描述

The DZ47-63 Miniature DC circuit breakers are key protective devices in DC circuits, primarily used for controlling circuit on/off and providing fault protection. Their core functions are as follows:
一、Circuit On/Off Control
Normal On/Off Operation
Manually or electrically control the switching on and off of DC circuits. For example:
Control the connection between solar panels and energy storage devices in photovoltaic systems;
Start or stop backup power supplies (UPS) or battery packs in communication base stations;
Serve as power switches for electric vehicle charging piles and DC lighting systems.
They support infrequent operation (to avoid contact wear from frequent switching), making them suitable for scenarios requiring flexible power control.
Power Isolation
When circuit maintenance or repair is needed, tripping the circuit breaker completely isolates the power supply, creating a clear electrical disconnection point to prevent electric shock and ensure personnel safety
