 750V, suit-able for AC 50Hz(60Hz),rated working voltage 690V or below, rated working current is 12.5A to1250A of circuit and used in distributing electric energy, and non-frequent breaking in the nor-mal conditions , protecting the current& equipment from overload&under voltage, circuit breaker with rated frame current 400A or below,can be used in mouse cage motor's non-frequent start,breaking during working, protecting motor from overload, short circuit&under voltage,the product conforms to IEC60947-2 standard.
ABE/ABS moulded case circuit breakeris suitable for industrial or commercial power and lighting with AC50/ 60Hz, rated working voltage up to AC600V/DC250V, rated current up to 630A. Its a kind of economical breaker with the characters of stable and reliable function, beautiful appearance, small size and long life. It can be used for conversion of line and infrequent starting motor. It can also be attached to ins all the accessories which have protection function for avoiding loss of voltage, undervoltage. The product can install connection line with front board and back board, it also can equip hand-operating apparatus or motor-operating apparatus to control in a remote distance.
DPX series MCCBs are made by Legrand company.And DPX series Moulded Case Circuit Breaker is one of the most advanced type breakers in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A.Its rated insulation voltage is 690V. It can make and break the nonfrequently circuit in the normal conditions. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. It complies with IEC60947-2.
moulded case circuit breaker with rated insulation voltage 800V, applied in the power system of AC50(60)Hz, rated voltage 690V and below, rated current 1250A and below as the transfer not frequently. The circuit breaker has the protection devices of over load, short circuit and under voltage ,it can protect the circuit and power equipment from broken. The mccb can be sorted to C type (basic),L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity. The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship. The installation can be vertical or level and the standard conforms to IEC60947-2 and GB14048.2
