① 800 A high‑current carrying capacity. It can be deployed as the main incoming cabinet to supply backbone power for the entire low‑voltage distribution system, ideal for high‑load sites such as large‑scale industrial and commercial facilities.

② High short‑circuit withstand performance. It withstands high‑current surges caused by system short‑circuits and delivers stable, dependable operation to safeguard the power‑distribution installation.

③ Modular draw‑out structure. Drawer units support flexible configuration and fast replacement for simplified maintenance. Distribution circuits can be adjusted conveniently according to actual power‑consumption demands.

④ Intelligent protection capability. The main circuit breaker provides fully selective protection, accurately identifying fault types to achieve selective tripping and prevent fault propagation.

⑤ Optional intelligent monitoring system. Real‑time tracking of distribution‑system operating parameters with automatic alarms for abnormal conditions enables smart operation and maintenance.

Backbone power distribution and energy allocation for high‑load scenarios, including low‑voltage power distribution systems of large‑scale industrial workshops, main power distribution for commercial complexes, low‑voltage power distribution systems in data centres, main power distribution for hospitals, power distribution for large‑scale office buildings, underground mine power distribution, power distribution for ports and wharves, and power distribution for large‑scale hotels.

Q1: What power load can an 800 A distribution cabinet handle?
A: Under AC 380 V three‑phase operating conditions, the 800 A rated current corresponds to approximately 400 kW, which satisfies main‑distribution demands of large industrial workshops and commercial complexes.

Q2: What type of distribution cabinet is the LDPA series?
A: The LDPA series is a low‑voltage draw‑out‑type switchgear. Its modular drawer‑based structure brings easy maintenance, flexible circuit configuration and enhanced safety, making it a widely adopted cabinet type for industrial and building power‑distribution systems.

Q3: Does it support selective protection?
A: The standard‑fit intelligent air‑circuit breaker offers full selective protection. It enables selective coordination between upstream and downstream breakers. Upon a fault, only the faulty circuit trips without disrupting power supply to other healthy circuits.
