Up to 36 Drawers in One Cabinet — Highest Density in Class
The compact Ω-profile frame design allows up to 36 outgoing circuits per cabinet — the maximum reasonable installation density in the relative space. Same-unit drawers can be interchanged between different positions without disconnecting power or control cable wiring, dramatically simplifying spare-parts planning and reducing maintenance downtime.
Modular Drawer Layout — 6 Rows × 6 Columns
36 modular drawer positions per cabinet. Each drawer is independently serviceable, and any drawer can be exchanged for another of the same functional unit type without removing adjacent drawers or disconnecting main power wiring.
Form 3b/4b Internal Separation
Three-Layer Metal Partition Architecture
LAYER 01 Functional Unit Compartments Separated by steel plates between adjacent functional units (Form 3b/4b)
LAYER 02 Horizontal Busbar Compartment Metal partition between busbar and functional units · cable compartment separated
LAYER 03 External Conductor Terminals Isolated from other unit terminals and busbars (Form 4b only)
The Form 3b/4b separation prevents fault propagation between switch components caused by failures in other compartments or busbars, ensuring operator safety during maintenance and inspection. Form 4b adds separation of external conductor terminals from other functional units — the highest level of internal separation defined in IEC 61439-2.
ARC630 Arc Protection System
Active Arc Quenching — The Fastest Response in Class

Active quenching
The ARC630 system delivers the highest level of safety protection in the LSN series. Unlike passive arc containment solutions that rely on enclosure pressure resistance, ARC630 actively detects and quenches the arc within milliseconds of ignition — well before the pressure wave can reach the enclosure walls. This substantially reduces the risk of burn injuries to operators and minimizes equipment damage in the unlikely event of an internal arc fault.

Frequently Asked Questions
What is Cooper Edison LSN low voltage switchgear?
Cooper Edison LSN is a modular low voltage switchgear developed by Edison Electric R&D Center (Shanghai) of Cooper Power Systems, designed for three-phase AC 50-60Hz systems at 690V and below. It serves as a low voltage motor control and power distribution center, widely used in power plants, substations, and industrial facilities. The LSN combines Cooper's century of distribution system design experience with modular drawer architecture, Form 3b/4b internal separation, and ARC630 arc protection.
What is the rated current and withstand capacity?
The Cooper Edison LSN main busbar rated current reaches up to 6300A, with rated short-time withstand current up to 100kA/1s (RMS) and peak withstand up to 220kA. This makes the LSN suitable for high-power industrial distribution systems and heavy motor control centers where short-circuit levels are severe.
What is Form 3b/4b internal separation?
Form 3b/4b refers to the internal separation levels defined in IEC 61439-2. Form 3b separates functional units from each other and from the busbar using metal partitions. Form 4b adds separation of external conductor terminals from each functional unit. The Cooper Edison LSN adopts Form 3b/4b with metal partitions between busbar compartment and functional units, effectively preventing fault propagation between compartments and ensuring operator safety during maintenance.
How many circuits can fit in one LSN cabinet?
The compact Ω-profile frame design allows up to 36 outgoing circuits to be installed in a single Cooper Edison LSN cabinet — the highest usage density in its class. Same-unit drawers can be interchanged between different positions without disconnecting power or control cable wiring, which greatly simplifies spare-parts planning and maintenance.
What is the delivery time and MOQ?
Standard configurations ship within 30-60 days from order confirmation, depending on the number of functional units and whether VFD or motor starter modules are included. MOQ is 1 unit. Custom busbar ratings, protection schemes, or communication integration may require 60-90 days. We accept sample orders for validation testing.
Can LSN integrate with a prefabricated substation?
Yes. The Cooper Edison LSN is designed to fit into RAYDAFON YBM prefabricated substations. For turnkey distribution projects, both the LV switchgear and the prefabricated substation can be supplied from one source. See prefabricated substations →
