Overview

Industrial NB communication electrical protectors can overcome the drawbacks of traditional circuit breakers, air switches, and monitoring equipment, such as high short-circuit current, long interruption time of short-circuit current, large arc sparks generated during short-circuit, and short service life. When a short-circuit fault occurs, it can quickly limit the short-circuit current in microseconds to achieve arc extinguishing protection, thereby significantly reducing electrical fire accidents and ensuring the safety of personnel and property in the use area.

Product Details

Industrial NB communication electrical protectorFeatures

1) Short circuit protection function. The protector monitors the current of the power line in real time. When a short circuit fault occurs in the line, it can achieve fast current limiting protection within 150 microseconds and emit sound and light alarm signals.

2) Overload protection function. When the current of the protected circuit is overloaded and the overload duration exceeds the action time (3-60 seconds can be set), the protector starts the current limiting protection and emits an audible and visual alarm signal.

3) Internal over temperature protection function. When the working temperature of the internal components of the protector is too high, the protector implements over temperature current limiting protection and emits an audible and visual alarm signal.

4) Overvoltage and undervoltage protection function. When the protector detects undervoltage or overvoltage of the line voltage, it emits an audible and visual alarm signal, and can pre-set whether to activate current limiting protection. 5) Temperature monitoring function for distribution cables. When the temperature of the monitored cable exceeds the alarm set value, the protector emits an audible and visual alarm signal, and can pre-set whether to activate current limiting protection.

6) Leakage current monitoring function. When the monitored circuit leakage exceeds the alarm set value, the protector emits an audible and visual alarm signal, and can pre-set whether to activate current limiting protection.

7) The protector has 1 RS485 interface and 1 2G or NB IoT wireless communication. Data can be sent to the backend monitoring system for remote monitoring. The monitoring backend can be the Acrel-6000/B electrical fire monitoring host, the Acrel-6000 secure electricity management cloud platform, or a third-party monitoring software or platform

Characteristics of NB Communication Electrical Protector

Fast current limiting protection

When a short circuit fault occurs, it can achieve fast current limiting protection within 150 microseconds, effectively suppressing electrical fire accidents caused by excessive short circuit current.
Adopting solid-state switch technology, the breaking time is microsecond level, with fast speed and no arc generation, far exceeding traditional mechanical switches.

overload protection

Real time monitoring of power line current, when the line continues to overload and exceeds the set time, activate current limiting protection to avoid overheating of the line and causing fires.

overtemperature protection

Monitor the temperature of internal components or circuits of the protector, and implement current limiting protection when the temperature rises abnormally to prevent overheating and fire hazards.

Over

When detecting abnormal voltage in the circuit, an audible and visual alarm signal is issued, and it is possible to pre-set whether to activate current limiting protection to ensure that the equipment operates within a stable voltage range.

Other functions

Temperature monitoring of distribution cables: Monitor the temperature of protected cables and issue an alarm signal when it exceeds the set alarm value.
Leakage current monitoring: Monitor the leakage situation of the circuit and issue an alarm signal when it exceeds the set value.
Fault arc detection (optional): Detect fault arcs and provide early warning of electrical fire hazards.

Industrial NB communication electrical protector function

short circuit protectionShort circuit protection time is less than 150 microseconds, which can quickly cut off the faulty circuit and prevent electrical fires.
overload protectionThe action range is 100% -120% of the rated current, and the action delay is adjustable from 3-60 seconds to avoid equipment damage due to overload.
Residual current protectionMonitor the leakage current of the circuit, issue an audible and visual alarm when the leakage exceeds the set value, and pre-set whether to activate current limiting protection.
alarm functionSupport sound and light alarms to remind users to handle faults in a timely manner.
