① 800 A high‑current carrying capacity. Deployed as the main incoming cabinet within low‑voltage systems to supply backbone power for the whole installation, well‑suited for high‑load sites including large‑scale industrial and commercial facilities.

② High short‑circuit withstand capability. It withstands high‑current impacts occurring during system short‑circuit events, delivering stable and reliable operation and safeguarding overall distribution‑system safety.

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

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

⑤ Optional intelligent monitoring system. Real‑time tracking of operational parameters with automatic anomaly alerts enables smart operation and maintenance of the power‑distribution infrastructure.

Backbone power distribution and electric 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 supply 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 support?
A: At AC 380 V three‑phase operating conditions, 800 A rated current corresponds to approximately 400 kW, satisfying main‑bus distribution demands for large industrial workshops and commercial complexes.

Q2: What cabinet type is the LDPA‑series distribution cabinet?
A: The LDPA series belongs to low‑voltage draw‑out switchgear. Featuring a modular drawer‑type structure, it offers easy maintenance, flexible circuit configuration and enhanced safety, and represents a widely‑adopted cabinet solution for industrial and building power‑distribution systems.

Q3: Does it support selective protection?
A: The unit comes standard with an intelligent air‑circuit breaker equipped with full selective‑protection capability. It enables selective coordination between upstream and downstream breakers. During a fault, only the defective circuit trips while other circuits remain energized.
