Structural Features

● This device is designed for floor installation and can be directly installed under the transformer. The cabinet is constructed from high-quality steel plates, welded or assembled. The operating handle of the knife switch is installed on the right column of the cabinet, serving as a power cut-off and switching mechanism.

● A voltmeter is installed on the front of the power distribution box to indicate the voltage of the busbar. The front of the power distribution box is equipped with a door, which, when opened, exposes all equipment inside for easy maintenance.

● The power distribution box utilizes newly designed components domestically developed, featuring compact structure, convenient maintenance, and flexible circuit arrangement.

● Circuit breakers are incorporated into the power distribution box for short-circuit protection, and operation buttons can be installed in front of the door.

● Operation Mode: Manual

● Installation Method: Vertical Installation

● Wiring Method: Fixed Wiring

Operating Environment Requirements

● The altitude should not exceed 4000 meters.

● The ambient temperature or surrounding air temperature should not exceed +40°C, with an average temperature not exceeding +35°C within a 24-hour cycle. The surrounding air temperature should not drop below -10°C.

● The air should not contain an excessive amount of dust, acid, salt, corrosive, or explosive gases.

● The relative humidity should not exceed 50% at the highest temperature of +40°C. However, at lower temperatures, higher relative humidity is permitted, such as 90% below +20°C, but occasional condensation due to temperature changes should be considered.

● Special requirements from the user can be addressed through consultation with our company.
