The LY50 power distribution cabinet is designed with a rated current range of 250 A to 630 A and is widely used in industrial, commercial, and residential buildings for primary (first-level) power distribution. It typically supplies power to terminal distribution and control boxes, such as elevator power cabinets, fan control boxes, pump control boxes, and other downstream electrical equipment.

Key Features:
Protection Functions:
Equipped with short-circuit protection and overload protection to ensure the safe operation of electrical systems.

Fire Prevention:
The cabinet can be fitted with residual current fire monitoring devices and temperature sensors to detect leakage current and overheating, providing early warning and prevention of electrical fires.

 Power Monitoring:
Integrated with current transformers (CTs) and smart multifunction meters, it supports real-time monitoring of key electrical parameters, including:
Voltage
Current
Active power
Reactive power
Other essential power quality data

This cabinet is ideal for high-reliability, data-visible, and safety-critical power distribution scenarios.
