Low-voltage switchboards supplied by we Seonjinhitech are equipped with proven pull-out air circuit breakers (ACB) and self-protection circuit breakers (MCCB). They are designed and manufactured in accordance with IEC and KEM standards, ensuring the best quality by applying devices with proven safety and durability through sufficient bus capacity, installing circuit breakers with excellent breaking performance and protective relays with appropriate protection elements. In addition, the compact design increases the utilization rate of electrical room area, and the two-stage and three-stage design reduces facility costs.

√  Improved stability and economy through appropriate circuit breaker placement

√  Customized design and manufacturing to meet various domestic and international standards and user specifications

√  Easy maintenance and modification of products

  ◐  Manufacturing Spec. of LVDP  

  ◐  Configuration of LVDP  

Low voltage switchboards (LV switchboards) are generally equipment that reduce voltages of 6.6kV or 22.9kV to distribute power below 600V, 

and are mainly composed of the following basic circuits.

1)  Main Circuit

     Distributes the main power coming from the power source to each load, and includes circuit breakers (MCCBs), magnetic contactors (MCs), 

     and relays.

2)  Branch Circuit

     A circuit that supplies power to individual loads (lighting, outlets, machines, etc.) and is protected by a miniature circuit breaker (MCB).

3)  Control Circuit

     Controls functions such as motor start, stop, and timer operation, and uses switches, relays, timers, and push buttons.

4)  Metering Circuit

      A circuit for measuring current, voltage, and power, and includes ammeters, voltmeters, wattmeters, CTs, PTs, etc.

5)  Earthing Circuit

     This is a grounding circuit to prevent leakage and electric shock accidents.

Local distribution Panel is a device that distributes power and plays an important role in the lower level of electrical facilities. It divides the electricity coming from the main power source into several circuits and supplies them to different loads. It is a useful device for safely distributing and managing power, as it generally includes circuit breakers, fuses, and measuring instruments. The distribution board is mainly used in commercial buildings or industrial sites, and it greatly helps to increase efficiency and stability in the operation of the electrical system.

MCC control panel (Motor Control Center) is a centralized motor control system for efficiently controlling and protecting multiple motors. Its main components include magnetic contactors (MC), thermal relays (OLR), circuit breakers (MCCB), and measuring instruments. It can independently start and stop each motor, and also performs fault detection and protection functions. MCC is widely used in multi-motor control systems such as industrial plants and large-scale facilities.
