Low Voltage Drawer Type Switchgear Cabinet

Built for AC 50–60Hz systems with rated working voltage up to 660V, our Low Voltage Drawer Type Switchgear Cabinet at Usune supports power distribution, motor control, and power factor compensation. Industrial plants, power facilities, petrochemical projects, transportation infrastructure, commercial buildings, and other low-voltage systems can all use it.

Why Drawer Design Matters

In a conventional fixed cabinet, circuits depend heavily on the overall arrangement—awkward when a facility has many independent loads, since circuit management and later modification become harder. A drawer-type layout splits electrical functions into individual units: each drawer maps to a specific feeder, motor, or load, so the cabinet follows the actual distribution structure. Factories and large facilities can thus plan switchgear around electrical loads rather than cabinet dimensions.

Circuit-by-Circuit Management

Separate functional units let different circuits be assigned individually. A production facility, for example, may have independent circuits for conveyor motors, pumps, fans, auxiliary machinery, lighting, and general distribution, each arranged to its own electrical requirements. Operators can then trace the link between each circuit and its equipment—valuable in large electrical rooms with many outgoing feeders.

Different Loads, Different Drawers

Loads differ in power demand: a small auxiliary motor and a high-power production motor may need different switching and protection. Our Low Voltage Drawer Type Switchgear Cabinet therefore offers large and small drawers, with configuration set by motor ratings, feeder capacity, and circuit count—giving engineers more freedom in cabinet layout.

Motor Circuit Organization

Motor control can dominate the low-voltage system in industrial facilities. Our MCC configuration comprises large and small drawers, each circuit's main switching device being a high-breaking-capacity molded case circuit breaker or rotary load switch with fuse. Pumps, compressors, fans, conveyors, production machinery, and other motor-driven equipment can all be served, and separating motor circuits into dedicated units simplifies the relationship between each motor and its feeder.

Power Distribution Arrangement

Where incoming power must be divided among multiple downstream circuits, our PC cabinet applies. Depending on the approved design, it accommodates Emax, MT, 3WN, AH, and ME series circuit breakers; selection considers rated current, short-circuit capacity, feeder characteristics, protection coordination, and connected equipment requirements.

Reactive Power Management

Motor-heavy systems can generate significant reactive power demand, so power factor compensation may form part of the design. Our compensation cabinet supports manual, automatic, or remote compensation, configured to the customer's load characteristics and electrical management requirements rather than a one-size-fits-all arrangement—making our Low Voltage Drawer Type Switchgear Cabinet adaptable across projects.

Where It Fits

The equipment can be adapted to electrical systems with different load structures.

Manufacturing Facilities

Factories with multiple production lines can use separate drawer units for motors, auxiliary equipment, and general power circuits.

Petrochemical Plants

Pumps, compressors, fans, and other process equipment can be arranged through dedicated motor control circuits.

Steel & Metallurgy

Large production facilities can use centralized low-voltage distribution for multiple high-power equipment and motor feeders.

Transportation Infrastructure

Railway facilities, terminals, and supporting infrastructure can use the cabinet for equipment power distribution and auxiliary electrical systems.

High-Rise Buildings

Commercial and residential buildings can organize multiple low-voltage feeders within a centralized distribution system.

Energy Facilities

Power plants and energy projects can configure distribution, motor control, and compensation functions according to their auxiliary electrical loads.

Quality & Compliance

At Usune, ISO 9001, ISO 14001, and ISO 45001 underpin both production and management.

Equipment is built to applicable IEC and GB requirements—GB 7251.1 and JB/T 9961 among them—together with relevant international requirements for low-voltage switchgear and controlgear assemblies.

Configuration Before Purchase

For procurement teams, the most important step is confirming the electrical configuration before manufacturing.

A Low Voltage Drawer Type Switchgear Cabinet should be selected according to the actual load list rather than only the cabinet's rated voltage.

Usune recommends confirming:

Providing these details during the quotation stage allows Usune to prepare a configuration that better matches the customer's actual electrical system.

Factory Production

The cabinet is assembled at the factory using standardized cabinet structures and functional components.

The production process covers component inspection, structural assembly, drawer installation, electrical wiring, functional-unit inspection, and routine testing.

This factory-based assembly process allows the final cabinet configuration to be checked against the approved technical requirements before shipment.

FAQ

What voltage can the cabinet handle?

The equipment is designed for AC systems with rated working voltage of 660V and below.

Why use a drawer-type configuration?

The drawer arrangement allows individual electrical circuits to be organized as separate functional units, which can make large distribution systems easier to manage and configure.

Can large and small drawers be combined?

Yes. The MCC configuration can use both large and small drawers according to motor capacity and circuit requirements.

What equipment can be installed in the PC cabinet?

The PC configuration can use Emax, MT, 3WN, AH, and ME series circuit breakers according to the approved project design.

Is it suitable for motor control?

Yes. The MCC section is specifically designed for multiple motor circuits and can be configured with different drawer sizes.

Does it support power factor compensation?

Yes. Manual, automatic, and remote compensation functions can be configured according to project requirements.

What certifications does Usune have?

Usune operates under ISO 9001, ISO 14001, and ISO 45001 management systems. Products are manufactured according to applicable IEC and GB standards, with CE certification available for applicable configurations.

Can Usune customize the cabinet?

Yes. Drawer quantity, circuit arrangement, breaker selection, MCC configuration, and compensation functions can be determined according to the customer's electrical requirements.

What information should be provided for a quotation?

The most useful information includes system voltage, incoming current, number of feeders, motor quantity and ratings, short-circuit level, compensation requirements, installation environment, and the electrical single-line diagram.
