· Standard: IEC60947-1; IEC60947- 2

· Rated Voltage: AC 400V

· Rated Current: 32A~800A

· Number of Poles: 3, 4

· Mechanical Life (With maintenance): 20000 times (for NDM3E-125, NDM3E-250);

10000 times (for NDM3E-400, NDM3E-630);

5000 times (for NDM3E-800).

· Rated Ultimate Breaking Capacity Icu AC 50Hz 400V: 50kA~100kA

· Rated Operating Short Circuit Breaking Capacity Ics AC 50Hz 400V: 35kA~65kA


· Communication function: The breaker can be connected with computer to realize remote control, remote-adjust, remote-meter and remote-information.

· Overload alarm non-tripping function: The breaker is with overload alarm non-tripping function. Once the breaker is set with this function, it will not trip when there is overload. Overload signal will be sent through output node to ensure continuity of power supply.

· Protective function against grounding fault: The breaker with protective function against grounding fault can protect the circuit against grounding fault.

· Rapid installing internal accessories: The whole series product can be equipped with modular accessories rapidly.

· 3-segment protection functions: The breaker can provide protection functions against overload, short-circuit with delayed trip and short-circuit withinstantaneous trip. It can be adjusted by customers.

· Self-power: Intellectual controller is powered by circuit breaker itself.

· Pre-alarm indication: LED "Alarm" on the panel flashes and then lights solid when the actual current reaches or exceeds pre-alarm tripping threshold Ip.

· Overload indication: LED "Over" lights solid when the load current exceeds long-time overload tripping threshold.

· Instantaneous tripping function at large current: Breaker is tripped directly by electromagnetic trip unit when there is large current during operation.

· Various connection types and accessories available.

Q:What is the common circuit switch called switch
Over-current release with electromagnetic, electronic and intelligent release, and several several
Q:Home circuit breakers and how much air is open
The air switch has an average operating life of 20000 times at rated load. In the understanding of the leakage switch,
Q:How to look at the circuit breaker capacity is how much?
As the high-voltage current in the process of breaking, the arc, even if the circuit breaker contacts are separated,
Q:Load switch, vacuum switch and circuit breaker
Load switch: can safely cut off the load current, can not cut off the short circuit current
Q:Circuit system diagram how the circuit breaker said
Therefore, the disconnector can only be in the circuit has been broken when the circuit breaker to operate, is strictly prohibited with the load operation
Q:How is the total switch breaker in the distribution box correctly
Cut off the power to complete the task of leakage or electric shock protection.
Q:Circuit problem! Hurry Miniature Circuit Breaker!
such as the access line loose, due to contact resistance becomes larger, will cause heat to make the circuit breaker malfunction.
Q:Is the isolator switchable with a circuit breaker?
the disconnector can not be used to turn on or off the current, it is only broken in the case of breaking the circuit breaker, to provide a "clear break point."
Q:he circuit breaker in the circuit mainly plays a protective element what protects the two functions of the element
he circuit breaker is composed of a thermal element and a current coil, and when the circuit current exceeds the rated value
Q:What is the difference between a circuit breaker and other switches?
replace the contacts and components more convenient, and more used in the power side of the main switch
