Modern distribution boxes need to have a variety of functions to ensure safe, efficient and controllable power distribution. Here are some common modern distribution box features:

Circuit protection: Distribution boxes need to have circuit protection functions, such as fuses or circuit breakers, to prevent fire or equipment damage caused by current overload, short circuit or malfunction.

Ground fault protection: Distribution boxes should have ground leakage protection devices to detect current leakage to the ground to reduce the risk of electric shock.

Remote monitoring: Some modern distribution boxes have remote monitoring functions, which can remotely monitor power usage through the network to improve energy efficiency and fault detection.

Automation: Automatic power cut-off and restoration functions can improve power system reliability and reduce outage time.

Power quality monitoring: Distribution boxes may contain power quality monitoring equipment to detect voltage fluctuations, harmonics and other issues to ensure that power quality meets standards.

Overload protection: The distribution box should have an overload protection mechanism to prevent the circuit from overloading and triggering an automatic power outage.

Fire protection functions: Distribution boxes should have fire protection functions, such as flame retardant materials and fire isolation, to reduce fire risks.

Intelligent control: Some modern distribution boxes have intelligent control functions that can adjust circuits in real time according to power demand to improve energy efficiency.

Current Measurement and Metering: Distribution boxes often include current measurement and metering devices to monitor electrical energy usage.

Security Lockout and Identification: Distribution boxes should have security lockout and identification features to ensure access and operation by only authorized personnel.

These features can vary based on specific uses and requirements, but modern electrical distribution boxes often incorporate a variety of technologies and features to provide safer, more reliable and efficient power distribution.
