PRODUCTS

NDM2ZB Series DC Three-segment Molded Case Circuit Breaker

Nader NDM2Z series MCCB is applicable to DC power grid circuits with rated working voltage of DC250V and rated working current of 10A to 800A, and are used to isolate, distribute electric energy, protect circuits and power supply equipment. The circuit breaker has overload and short circuit (NDM2ZB also has short circuit short delay protection).

NDM2E Series Electronic Molded Case Circuit Breaker

NDM2E series MCCB is mainly used for infrequent switching in circuits with AC 50Hz, rated working voltage AC400V and rated working current 40A to 800A. It has the functions of isolation, overload long time delay inverse time limit, short-circuit short time delay inverse time limit, short-circuit short time delay fixed time limit, short-circuit instantaneous, grounding fault protection, current imbalance protection, phase failure protection, "four remote" function, overload alarm non tripping and undervoltage protection, and can protect the line and power supply equipment from damage. This product complies with the standards IEC 60947-2 and GB/T14048.2.

NDQ Series Automatic Transfer Switching Equipment

Nader NDQ1 series (63A-800A) ATS (CB level) is applicable to AC rated working voltage of 63A~225A shell frame 400V and below 400-800 shell frame 415V below, automatic conversion between two power supplies in the emergency power supply system with rated frequency of 50Hz and rated current of 16A to 800A to ensure continuous, safe and reliable operation of important loads (such as fire load). It is widely used in hospitals, shopping malls, banks, chemical industry, high-rise buildings, military facilities, fire fighting and other important places where power failure is not allowed.

NDB5 Series Hydraulic Electromagnetic Circuit Breaker

Nader NDB5 series HMCB is suitable for rated current of 0.5A to 63A, and multi pole parallel connection to 150A. In the power system with rated voltage of AC230 to AC480V, 50Hz / 60Hz, DC80V and below, it can be used for overload and short-circuit protection, and also for infrequent connection and disconnection. It can be widely used in computer and its peripheral equipment, industrial automatic control system, telecommunication equipment, general power supply system, UPS uninterruptible power supply equipment, railway locomotive, marine electrical system, aerospace, elevator control system and mobile power supply equipment.

NDB3 Series Hydraulic Electromagnetic Circuit Breaker

Nader NDB3-30, NDB3-50 and NDB3-100 series HMCB is applicable to power systems with rated current up to 100A, rated voltage of AC480V, AC277V, 50Hz / 60Hz and DC125V and below. The products can be used for overload and short circuit protection, and can also be used for infrequent connection and disconnection. It is widely used in computer and its peripheral equipment, industrial automation system, telecommunication equipment, general power supply system, UPS uninterruptible power supply equipment, railway locomotive, marine electrical system, aerospace, elevator control system and mobile power supply equipment

NDB6-125 Series Circuit Breaker

Nader NDB6-125 series MCB is applicable to power lines with AC 50Hz / 60Hz, rated voltage AC230V to AC415V, DC60V to DC125V, and rated current 63A to 125A. They can be used for overload and short-circuit protection of power facilities and electrical equipment, as well as for infrequent switching of lines and infrequent starting of motors, and as disconnectors. This product is a high-performance plastic shell circuit breaker, which is suitable for low-voltage terminal distribution circuit breakers in the fields of industry, civil buildings, energy, communications and infrastructure. It complies with the standards of GB/T14048.2 and IEC60947-2. This product has accurate protection characteristics, high breaking capacity, stable action performance, small size and beautiful appearance.
