Operation & Status Indicators
This section details the system's visual feedback and user control interface.
Indicator Definitions
- Run Indicator: Constantly on after power-up; flashes once every second during communication.
- Fault Indicator: Illuminates if the internal heatsink temperature is too high or if the external temperature sensor wire is open/shorted.
- Alarm Indicator: Lights up during overvoltage, undervoltage, overload, short circuit, internal/external overheating, or excessive leakage current.
- Short Circuit Indicator: Activates when a short circuit is detected in the load equipment.
- Silence Indicator: Illuminates when the alarm or fault sounder is silenced.
- Closed Switch Indicator: Lights up when the circuit is closed and turns off when open.
Button Definitions
- Self-Test: Restarts the device and checks the buzzer, indicators, and LCD screen.
- Set: Enters the settings menu to configure thresholds, protection parameters, and delay times.
- Reset: Regardless of whether the device is in a normal, alarm, or fault state, this rechecks all channel parameters and determines the status.
- Query: Allows you to check the device number, alarm records, and power consumption data.
- Silence: Mutes the alarm sound. The silence indicator remains on, but the alarm status is not cleared until the channel parameters return to normal.
- Return: Exits to the previous menu level.
- Direction: Used to move the cursor or change numbers.
Frequently Asked Questions
What rated current options are available for this smart circuit breaker?
The device is available in six rated current options: 20A, 32A, 40A, 50A, 63A, and 80A, making it suitable for a wide range of residential and commercial electrical load requirements.
What communication protocols does the smart circuit breaker support?
It supports RS485 wired communication as standard, with optional wireless connectivity including LORA, NB-IoT, and 4G, enabling flexible integration into smart building and IoT monitoring systems.
What types of protection does this device provide?
The breaker offers comprehensive protection including short circuit (<150µs response), overload, overvoltage (221–300V), undervoltage (100–219V), wire temperature monitoring (0–85℃), and leakage current monitoring (30–1000mA). Each protection type supports user-configurable delay times from 0 to 60 seconds.
How is the smart circuit breaker installed?
The device uses bottom screw mounting and has product dimensions of 300(L) × 210(W) × 140(H) mm. It is designed for straightforward installation in standard electrical enclosures or distribution panels.
What does the Silence button do, and does it clear the alarm?
The Silence button mutes the audible alarm sound and activates the Silence Indicator. However, it does not clear the alarm status — the alarm remains active until the monitored channel parameters return to their normal range.
What is the operating temperature range for this device?
The smart circuit breaker is rated to operate reliably across a wide temperature range of -20℃ to +85℃, making it suitable for both indoor and outdoor electrical installations in various climatic conditions.
