商品詳細
GCS and MNS withdrawable Low Voltage Distribution Cabinet are standard drawer-type metal-enclosed distribution cabinets designed for 0.4KV three-phase low-voltage power distribution systems. Widely applicable to industrial production, commercial construction and public power grid systems, these cabinets focus on flexible power distribution, stable system operation and convenient daily maintenance, solving the pain points of traditional distribution equipment such as poor flexibility, troublesome overhaul and insufficient expandability. Balancing economy and performance, they fill the gap between entry-level fixed switchgears and high-end customized power distribution equipment, occupying an important position in modern industrial power distribution fields.
コア製品の優位性
1.Modular Drawer Structure, Ultra-Convenient Maintenance
The whole equipment adopts an independent modular drawer design, with each functional drawer operating as a separate unit. In the event of circuit failure or component aging, the faulty drawer can be directly pulled out and replaced independently, without shutting down the entire cabinet or interrupting the overall power supply. This design greatly shortens equipment maintenance time, reduces power outage losses, and effectively guarantees the continuous and stable operation of the power distribution system.
2.Standardized Manufacturing, Stable Quality & Lower Cost
Adopting an integral fully assembled structure and standardized production process, all internal parts and components feature high universality and interchangeability. The unified production standard effectively stabilizes product quality and reduces the failure rate of equipment operation. Meanwhile, the high versatility of accessories greatly lowers subsequent daily maintenance, component replacement and equipment operation costs, bringing long-term economic benefits for users.

さらに表示よくある質問
What's the difference between LV and ELV?
LV (Low Voltage) typically covers AC voltages above 50 V up to 1000 V, or DC up to 1500 V. ELV (Extra‑Low Voltage) is a touch‑safe subset of LV, with AC peak values not exceeding 42.4 V or DC values not exceeding 60 V (e.g., USB, doorbells). The main difference is safety – ELV generally does not require additional shock protection, while LV does.
What is low voltage distribution?
It is the process of delivering electrical power from a distribution transformer to end‑users or equipment at voltages below 1000 V (AC). It splits the main supply into multiple branch circuits, providing protection and control for residential, commercial, and industrial loads.
What is a low voltage distribution panel?
It is an enclosure that receives power from a transformer or generator and distributes it to various branch circuits. It contains busbars, circuit breakers, fuses, relays, and control devices, acting as the central hub for safe power allocation within a building or facility.
What are the examples of electrical cabinets?
Common examples include main LV switchgear cabinets (for primary distribution), motor control centers (MCCs) for multiple motors, wall‑mounted distribution boxes in residential/commercial sites, and power factor correction cabinets. They are classified by voltage, current type, or function (supply, protection, control).
What is the IEC 60947 standard for low voltage switchgear and controlgear?
IEC 60947 is a series of international standards covering LV switchgear and controlgear such as switches, disconnectors, fuse‑combination units, contactors, relays, and control circuit devices. It specifies performance, testing, and safety requirements for equipment rated up to 1000 V AC or 1500 V DC.
What is the voltage range of LV switchgear?
LV switchgear generally covers AC systems up to 1000 V and DC systems up to 1500 V per IEC definitions. Some regional standards (e.g., IEEE) may extend DC limits to 3200 V. In practice, the common range is 50–1000 V AC for most distribution applications.
