Description

The DC smart circuit breaker is a product developed to meet the needs of DC power distribution systems and communication base stations for differentiated power supply, energy saving and consumption reduction.

It is suitable for power-consuming equipment with an operating voltage of DC48V and a current of 100A or less. It can be configured as needed according to on-site conditions and supports cascade expansion

Function

1. High-precision measurement and metering

The current and voltage measurement accuracy is up to 0.5 level; the active power and reactive power are up to 1 level or above

2. Comprehensive monitoring

Measurement information: current, voltage, leakage, temperature, frequency;

3. Double tripping

Built-in double tripping drive mechanism (patented technology) ensures fast and reliable circuit disconnection.

4. Extended linkage

With the DI\DO function, it can realize regional interlocking with upper and lower level circuit breakers to achieve selective protection.

5. Adjustable electrical parameters

Current and voltage protection values ​​are adjustable; leakage protection value is adjustable; action type is adjustable.

6. Adjustable warning threshold

The voltage, current, cable temperature, and residual current protection alarm values ​​can be set, and the ignition alarm can be supported. It supports the setting of overload, overcurrent, overvoltage, etc.

7. Leakage self-test

The device can be remotely controlled for self-test, and the device can be set to automatically self-test;

8. Records are not lost

Built-in clock circuit and button battery, data and fault records are not lost after two years of power outage;

9. Energy consumption analysis

Supports power consumption analysis, and uploads power, power factor, electric energy and other energy consumption information to the cloud platform for analysis and display in real time;

10. Remote control

Can remotely control, set the timed opening and closing of the circuit breaker, and set the timed closing and opening;
